Beta Testing Poly-Skrub

 Poly-Skrub is a plastic superabrasive powder.  The particles are much larger than those used in glass restoration products.  But since they are based on a plastic they are softer than glass and most metal coatings.  So they will not scratch but are very effective at "chewing" through paint, silicone caulk, and would stain.  These particles have an angular cut to them, and they are rather effective at standing up to different organic solvents such as paint thinner/stripper.  So PK can be blended with solvents.  and since this plastic has a specific gravity very close to water they can be easily kept in suspension.

One test I suggest doing is based on this idea of particle suspension.  It can be mixed with a solvent such as Oil Flo, or another product like a hardware store paint thinner.  I have experimented with a fifty/fifty solution of PK and a green paint thinner.  It stayed in very good suspension.  After a day it will settle out.  But all I needed to do was shake the jer for five seconds to bring it back into suspension.

I have also experimented with a paint marker.  Then simply wet a cotton terry and dobbed the dry PK powder, then I rubbed the dry marker line.  I did a side by side by first rubbing with just water.  The water did nothing.  But the PS removed the paint completely.  The paint thinner/PS combination is more effective.  Since it has the best of both worlds.  That being the chemistry of the solvent and the abrasive properties of the PS.  

IGSA has discovered too when it is used in the same fashion that it is actually effective on Low E coatings.  It will remove abrasion marks from metal implements such as car keys.

We have also had success when doing water fed pole work by sprinkling the PS powder on flat scrub pads.  With several passes of the WFP pad the PS powder gradually falls off the glass.  It is very effective at removing bug poop and other relatively difficult things.

You can also take a white pad, wet it with sodium water, and apply the powder to the back side.  The powder will actually move through the pad from the back to the front.  It is rather effective when used along with the white scrub pads. 

So there are many different ways it can be used.  My big idea right now is to use a double sided piece of tape and sprinkle the PS powder on one side.  Then apply the tape to a doodle bug tool or one that has been designed for WFP work.  The powder should stay stuck but will help in removing whatever needs to be removed.

If you would like to become a beta tester for this product and many more different products just send me an email.  We also have a FaceBook Group for IGSA Beta Testers.

Be A Beta

 IGSA was established for the dual purpose of education and product development.  Anyone who has been reading this blog knows how focused on research and education Glass Smart is.  But education without products to practically solve the problems in our everyday work is useless.  Therefore IGSA is also focused on developing new products for non-routine window cleaning.  It is likewise focused on developing products further that have already been developed and are currently on the market.  Whether the products are new beta products or already existing products;...testing by smart window cleaners is critical to development.  This process desperately needs to be interactive.  It is for this reason that I am now working on creating an IGSA FaceBook Group.  I will let all the subscribers of the Glass Smart Blog know when it is done.  But you can still participate right now if you would like!

There are many products we need to test that have already been developed.  Several of these the window cleaning industry doesn't even know about.  But there are also many products that have yet to be developed.  Currently IGSA is working on a line of different plastic abrasive powders.  The first one available for testing right now is called Poly-Kleen.  I am making this available for just 20 USD to cover my own cost and time.  All you have to do is send me your email address, your name, and a full shipping address.  I will send you a sample and a bill by PayPal. I am looking into Apple Pay and Venmo.  But currently the two options are PayPal and a check by snail mail.

Fluidic Art for Your Office

Everyone needs just the right kind of art for their office.  And most do like what is called Abstract Art. Fluidic is a special sub category of Abstract. It was discovered back in the 1930s by accident.  My wife and I just discovered it, and have become self taught in how to create pictures on canvas that can be easily hung.  Here are several of them.

Should you want to purchase any of these or see what we have created at any time just go to  Each is one of a kind.  An original.

Beta Testing Poly-Skrub

 1/2 Pound of Poly-Skrub is available to anyone who would like to become a member of the International Glass Smart Association (IGSA).  Just 20 USD covers the cost of having this shipped to you anywhere in the US.  There is no cost to become an IGSA member.  Just your participation in testing IGSA products.

The first test should include low e coated windows.  Peter Thomas had very good success using a car key.  He made up a compound of PS and water.  Then rubbed the "scratch" with a soft cloth.  And cleaned with a bit of citric acid.  The scratch or abrasion vanished.  My suggestion is to do like Peter did.  Use a sample piece you can throw away.  Not a customers window.  Unless the damage is already there and someone else caused it.  And you have permission to do a test.  Which permission might be verbal or better get it in writing.

Nick Evans has discovered PS is very effective at removing the residue from artists paint.  Most times a blade only removes the heavy paint.  But leaves "color shadows".  He will take a plastic scrub pad, wet it, then put the PS powder on the inside of it, and fold it over with the PS inside.  The PS actually moves through the scrub pad as a paste.  In this way you have better control over the amount of PS used.

Another test will be blending PS with different solvents like toluol, xylol, DLimonene, other essential oils, different paint strippers, or other specialty organic solvents.  The idea is to make the most of the plastic superabrasive and the softening chemical power of the solvent.  I did try PS with pure water and discovered how it was able to remove cured paint marker.  The video is in the Glass Smart YouTube Product Development Channel.  

Another test involves making a simple sandpaper using PS instead of sand.  Then the particles can be captured on the paper and will not be free to get under the squeegee rubber.  When they do this we end up getting lines as we squeegee.  It also allows us to put the solvent straight on the glass and wait for it to soften the paint or something else.  Then when the time is right we just hit it with the "sand" paper.  The PS Paper.

What makes PS so unique is that it is a plastic superabrasive and is such much softer than glass.  It also is very resistant to various solvents.  The particle distribution curve is very tight.  The particles are much larger that cerium oxide which is used to remove scratches.  So it is much more effective at chewing through things like silicone caulk.  These particles are also sharp because of the granular process needed to make the powder.  Which is also rather resistant to chemo/stress cracking.  They are also much softer than glass so as to help prevent scratches from from particles like silica or silicates that have the same hardness of glass.

Do not expect that it will work well at removing mineral deposits.  This cannot be expected from its previous properties.  But it is very versatile for precisely the same reasons.

Again if you would like to become an IGSA beta tester starting with Poly-Skrub just send me an email with a snail mail shipping address.  Then I will send you a sample the very next day and a bill for 20 dollars.

Next Gen Window Cleaning

We all know that the days of the bucket, mop, and pole are gone.  Even when we are doing trad work we cannot avoid problem surfaces!  Bad glass, frictive glass, coated (reflective, low e, antireflective) glass, solar (mylar) film, acrylic, polycarbonate, and the list goes on.  When any of these different surfaces become contaminated with paint, wood stain, urethane, silicone caulk, concrete, stucco, concrete sealer, hard water spots, etc.; we enter into what has been called non-routine window cleaning.  This can present whether or not we are engaged in trad work, WFP work, or specialized restoration or preservation work.  There really is no limits on how risky our line of work has now become.  Coupled with the fact that we have a host of different manufacturers of products that will etch, scratch, and otherwise do irreversible damage to these different surfaces.

In the old days glass was glass and nothing more.  But not any more.  We now have an entirely new business.  Next gen window cleaning.

Super-Abrasive Plastic Powders

 IGSA has just developed the first super-abrasive plastic powder/product for non-routine window cleaning and coated glass restoration.  It is based on polymeric particles which are measured in microns, softer than glass, and have an angular shape.  These particles also have a different chemical functionality.  This means simply that their surfaces have a different chemical identity than cerium oxide, feldspar, or silica.  Which will react differently when in contact with glass, titanium dioxide, or another metallic alloy.  These differences will result in different effects.  

For one thing it should be possible to use particles that are larger than those used to polish glass.  This will allow for the quicker removal of contaminants like cured silicone caulk.  It can be mixed with various solvent blends too for quick removal of paint from defective glass or coated glass.  Recently Nick Evans of New Zealand, the chief founder of IGSA, proved that our first product Poly-Skrub is very effective at removing greasy residue from etched glass.  Also Peter Thomas of Australia has demonstrated that Poly-Skrub is capable of removing car key scratches from a low e coated glass surface.  We will be testing this product on many other coated glass surfaces and defective glass too.  Really we are just beginning to learn about all of the different applications and benefits of this product.  Here is the video I made showing Peter Thomas discovery with car keys.

If you would like to try PS yourself just send me your email and shipping address.  I am sending out one pound for 20 USD plus the shipping cost by PayPal.

Coated Glass Can Be Restored


So most people think that Low E Coated surfaces cannot be restored.  Well we here at IGSA beg to differ.  Check out this video featuring Peter Thomas from Australia.  Using our first product/ingredient he will show you how quickly metallic Low E surfaces can be restored.  There is so much more to learn about working on Low E!  You will get it right here on the Glass Smart Blog, YT Channel, GS FB Group, Instagram and other social media featuring IGSA Products.  Poly-Skrub is a one of its kind product.  A superabrasive plastic powder.  Available in powder form so it can be used to create a variety of solvent based compounds for removing construction residue from defective glass surfaces, and Low E surfaces.  It can be used as an additive for other compounds too for added power.  You be the creator!  Want to be a member of the International Glass Smart Association (IGSA)?  Just send me an email.  Copy and paste my email.

Can We Abolish the Razor ?

There are three different types of surfaces that a metal razor absolutely cannot be used on.  There are other surfaces too.  I am just focusing on these three in this post.  To directly address the question raised in the title of this post I need to say very straightforward;...NO!  I do not believe we can accomplish this.  I really believe there will always be a place for razors in window cleaning.  However it is becoming more and more difficuly to use a razor safely.  For reasons that will become very obvious in this post.  It is therefore critically necessary that we learn how to identify these surfaces and discover and develop products that can be used safely on these different surfaces in place of the metal razor.  Such as micronized plastic abrasive powders.  Which I am starting to develop and show in videos on the Glass Smart YouTube Channel.  Which you can subscribe to.  Right now!  The link is below.  PLEASE subscribe.  When enough people do that I will get more benefits that will help me to help you.

As it stands right now the float glass manufacturing industry is putting out glass products worldwide that have defective surfaces.  Surfaces which we absolutely cannot use a metal razor on.  Check out these two videos which plainly demonstrate what defective surfaces sound like.

This is a very common defect that is usually found on at least one side of most tempered glass.  The sound varies because the density and size of these aluminosilicate embedded particles differs from one plate to the next.  When the psrticles are dislodged and dragged by a metal razor the particles scratch the glass.  Not the razor.  Nonetheless the pattern of the scratches tell more about the identity of the particles too.  Meaning the size and density.  Listen close to the sound in these two videos.  You will learn that the particles are not very dense and are of a variety of different sizes.  I used a penny in these videos.  I would never use a razor.

Another surface we would never want to use a razor on is coated glass.  That being TiO2 (low maintenance), antireflective coatings on solar panels, Low E reflective first surface or inside surfaces, mirrored surfaces, and many other metal coats.  For whatever the reason metal blades cause scratches either directly or indirectly.  Metal surfaces are becoming almost invisible.  So they are very difficult to ID.  So I made a couple videos to show how simple it can be.  Not always.  But many times.  Check it out.

Yet another surface that metal razors cannot be used on are plastic films and glazing materials.  That being mylar solar film, acrylic surfaces, and polycarbonate surfaces.  Plastic is all around us.  I mean everything is plastic.  And yes I have scratched acrylic and polycarb with a blade before too.  I have also used a blade on some really pricey mylar solar film and almost had to change my pants when I found out what I had done.  Just collected my check and hoped the customer did not see any scratches when the sun came out the next day.  I was not able to see any that day.  Fortunately I never got any calls.  But.  My point is this.  ANYONE can make these mistakes at any time.  So we need a simple, quick, nondestructive testing method to determine if a window has any type of plastic film or plastic surface.  So we DO NOT use a razor.  Here you go.

So there you have it.  The only surface I have not touched on yet is frictive glass surfaces.  But I will.  The point I am trying to make here is we MUST be more aware of the different surfaces we are working on.  So that we do not lose our businesses.  No one wants to pay out thousands for replacement glass.  And no one wants to have to deal with a sickening lawsuit.  But something else is going on here.  Something that is much bigger than even this.  PAY ATTENTION PLEASE.

I have about a hundred stores on my window route.  Twenty of these are restaurants.  All independents.  They are more frequent, pay more, pay fast, and usually pay cash when I am done.  Restaurants are closing up now.  It might be that those of us that rely on route work will have to change to a residential customer base.  But not just any residential customer base.  One with big paying wealthy individuals.  Then this kind of knowledge as I have demonstrated in these videos coupled with high tech specialty products that I am currently developing will be invaluable.  Use these videos to sell to this group of potential residentials.  No Wendys, or CVS, or Dunkin Doughnuts is going to care about scratched or acid damaged windows.  But a wealthy homeowner with a multimillion dollar home will!  Yet you have to SHOW them.  I have now done what I told you I would do.  I have put that power in the palm of your hand.  Just take out your cell phone and play them the one to two minute video.  Go to the link below and subscribe to the videos you have watched above.  I will be making many more. Currently I have about 18.  So you will receive a link to each one when it is published.

You Too Can Be A Consultant;...Seriously!

Over the last 25 years I have been called in to consult on buildings by window cleaners, janitorial companies, construction companies, real estate companies, lawyers, property maintenance management companies, and even insurance companies.  This has made me more money in a day than I have made cleaning windows.  But in only a fraction of the time.  I have always believed that many other window cleaners could do the same thing.  And I would like to help you become a consultant too.

I learned much of what I know by using brand new glass samples.  For example what of the different types of etch that are caused by different acids?  What acids do not cause etched glass?  To come up with the answers I literally wasted window glass and took it to the dump.  Then when I seen different conditions in the field I knew immediately what I was looking at.  Sometimes I would see certain conditions out there that I surmised were caused by acids, but didn't know.  So I went back home and used the sample products and chemicals that I had there to duplicate what I seen in the field.  Once I succeeded I had the answers that I needed.  A case in point was a building down in PA.

The building had two different conditions.  It had a kind of clear orange peal effect.  Also a clear banding that followed straight up and down.  The building had been sealed with a liquid siloxane concrete waterproofing sealant.  Which ran down over the dark glass.  It also was covered with hard water spots from concrete efflorescence.  The kicker was the sealant ran down the glass and so it was removed simultaneously with the hard water spots with a hydrofluoric acid based "restoration" product.  As it turned out the acid had eaten into the glass showing the pattern of the banding from the siloxane sealant and the spots which showed up as a clear orange peal.  There was no clouding but both the moderator and builder matrix of the dark glass had undergone complete dissolution.  So I went back to my little makeshift grassroots lab.  And was able to easily duplicate both of these conditions using both the restoration product that was used on the building in PA, and a pure water based solution of 1 and a half percent hydrofluoric acid.  I was first called in to look at this building by the restoration company that was looking to come up with some way to "fix it".  There was no fix.  Then I was called in by the company that did the damage, the insurance company they had, and the lawyer that the building owners were using. I actually demonstrated how easy it was to cause the damage using this acid.  Each time I was called in I was paid.

There were many other consulting jobs that I was called into over the years.  Which I will talk about on this blog.  I think if anything you will find them interesting.  At the same time it will lead you into how IGSA will be making courses available to help train our members to become consultants too.  Hope you find it enjoyable.

The Destructive Power of Defective Glass Surfaces

 Defective glass is very easy to scratch.  But not as easy to identify.  Simply because the scratches can be so small that they can only be seen in the direct sunlight at just the right angle.  Or they can be so large that they can be seen at night with a dim flashlight.  This is very simply because the size of the ghost particle is learned by the depth and size of the scratch.  The number of ghost particles is also determined by the number of scratches per square inch or as I like to say the scratch density.

It is very easy to mistake frictive glass surfaces for defective surfaces.  This is because defective particles can be so incredibly small.  As small as nanometers.  I have included here an example of 50 nanometer sized aluminum silicate particles.

Here is an example of just exactly the type of scratch I am talking about.  These were created by a short four inch edged razor.  I took the picture with my IPhone in the direct sun.  Gotta love these phones and digital technology!

Frictive glass can be quite rough and yet show no scratches when a razor is used.  I know this is counterintuitive but I have observed it.  Then there exists defective glass with ghost particles so small that they feel like frictive glass but do in fact cause scratches from a razor.  Now with this being said we should not get the idea that frictive glass is not totally safe.  When we polish glass to remove hard water spots with a cerium oxide slurry we end up creating a frictive surface that will scratch much easier than most glass surfaces that feel very smooth with a penny.

Admittedly this discussion can be rather confusing.  But i think all that is required is the reader to spend a few years cleaning glass for a few years to know that all glass is NOT the same.  There is a great difference.  Sometimes on the same plate!  Just beware.  Defective glass is more abundant now then it every was.  And it is waiting to cause a lawsuit.  You do not want to have to face such a thing.  Your insurance will not cover it.  And it could destroy your entire business.

The Insider, Establishing The Structure Of IGSA




 Poly-Skrub an IGSA Product Line

The very first of this product line, and the first IGSA product, is a dry plastic powder.  It was developed exclusively for hard metallic coatings such as TiO2, frictive glass surfaces, and defective glass surfaces.  The idea behind its creation was to locate a plastic particle that was small enough, had the correct shape, and was softer than glass and low e, and antireflective coatings.  The purpose is to be able to remove paint and other debris from such problematic surfaces without leaving scratches.  So it is NOT intended to use on every window.  In order to increase the effectiveness of these products I am currently tesing Poly-Skrub with different solvents.  Some of which are on the market.  The idea here again is to not scratch glass.  When you join the best of both worlds (solvents and soft but course abrasives) you end up with custom products that are much more effective at removing paint, wood stain, etc., without creating scratches on frictive, defective, or coated glass.  I have demonstrated here in this video how effective Poly-Skrub 1 is at removing paint using only soapy water.  By using a soft cotton cloth soapy water does not even budge the paint.  You can see here how it doesn't even come off the glass just a little.  Which would show up as a very slight red color.  But using the same effort, the same time, the same cloth, the same soapy water, but a buff of PS it is quite possible to scrub off the paint.  Can you imagine how much easier it would be if you were to add the correct solvent?  That is the direction that I am going with this.  My future videos featuring the Poly-Skrub Product Line will demonstrate the effectiveness of adding specific organic acids and organic solvents.  Also I will be looking at different ways of building compounds based on these abrasive powders, and affixing them to scrubbing pads that can be attached to our poles for high windows.  This will dramatically reduce the amount of powder needed for the job.  Which will also allow us to use much higher "tech grades" of plastics.

I have written many posts on the science of particles.  But have focused mostly on cerium oxide, aluminumoxide, silican carbide, silicas, and others.  Not plastic particles.  But the truth is that plastic particles will likely prove to be a large part of the answer we are looking for when working on "glass sensitive" window surfaces.  When searching for a specific plastic particle/powder I am looking at hardness (glass and low e surfaces are rated 7 Mohs), particle size, particle distribution curve (PSD), chemistry (for solvency resistance), and morphology (is the particle round, oblong, cubic, or amorphous?).  All of these properties will affect the overall performance of the product.  Lets take size as an example.  Very small particles will not chew through paint very well at all.  But they are very effective at eating up almost invisible thin residues of cured silicone caulk.  Very large particles are rather effective at removing globs of silicone caulk and even shot gun fungi.  The only real way to know what works best on what is to do the test.

Particle science will always play a very large part of the products that IGSA brings to market.  What is also going to be very exciting about these products is that the affiliate members of IGSA will be able to assist in developing these products as IGSA beta testers.  If you would like to participate in this and want to become an affiliate or even an IGSA distributor please just send me an email.  Distributors are now being given certain territories.
