Elevance Clean 1200 and Plexiglass


If this video does not show on your phone please go to the link for my channel at the bottom of this post.

Clean 1200 is an excellent solvent.  True it is rather stinky but it is very powerful.  I put it through a very hard test here.  The paint that I used was a very strong paint.  Very thick.  Then I let it cure for a full month.  It was extremely difficult to get off even with a single edge razor.  But after a full hour of dwell time with the Clean 1200 I could scratch it off with my finger nail slowly.  When looking for a great solvent you will want one that has a very slow evaporation rate.  I did this test in 85 degree weather.  This allows you to let it set for a full hour.  Which will only make your job that much easier.  Otherwise even the most powerful solvent won't work at all.  Another thing is you will want a solvent that is miscible in water.  So a soapy water solution will quickly remove all of the residue.  Again the Clean 1200 is rather stinky so I would not use it inside.  But if you are working on a non-routine job and have your waiver signed, just use caution and make sure you clean up very well.

Now what we need to know is that even though the Clean 1200 is safe for glass and likely for tin oxide low e coatings as well;...it is absolutely NOT safe for plastic glazing.  This would be all three.  Not acrylic as is demonstrated here, nor polycarbonate, and or polyester/mylar.  I think how it crazes acrylic is the most demonstrative.  But the potential damage which can be done to the other two can also be quite bad.  Also non repairable!

Just to explain a little about what I have demonstrated.  When plexi is exposed to even the residue of most solvents and any type of physical stress, then it will craze.  That is crack up.  Such cracks can be long or zillions of very fine cracks depending on conditions.  The physical stress can be as I have shown here.  Or it can be vibrations from sound or just the constant slamming of a plexiglass door.  It can even be tight screws holding a plexi storm window on.  The stress might have been there for literally years.  But when you come along and use your wonder solvent to get some paint off, you could easily end up with cracks all around the edge where the screws were used.

I won't get into the chemistry and the physics of micro-fissures.  But you get the point!  In time I will post more videos on this topic.  So stay tuned to the channel and blog.  My goal is to educate and entertain.

Kleer Vu Demonstration

  





Contact Information;
Karen Wright
Kleer Vu Sales
3005 N 4th E
Idaho Falls, Idaho 83401
208-524-4949

This product is based on a very special surfactant blend that attracts water when applied to glass and even plastic surfaces.  Which by the way are by nature quite hydrophobic, not hydrophylic!  It works very well on mirrors as you can see here.  Also sunglasses, regular glasses, swimming goggles, ski goggles, and many more situations.  What I am holding here is a two ounce bottle which fits very easily in your pocket or purse.  So you can carry it around wherever you go.

How does it become a "private label" product?  All you have to do is create your label on a computer using a graphics program.  Then send that by email attachment to Karen.  Tell her you found Kleer Vu on my YouTube Channel and Blog.  Then she has a print shop that they have negotiated the best price with who will print up a bunch of labels based on your artwork.  So be creative!  She will then fill the bottles with their anti-fog formula and send back to you however many bottles you want at the moment.  You will get a wholesale rate on the bottles and be able to sell them directly to your window customers for a good profit.  Once your customers get hooked they might even want to sell them to friends.  The most important benefit to you however is that the bottles become a business card.  Cards are just filed away and no one sees them again.  But these little bottles (or larger) of anti-fog will be carried around in purses or pockets.  People will be looking at them all the time.  Make sure all of your contact info is on the label.  Because one little bottle of anti-fog could win you a thousand dollar job.

I am working on a few other private label products right now that will work just as well as this one and maybe even better.  This is the way people.  Forget your business cards and flyers.  Private label products are the very best way to advertise your business!

NG1010 & Protection Tech

The window cleaning company that understands protection technology will win the storefront every time!  Think about it.  As a company that specializes in storefront accounts you make your money by cleaning the same windows hundreds and possibly thousands of times.  So what if we did a demonstration of how a very special chemical sealant can actually prevent scratches on doors and other windows.  Show how we can remove light scratches and light stains.  Show how glass can be easily damaged by the wrong hands but actually preserved by the more experienced worker.  Who do you think will get the job?

Protection technology is now a reality.  This is NOT routine window cleaning.  It is however a very advanced technology that will keep windows looking brand new for their entire life.  If someone is renting they might not care so much.  But how many large stores do own the building?  Usually these are restaurant chains.  One of the most profitable accounts.  Also one of the most difficult to maintain.

The Glass Smart YouTube Channel will be demonstrating these techniques.  You will be able to show these videos to your prospective customers and win the account.  If you were to walk in to a restaurant and show them which glass surface was scratch sensitive and how you could change this I am sure you would get attention.  Plus you would get the job.  Especially if the building was brand new.

Window cleaning companies that do not want to get involved with this technology will lose.  Just one account could cost you potentially hundreds of thousands of dollars.  Is it really worth it.  You just can't remain in the past thinking all you need is a mop, bucket, and squeegee.  Those days are long gone.  And the cleaning companies that realize it and move ahead will win the accounts.

NG1010 is in my opinion the best sealant we have in the States right now.  It came from Australia and is currently being manufactured and sold in these States by NanovationsUSA located in Florida.  There are many articles and videos in this blog demonstrating it.  Further there will be many videos in the Glass Smart YouTube Channel in time demonstrating it too.  Contact NanovationsUSA today and ask for a sample.  If you go to the Glass Smart Facebook Group (use the link on the left side here) you will find other guys testing it.  Talk with them to see what they say.  Some like Marc Tanner have videos you can watch.

This product covers the most square feet at the least expense.  It also goes on very quickly and will not cause any cloudiness.  It creates a crystal clear appearance.  It is in fact a sol/gel chemistry which is not organic as many of the other hydrophobic sealants are.  So the results are much more long lasting and resistant to alkali attack from hard water spots or concrete.

Liabilities & Issues Regarding Non-Routine Window Cleaning

When do we take on liability?

Let me be perfectly plain.  As soon as you put down the squeegee and soft applicator/wetting wand;...you take on liability.  When you turn on a drill motor for polishing the glass; pickup even a piece of steel, bronze, or synthetic wool; take a razor blade to the window; get out any chemical be it a solvent, acid, or alkali; or even use a plastic powder by hand or mixed with a chemical;....you become liable.  The reason why is very simple.  The process you are now using is NOT outlined as a common safe practice by the glass manufacturing association.  They do NOT endorse it.  Their suggestion is to simply use a mop and a squeegee.

Avoid Liability Through Education!

We must first educate ourselves.  Get out the GANA Bulletins.  Read them over.  Share this information with your customers.  I will be writing about these Bulletins here in this blog.  But you will find them through the IWCA Glass Committee.  Which I am assisting but am no longer a member of.  The IWCA has actually shared in writing joint bulletins with the glass manufacturers association.  These carry weight!  Further, they actually do state in very plain language, if glass surfaces are allowed to become covered with concrete, stucco, paint, wood stain, silicone caulk, silane concrete sealant runoff, and so on;....they have in fact become damaged.  Whenever "routine window cleaning" (a mop and a squeegee) procedures are incapable of removing any type of deposit, then the window is essentially wasted.  Those are my words.  You need to know this and so do your customers!

To read the IWCA/GANA Bulletins and access lots more unformation of glass surfaces from the IWCA use this link;...

https://www.iwca.org/glass-surface-information/

Knowing When To Walk

Better yet run!  If you have not become responsible for doing any further damage, and especially are not completely comfortable with any procedure to remove the deposit without doing harm to the surface;....then absolutely take your leave.  However before you do, educate.  If enough of us do this contractors especially will get the idea very quick that they must use protective measures once the glass has arrived for storage.  Yes storage.  Even before installation.  It should be inspected, protected, and safely stored.  Protected through the installation/construction process, and then cleaned at the end of the job.  I am looking into protection technology now and have already posted some interesting videos on my YouTube channel.

Avoid Liability With Waivers For Non-Routine Work

Get one!  Whenever someone says, go ahead and do it anyway, and you think you can and make gobs of money in the process, don't be ill witted, be smart, get a waiver signed.  You must first educate the customer.  Let them know exactly what they are facing here.  Explain what GANA says, show them those important lines in the bulletins.  Explain what the problem is, concrete, silicone, etc.  Explain that your procedure could do worse damage to the surface.  Exactly.  It could do worse damage.  This is always possible.  It could also and does many times "void the manufacturers warranty".

Identify The Surface and Avoid Liability

This will set you apart from other window cleaners.  It is usually rather easy to identify what the problem is and where it came from.  Concrete, hard water deposits, silicone, stucco, etc.  But these days it is absolutely NOT an easy matter to identify the surface.  This is ESPECIALLY true for any employees you have.  If you are a franchise/business owner it could very well be true for you!  If so how could you ever expect that of your employees!?  And the wrong move could very easily affect the liability of your company and that of the entire franchise.  So once again education is key here.  How do we identify the surface?  Is it a pyrolytic first surface tin oxide, what of a first surface AR, or an acrylic, polycarbonate, or polyester?  Does it have a pyrolytic hydrophobic coating applied right off the glass line at the factory?  These are becoming more common for shower doors and enclosures.  Why is this so important?  Because there are non-routine procedures out there which are considered perfectly harmless;....BUT THEY ARE NOT!  Take for example the use of razor blades.  On most glass surfaces they are harmless.  But more and more now, glass surfaces are becoming very "scratch sensitive".  To razors and other non-routine methods.  So even if you have identified that you are working on plain glass you need to ask yourself is it rough, and does it "fizz and pop"?  If so back off.  Immediately!  Then there are other surfaces like AR coatings, tin oxide pyrolytics, plastics, etc.  You would NEVER under any circumstances want to use any type of metallic means (such as a razor or wool) on these surfaces.  Once you identify this type of surface and feel the need to use other tools, (other then those used in routine window cleaning), back off.  In fact let me put it this way.  Educate, identify, educate again, walk away, or proceed with extreme caution with a waiver.  You might choose to expand on any of this advice.  The bottom line is to minimize liability as much as is reasonably possible.  Never think you are losing a ton of money.  The fact is that there is a ton of money left to make out there just by dragging rubber!

The Process of Limiting Liability

The procedure should always be one of education.  Both the customer, ourselves, and our employees.  How can windows be ruined?  What are the manufacturers cleaning recommendations?  Have they been violated?  Is our customer demanding assistance?  Have we obtained a legal waiver and has it been signed by the necessary parties?  But most important is to know when to just walk away!

My YouTube channel will help to educate yourself and your employees in identifying various surfaces.  Along with various techniques that can be used with caution in non-routine work.  I would be delighted if you came aboard and supported my efforts by subscribing!  The YouTube link is;...

Testing For Plastic Surfaces With A Simple Razor Blade


If you cannot see this video on your device just go directly to


First of all you will need to determine that the surface is absolutely NOT a low e metallic surface such as an AR coating or a tin oxide low e coating from Pilkington or another manufacturer.  These coatings are very easy to scratch with a razor and the razor will not "stick in" like it does on acrylic, polycarbonate, or mylar film.  So the razor tip will actually slide on such a metallic surface leaving a rather noticeable scratch!  Not good.  There are some simple tests for metallic surfaces such as a special electronic tool.  Or an LED flashlight.  Metal surfaces feel different as I demonstrated in another video.  

Nonetheless the tip of a razor applied gently to a plastic surface will actually sink in just enough so it will not move easily as demonstrated here.  This is true for plexiglass (acrylic), lexan (polycarbonate), and mylar (polyester).  Single edged scrapers and larger handheld razors such as this Triumph work very well.

Plastic glazing is turning up everywhere these days.  You would never want to scratch it as it can be very costly to replace.  Further if it has paint on it this might be one of those situations where it would be best to just walk away.  Especially if you do not have a foolproof way of safely removing whatever is on it.  If the owner is will to sign a waiver absolving you of any and all responsibility then have it it.  But again only if you feel very comfortable.  The most safe course to follow is just to walk away.  This does not mean you are not a professional.  Just show them this little video and they will know that you are!

Private Label Products


If you cannot play this video on your device go directly to the Glass Smart Product Development YouTube Channel at;...


Private Label Products are way better than a business card.  One reason is you can sell them to your customers and prospective customers.  You certainly can't sell a business card.  So you can make money off them.  Your customers can also sell them to their customers spreading word about your window cleaning business even further.  This will also earn you a greater profit.

Private Label Products are designed with your business name and contact information printed right on the label.  You design this and have it printed.  Take for example the company Nu Kleer.  They make a number of different products.  Their figurehead product being an anti-fog.  Which is a product that everyone needs.  It can even be sold in quarts or gallons to motels for bathroom mirrors.  A simple spray on wipe off anti-fog glass cleaner.  Works very well on eyeglasses, sunglasses, and swimming goggles.  I personally would not use it on the inside of car glass however.  Once it starts to wear off it will attract even more fog than before it was applied.  Then if you are asked to remove it this can be very time consuming and problematic.  Been there done that, am not going back!

You might need an MSDS.  Which Kleer Vu does have.  All you need to do is change the heading at the top to your own company name and contact info and you are golden.  If you do want to purchase product liability insurance you can.  I found a very reasonable policy once for a small start up.  The rates are always based on the total dollar volume of your annual sales. So if you are not planning on selling that much you should not have to pay that much.  Although if you do go over the amount you anticipate then definitely tell the insurance company asap so they can adjust your premium.  This is a safeguard for you.

The High Shine Slip

If you cannot view this video on your phone or other device just go straight to the Glass Smart Product Development YouTube Channel at;...

https://www.youtube.com/channel/UCKzhmAWtlsHJiwRd6WrgGyA

That was an old woman at the laundromat that I had take the video for me by the way.  You can see her over to the right just a little.  I will use anyone that is or isn't agreeable.

On these demo videos I will be breaking glass in many different ways.  Just thought you would like that.  And I have also chosen this name for my videography, "Breaking Glass Productions".  You can rhyme that any way you like.

Anyhow.  I have been talking about this surfactant chemistry for a long time now.  So have decided to simply show you what kind of toys I have been playing with.  In as concise a way as possible.  Of course.  Then get a little technical on the blog.

The name High Shine was chosen to honor Lee Burbidge of the WCM.  He published many high caliber high tech articles in that mag.  High Shine is his company name.  It is interesting that the inorganic chemistry of this product does leave a special shine on the glass.  Which can be one of its downsides since it can streak on very hot glass in the direct sun.  Very hot dark glass too.  Hey I am not a manufacturer.  So I can degrade my own products!  Although this is usually not a problem.  But.  What we are trying to accomplish here is to attain a formula that will give the kind of solution which allows for easy cleaning of phobic surfaces.

The High Shine video begins by demonstrating with pure water exactly how phobic the test window is.  What I do not mention during the video is that I did apply a phobic product (which I will not identify) on the left side about a couple feet in.  This is just to demonstrate that even a surface that phobic can be sheeted and squeegeed with the High Shine.  You can see that the left side is somewhat more phobic than the rest of the glass but the entire surface is in fact quite phobic.  

Now I mentioned that this product is a Slip.  Actually it can be used by itself without any other product.  It can also be used with any other product.  I like to use it with Dawn.  And in this video I am only using a very little bit of Dawn.  That is why the sudz are almost totally just not there.  But we still have adequate glide or slip.

Now you can get sudz with Dawn up until you mix a 50/50 Slip/Dawn.  Then the sudz disappear.  That is because the High Shine is based on a silicone superwetter.  Silicone surfactants are typically sudz killers.  So that is what is happening here.  This is an anionic nonorganic superwetting surface active agent.  Dawn is based on two very common anionic organic surfs.  It is the strange combination of these two surfs that form what appear to be "islands" in the bucket.  The sun was out bright so I got some good pictures of this effect which is in the video.

Currently I am looking for some manufacturers or distributors to start carrying some of these products.  It might even be a window cleaning company that takes it on.  Who knows!  As long as I can get the smallest piece of cheese.  I do know however I can't do it and really don't want to.  My love is and always will be "the toy box".  Just got to have it.  I also love show and tell.  The new tech these days has given me that.  Didn't have it 25 years ago when I started writing for the AWC.  Never could have imagined it either.

I have many other things coming down the tube for you.  The YouTube that is.  Stay tuned to the channel.  And please subscribe.  I get more power that way.

I Had A Dream



If this video does not show on your phone just go directly to the Glass Smart Product Development Channel at;....

https://www.youtube.com/channel/UCKzhmAWtlsHJiwRd6WrgGyA

Change is at times the most effective means by which we succeed.  It has taken me 25 years to accomplish this however.  Even at the advice of one of our industries greatest icons I still didn't listen.  The idea and dream I had for developing a newsletter for the window cleaning industry worldwide almost worked too many times.  So I have finally decided to completely abandon it for all time.  As for my love of research and writing this will nonetheless continue.  My hope is that it will never end.  Further I have so much available in the way of what we call social media to help me attain my goals.  I have this blog, the WCR online Forum, My two FB Groups (one secret and one public), and now the Glass Smart Product Development YouTube Channel.  All of this is helping me to learn and especially to disseminate what I have learned to window cleaners worldwide.  It is also helping me to organize and assemble a human machine for product development.  There are so many very smart people out there who have developed alternate technologies that you all can directly benefit from.  But the conventional way of bringing their products to market would be very time consuming.  To do this much quicker we need to get more people involved in this business.  This is what I am inviting and encouraging as many of you who will to do.  My intention is to help you as much as I can.  In the development phase of your products and then also in the marketing of them.  Not just to the window cleaning industry either.  But as Marc Tanner would say the sky is the limit.  There is no limit.  You are only limited by your imagination.

I am especially interested in working with companies like NanovationsUSA, General Chemical, and many others who have already launched several products.  I will be developing many videos that will demonstrate what these products will do.  Some of which even the manufacturers and sales people have no clue about.  Further I will be sourcing some very special ingredients like the silicon based super wetters as additives for trad work to easily clean phobic surfaces.  Whether these be new phobic surfaces such as Nanovations treated glass, and just plain phobic windows and or mirrors as demonstrated in one of my more recent videos.  Imagine that, as soap developed just for phobic surfaces.  No more chatter with a crystal clear result.  

Now the most important line of products I am working on right now, are those which you can either develop or buy yourself for youe own window customers.  The very first one is available RIGHT NOW!  It is an anti-fog that customers can use on their mirrors, swim goggles, or any other glass surface that develops a fog.  The company will private label it for you then send you the bottles.  Their is already an SDS created for it.  All you need to do is change the name and address at the top to your own.  Then either pass it out or sell it for a profit to your customers.  Can you really think of a better "business card"?  It will have all your contact info right on the bottle.  Which will be passed around.  In fact your customers might want to buy more from you for their friends.  As I say this is available right now.  There are two more I am working on.  The first is an anti-bacterial/viral cleaner for cell phones.  The second is a window paint that will stay put until it is time to be removed.  You can soap and squeegee right over it.  But when it is time for it to be removed it will peal right off.  No mess no fuss.  Just peal it off and roll it up in your hands dry.  Both of these products can easily be sold to your customers.  The difference is once again you own them.  And all of your contact information will be on them for your window cleaning business.

If you are interested in the Anti-Fog just send me an email and I will get you all the information you need to order a sample direct from the company you will be buying from.  These will be the people who will private label for you, bottle it, and ship it back to you for distribution.

Demonstrating Dynamic and Static Phylic Surfaces


If this video does not show on your phone then just go straight to the GS YouTube Channel.

https://www.youtube.com/channel/UCKzhmAWtlsHJiwRd6WrgGyA

This video begins by showing how incredibly phobic a glass surface can be.  This is a brand new mirror.  Notice how pure water beads up and runs off.  Not very good for WFP work at all!  The video continues to expose a new blend of soaps both carbon and silicon based.  All three are anionic so they won't leave much of a film.  But have a well balanced effect on water so just the right surface tension is accomplished for Trad work on phobic glass.  I next wanted to see if Universal Photonics SR Pad was adequate to convert a very phobic surface to a phylic surface.  But not!  If I gave it enough time I am sure it would have worked.  But you can see I was able to accomplish this much better with a lose compound by hand alone.  No machine.  Pure water just sheets over this newly converted phylic surface.  It is so phylic that not even a single water drop forms.  Totally perfect for WFP work!  But hold on.  This is just a dynamic phylic surface!  I can hear you say oh no, now what?  Well my friends there are actually two different phylic surfaces.  Dynamic is the kind that will sheet water that actively strikes it.  Such as from a WFP brush, window wetting wand, a heavy rain, etc.  You get it.  But condensate from a mist or steam from a hot shower is quite another matter.  For this we need a glass surface that has been chemically enhanced.  This can be performed in a number of different ways.  Here I have chosen a water based anti-fog product which you can buy.  It does not bond to the glass and so will wear off in a relatively short time.  But would be great if you wanted to private label it and sell to your customers.  Anyhow I applied it to the bottom half of my mirror.  Remember I totally converted the entire mirror surface to a dynamic phylic surface.  Which sheeted dynamic water very well.  But still allows microscopic beads of pure water to form as a fog.  Yet by applying the anti-fog I was able to change the bottom half of the mirror to a static phylic surface.  The upper part remained a dynamic phylic.  So in the video you can see clearly through the bottom half.  This will sheet even condensate from a hot shower!  The top half of the dynamic phylic surface on the other hand developed a thick fog.  The trick comes at the very end of the video when I pass a wetting wand up and down the entire plate showing how the entire surface can be sheeted with pure water.  This demonstrates the power of hydrophylic chemical treatments for glass.  They can be quite effective.  Products that do this are easy to get.  I do believe the one I demonstrated here is one of the best out there.  And you can buy it in large quantities if you want to put it in smaller bottles and repackage for advertising your business.  But it will still wear off in time because it is not a bonded reactive anti-fog product.  We need a polymer that forms a covalent bond with glass.  One that will convert dynamic phylic to static phylic and last.  I will keep you posted on this.  Cuz I am working on precisely this right now.  This is yet one more video in my series demonstrating the conversion technology of phobic to phylic.

The Destructive Power of Pure Water

Water alone has the power to do serious damage to glass in as little as thirty seconds!  I am talking about normal water with a normal pH, and no chemicals or special soaps added!  I have seen it happen.  A pressure wash company had just come through with a pure water spray and blasted a stucco/type exterior.  Their water dissolved the exterior surface and leached/removed the minerals there.  Once in the rinse water they ran down the large plates of glass directly underneath.  Then when the water evaporated these minerals locked onto the windows.  Granted there could very well have been other factors involved here that I still don't know about.  But what I do know is when I asked what was used all I heard was, "just water".  This was an older building, it was all rented out, the owners likely even heard about the problem;....but the stains are still there.  For me to experiment on.  With a commercial storefront route of about 135 customers I have many situations that I can exploit for educational purposes.  Sometimes I just whip out the machines and chems and go at it.  No one even pays attention.

You know it really is quite ironic that the same water that we use to clean and maintain windows has the power and ability under the right conditions to do such damage to glass surfaces! Here is another totally fascinating example which I am sure you old timers have seen.  I am talking about storm windows.  Try this next time you do an old house with outer storms.  Once clean, run a dry fingertip lightly across the inside and then the outside of the upper storm window.  The inside will be very smooth.  But not the out.  That surface has been literally chewed off by a process called weathering.  I am going to get just a little technical here and go to one of my reference books, "Corrosion of Glass" published by Ashlee way back in 1979.  My point being we have known about this stuff for a long time.  Really nothing new.  So you really don't have to take my word for it.  I just pretend to be smart.  But am actually just connecting the dots here!  OK.  So the book says on page one of chapter one;...."Stage 1: the initial or primary stage of attack is a process which involves ion exchange between sodium ions from the glass and hydrogen ions from the solution...".  This book also states on page one of chapter one;...."Stage 2: the second stage of attack is a process whereby breakdown of the silica structure occurs and total glass dissolution ensues.".  The Glass Committee of the IWCA under the leadership of Paul West became aware of this chemistry and how it actually promotes certain chemophysical changes in soda-lime window glass.  Several points are of note here but I would like to draw your attention to the fact that hydrogen ions (which come from water) are quite involved in promoting the initial Stage 1 reaction which ultimately leads to Stage 2 which is in fact "total dissolution" or breakdown of the glass surface.  In much simply terms water eats glass.  How quickly and to what extent depends on various conditions such as relative humidity and temperature.  All of this science should convince us and our customers that glass should be sealed with a product.  My preference is Nanovations NG1010.  You will find more information and video demonstrations of this product elsewhere in this blog.  If you have any other questions about it just ask.  Here is a picture taken from the above mentioned book demonstrating total dissolution of glass in the furrows of some scratches.



Next up are interleaving systems for the on site storage of window glass at new constructions.  The idea is that water or humidity (especially in hot climates) can easily over time cause corrosion of glass plates.  This problem is made much worse when we consider that the glass could be placed in storage for as much as six months before installed on the building.  So the simple solution is to keep the plates from getting too close together.  You see glass naturally loves water.  Therefore when moisture condenses between two plates that are very close it doesn't evaporate.  Over time the chemical reaction described above takes place.  Dissolution occurs.  And the window glass is damaged.  Here is a link to an online article written by Dr. Paul Duffer on precisely this problem and how to prevent it.  http://www.vitroglazings.com/VitroGlazings/media/sitedocuments/TDs/19_TD105F.pdf  Dr. Paul has been a tremendous help to the IWCA for many years devoting so much of his time.

Another very interesting condition involves what I call water lines.  I have one job in particular where these have formed on the inside over many years.  They are difficult to see on cloudy days.  Also difficult to see from the inside looking out when they form on the inside.  But are very easy to see from the outside looking in when formed on the inside and on a bright sunny day.  They result from water running down the window constantly.  The water chemically wears a path.  Hence each water drop precisely follows the path of the previous drop.  Eventually this process creates dark lines.  They can be removed by various polishing processes.  Such as wet diamond compounds and soft but small polishing pads.

Failed IG Units are a perfect demonstration of a stage two static etch.  This type of etch forms on the inside of insulating glass units.  It usually takes many months to form.  But it is a perfect demonstration of a static etch, not a dynamic etch.  Water vapor or moisture collects between the plates as the seal fails. But it cannot easily escape.  So it remains there, and heats up very quickly in the hot sun.  Which causes the reactions discussed above.  Although the reaction byproducts are not removed by dynamic/flowing water.  So such salts are not removed.  They just stay right there.  It is easy to see when this happens.  Because initially the condensed moisture is completely clear.  Then as the reaction begins you will notice a white cloudiness develop.  It will not be even but rather shows up like clouds.  Also it starts as a very light cloudiness but becomes more and more opaque.

Phobic 2 Phylic Video Part Two

The purpose of making this video was threefold.  First my intention was to show off the Mini-Wobble.  I wanted to show how much like the six inch Wobble Wheel it is.  That it has a swivel feature which allows for a 12 degree variance of the drive shaft.  This permits the polishing disc to remain perfectly flat on the glass at all times without bobbing around.  So as to minimize the polishing learning curve.  It is so easy it can be used with one hand. just like the six inch Wobble.  Further when the wheel remains totally flat on the glass this also greatly helps to minimize and scratch haze.  The preferred method of polishing is with a soft polishing pad.  Felt also works.  Except Marc Tanner does not like felt.  And he is the expert in this field.  For this reason Marc and I along with Dave Keller are working on a very special high tech pad developed especially for one step polishing.  As for the polishing compound I prefer a rather thick cerium based compound.  This along with a "not hard" pad works very well.  And I will be making another video very soon to demonstrate the most efficient way to work with cerium.  Which I think you will find very practical.  Here is the video I have written this post about.

Second my intention was to demonstrate the Slow Release (SR) pads that are being sold by Universal Photonics.  I developed the term Slow Release.  It is more of a generic term.  There are other commercial pads which use similar technologies as this one.  Universals name for their pad is the Phantom Fixx.  Their Product Customer Part Number is PFPD050010A01A01.  I used a two inch diameter pad with a Velcro backing for the video.  The address for Universal is 85 Jetson Lane, Central Islip, NY 11722.  Phone 516-935-4000.  www.universalphotonics.com
This test I did was very interesting because the pad was rather hard.  Especially compared to the ones that I created using a special PVA density powder and another softening ingredient.  Both the Phantom Fixx and my SR pad had the tendency to leave visible scratches on certain surfaces.  The Phantom Fixx did not leave any scratches on the mirror at SuperCuts.  It also did not leave any scratches on the very last test on the outside of the window at the garage.  But absolutely did leave scratches on the inside of the garage windows.  Which did demonstrate that it is absolutely NOT a pad that can be used on every glass surface without causing any problem.  If you chose to use it you must be extremely careful.  Also you must never use it on a tin oxide low e surface.  These surfaces require exceptional care.  Universal does have many other excellent products that we can make compounds with.  I have received three different ceriums and a zirconium oxide that I will be testing.  I also have a couple premaid diamnond compounds which I bought from another company that I will be testing.  And of course they will go on the Glass Smart YouTube Channel.

The third and equally important reason for this latest video is to demonstrate how easy a Phantom Fixx pad very efficiently converts a phobic surface to a phylic surface;...every time!  This is also a very long lasting change.  It also does not create a mess from loose compound.  Hence the cleanup is very quick.  Just soap and squeegee.  This type of "deep clean" using such a "quick" polishing technique is also very useful for applying a hydrophobic sealant like Nanovations NG1010.  What I have also found very interesting is that truly hydrophylic surfaces allow anyone to snake off a window or mirror using just plain water.  Who would have thought that you could swirl any plate of glass with pure water?  No chems, no soaps at all!  I thought it was very interesting too that when you wet a completely phylic (water loving) glass surface with water it sheets over so efficiently that the surface looks completely dry.  This is the surface which we want for Water Fed Pole work because the rinse water will drain off leaving no spots.  No drops no spots.  It also makes it possible to clean very fast with a WFP.  This is something I will be demonstrating too;... IN THE FIELD. 

This is all just the very beginning of this new technology.  It will completely revolutionize WFP work.  This IS a technology.  But it is a technology which will be fueled by and driven by some very innovative products.

Testing Solvents for Non-Conventional Window Cleaning


If this direct link does not work on your phone you might have to go directly to the Glass Smart YouTube Channel


This is the latest GS YouTube video just completed on June 1st 2019.  Hope you enjoy.  On it I have put to the test four different Solvents.  The Clean 1000 and Clean 1200XA from Elevance and sold by J.Tech Sales of the Maroon Group in Boca Raton Florida.  Also the Augeo Clean and Omnia product sold by the same company.  The video does a good job at showing which works at softening and dissolving paint.  Specifically Krylons Industrial Rust Tough spray paint.  I chose fluorescent green.  What you can't see on the video is the smell.  Most people will not like it.  But then most don't like the smell of Titans Oil Flo which is based on a different chemistry.  The Clean 1000 and Clean 1200XA products have the most strong odor.  Whereas Omnia and Augeo are not so bad.  Of these four the Augeo is the least effective at softening paint.  It is based on the chemical isopropylideneglycerol.  As for the Clean 1000 and 1200XA they are based on methyl 9-decenoate (9 decenoic acid methyl ester).  Also Eastman Chemicals' Omnia is based on butan-1yl-3-hydroxybutanoate; butyl-3-hydroxybutyrate.    Here are some links to the Material Safety Data Sheets for these products.  I could not find the MSDS for the Elevance Products online.  But the contact information for Elevance is;

Here are some links to the Material Safety Data Sheets for the Omnia and Augeo.  

Omnia  http://ws.eastman.com/ProductCatalogApps/PageControllers/MSDS_PC.aspx?Product=71093918 

Augeo  https://cdn.shopify.com/s/files/1/0153/9461/files/AUGEO_CLEAN_MULTI_-_SDS_surfachem_0603818.pdf

As for purchasing or obtaining samples of any of these four solvents you can contact;... 

JT Sales 6531 Park of Commerce Blvd Suite 170
Boca Raton, FL 33487
USA
561-995-0070

As you can see from the video small specks of paint can be removed using all of the solvents.  Although if you have a rather thick coating of paint the products of choice would likely be the 1000, 1200, or the Omnia.  These products can also be blended with a product such as Composition Materials Plasti Grit line.  More specifically their Clear Cut 200 Grade.  Their contact info for purchases and samples is;...

Composition Materials Co., Inc.
249 Pepes Farm Road
Milford, CT 06460
Ph 800-262-7763 ph 203-874-6500 Fax 203-874-6505

The Clear Cut is a plastic abrasive with an acrylic particle.  The powder cuts through greasy fingerprints with extreme ease.  I am sure you will find other uses too in nonconventional window cleaning.  

I discovered the most effective way to use the solvents was to coat the painted surface for about 45 minutes to an hour.  Then you will be able to wipe the paint right off.  Soap the window and squeegee.  To enhance this effect and keep the solvent from evaporating you could apply the product to the window and then apply a thin sheet of clear plastic over it.  Which you should be able to get at most any hardware store.  Then while you are waiting on the solvent to work you could be cleaning other windows.

The Secrets of Developing the Absolute Best Pads for Polishing Glass

Everyone is so focused on compounds, slurrys, and commercial polishes that most have disregarded pad tech.  This is a big mistake.  Because the type of pad is critical to the desired result depending on what type of surface we are working on and the identity of the problem.  Every job is totally different from the one before.

There are felt pads, synthetic felt, urethane foam, and many other materials that have been used.  The reason for the different pads is the difference in their properties.  For example felt pads are made from condensed natural hair fibers of different sizes, thicknesses, and densities.  Such fibers have the tendency to grab onto and hold the polishing particles such as cerium, silicon carbide, or silica.  Synthetic felt is similar in that the fibers are made from polymers.  They are not natural hairs taken from animals.  But the properties can also be different.  Now different polymer foams like urethane also differ in density.  Which is not density of the fibers but rather density of the polymeric foam matrix.  The difference in density here will change how quickly the pad generates heat depending on how fast it is spinning, or the rpms.  It will also determine how much heat it can withstand and still maintain its shape or flatness.  Why is this important to the polishing process?  Simply because heat and friction are critical to the overall performance of the polishing compound/slurry.  Attaining the correct numbers without changing the flatness or density of the pad over time is very important to clearing the glass in the least amount of time.  All of this must be taken into consideration when designing pads to be used with cerium oxide, silicon carbide, microcrystalline silica, aluminum oxide, and even diamond.  It is also necessary to take this information into consideration when designing pads for different surfaces.  Of course there is a large difference between glass and acrylic or polycarbonate.  But there is also a great difference between clear glass, dark glass, and the tin oxide surface of low e hard coats.

Currently Marc Tanner and myself have begun working with Dave Keller who has retired from a long carrier with Universal Photonics.  He has many years of experience traveling all over the world working very close with the optics and electronics industry.  Now he has formed his own company specializing in developing and selling polishing pads for various industries including the same.  Marc Tanner is in my opinion and the opinion of many others in the glass restoration world the absolute best at what he does.  His experience is nonpareil.  It is with great excitement that I am now telling everyone that I am expecting some great products from our research.  They will be sold through Kellerco which is Daves' new company.  I will keep you all updated through the Glass Smart Media.  That being this blog, the Glass Smart FB Group, and the Glass Smart YouTube Channel.  So stay tuned.

Protection Products

There are many different types of glazing surfaces out there.  There is glass, low e metallic coatings, mylar/polyester, plexi/acrylic, and lexan/polycarbonate.  All of these can be destroyed by concrete, stucco, mineral deposits, silicone caulk, silane sealant runoff, paint, wood stain, and much more.  Once these get on the window it becomes very difficult to remove them without scratching or doing other harm to the surface.  Therefore the best way to handle this problem is to protect the surface in my opinion before the windows are even put in storage.  Which is done sometimes months before they are installed in the building.  Damage can be done to the windows even at the factory where they are manufactured.  So it is good to have them properly inspected when they arre at the construction site and then protected with a protection product before they are placed in storage.

There are two basic protection products.  Permanent and temporary.  Permanent products are usually wipe on sealants such as Nanovations NG 1010.  Those which are temporary are strippable brush or spray on coatings that are easy to peal off at the time of cleaning.  Other temporary products are films that are self clinging and are applied as sheets.  At the time of cleaning such films are pulled off.  Sometimes you might get a static shock when doing this.

Since there are so many different surfaces, with different contaminants, and different protection products;...this is truly a technology.  It requires much testing in the lab.  But also in the field.  So I always recommend field testing at least a patch of one window and trying out some concrete or paint to see if it is going to work.  Glazing surface protection before, during, and after construction should always be practiced.  This is a technology that every window cleaner that does post construction work should learn.  But it is not window cleaning.  Just like restoration work is not.  

Here is a short video of one protection product which is a brush on strippable coating.  I will be preforming many other tests on this product and putting them on the Glass Smart YouTube Channel.

Protecting Pilkingtons Energy Advantage Hard Coat

Energy Advantage is a tin oxide low e hardcoat which on occasion is used as a first surface weather side product.  Whether it is the weather side of an insulating glass unit, or a monolythic plate, it is exposed to contact.  This means that any type of construction debris can get on it.  The problem then becomes one of safely removing the debris.  Since we cannot use razor blades or in my opinion not even steel or brass wool, there is a serious problem of exactly what to use to clear/clean such a low e surface.  So I am currently developing products which can be safely used.  But another solution is to use some type of strippable safety film that can be applied when the window is clean.  Then stripped off afterward once the window collects paint, stain, silicone caulk;...or whatever.  I have discovered a product called Windocoat which works very good on glass.  But did not know whether it would also easily strip off a Pilkington Low e tin oxide hard coat.  Of course there is only one way to know.  That is to do the test.  So I did.  Here is the video I did of the test which I just published a couple days ago on the Glass Smart YouTube Product Development Channel.  Let me first say however that I always suggest doing a "patch test" with this product on any surface before painting an entire building with it.  Never leave it in doubt.  General Chem the sales company, have told me that they didn't know if it would stick to a low e surface or not.  Well check out the video and tell me what you think.  There will be many more short videos to follow.  So please go to this YouTube Channel and subscribe.
