A Very Exciting Gift for the IWCA 2018 Convention

This is a very very special post and my gift for the 2018 IWCA Convention in Florida.  I will be telling you things in this post that I haven't told anyone else.  Things I am quite sure most manufacturers would love to know.  Because as much as we might not think it, these manufacturers like Unger, Ettore, Moerman, Sorbo, and many others really do have their finger on the pulse of our industry.  Especially the Water Fed Pole industry.  Don't be fooled my friends.  To put it quite bluntly they are not stupid!  They know that we have been searching for the Holy Grail of WFP Window Cleaning.  I will be explaining what that is exactly in very precise words.  Further, and this is the real big one, I will introduce you to the company that will open the floodgates to this technology.  The time is NOW!  So read on.  And please share these words with one another at the convention this year.  I only wish that I could be there with you.  I really really mean that.

What exactly IS the Holy Grail of WFP work?  NOT what you would expect.  Perry Tait claims that he has a special brush capable of making glass hydrophylic (water loving), but only for the time it takes for the water to sheet off the window.  He has even posted videos to demonstrate.  This shows that Reach It is very much aware of what we are looking for.  Further it is true that scrubbing the glass with bronze wool will convert hydrophobic glass to hydrophylic.  I have done it with white scrub pads too.  I have also done it using compounds based on microabrasive compounds like silica and cerium oxide.  I have developed slow release coatings that are water activated which will do the same thing.  But all of this is NOT the Holy Grail.  There are products based on glass etchants that when applied to glass almost instantly etch the glass, turning it from hydrophobic to hydrophylic.  I would never suggest using these under any circumstance however.  But no friends, these are also NOT the Holy Grail.  There are surfactants used in agriculture which are called Super Wetters that will lower the water surface tension from 72 down to 20 dynes.  These will cause your rinse water to completely sheet over a glass surface that has been treated with a hydrophobic coating such as Rain X, Aqaupel, Enduro Shield, or the one endorsed by Marc Tanner, Nanovations NG1010.  Never mind just plain old hydrophobic glass.  They do this at only .01 percent.  The rinse water drains off the glass leaving absolutely no spots when done the right way under the right conditions.  But they also are NOT the Holy Grail.  There are coatings too that will bond to glass making it hydrophylic.  Then even high TDS water will sheet over the glass and drain off leaving no spots.  But they are NOT the Holy Grail.  Do you really want to know what it truly IS?  Very simply it is all of these except for any product based on a glass etchant.  It is the unique combination of these different answers according to the conditions we are working with at the time. This requires knowledge and understanding of this technology.  Which I call the technology of hydrophylic water fed pole window cleaning. 

To simplify there are three basic components that must be integrated into a whole solution which IS the Holy Grail.  Number one is to physically deep clean the glass so that the true hydrophylic surface is exposed to the rinse water.  Number two is to add just the right amount of the "correct" superwetter/surfactant to the rinse water to reduce the surface tension to aproximately 20 dynes.  Number three is to apply an additional chemical to the window that will coat the "activated" glass surface with a hydrophylic polymer.  So physically deep clean, use a superwetter, and coat with a hydrophylic polymer.  There it is in one sentence.  

Now to introduce you to the company that will help to open the floodgates to the Holy Grail.  Here is a link to the company website.

Siltech Corporation Logo

In their own words "Siltech develops, manufactures and markets a full line of organo-functional silicone compounds and related specialties for specific customer applications, using our patented as well as proprietary technology. With more than 25 years of experience, our expertise includes  organo-modified silicone surfactants and silicone polymers, including a full line of catonic, quarternary and di-functional silicones, as well as a number of reactive silicones. In these fields Siltech owns more than 30 patents.".  Why is this so important?  Simply because silicon based chemistry is the means by which many specialty coatings for glass including both hydrophobic and hydrophylic treatments have been created.  Whether these coatings are organic or not.  Also the second and the third component to developing the Holy Grail relies on this chemistry.  Another very big reason why I know absolutely that this company will open the gates has to do with public relations.  A number of months ago I opened a dialog with one of the leading chemists that work for Siltech.  I have also had communication with others in the company.  It seams that everyone that works there including the owner and president are very humble and totally focused on customer support.  There was never any questions about sending out samples.  Never a charge for samples.  I was also told that they have plenty of resources to build anything that we wanted.  By we I am talking about the window cleaning industry.  Check this out. "Siltech has two modern plants, one located in Toronto, Canada and the other in Mississauga, Canada. Both plants are equipped with efficient, large-scale, high-temperature and pressure reactors, thin film evaporators and other modern equipment required in such unit processes as equilibration, hydrosililation, quarternization, amidation, phosphation, esterification, etc.
In addition to allocating considerable development resources to the refinement and optimization of production techniques, which have resulted in a unique processing technology, we at Siltech pay special attention to the changing technological requirements of the industries we serve.
Our R&D and technical service laboratories are modernly equipped and staffed by chemists with many years of experience in diverse segments of the chemical processing industry. In addition, we have efficient pilot plant facilities available to produce special products for your experimental needs."

Now you tell me, does that sound like a company that is willing to work with our industry or what?  I am getting shivers as I write this.  Literally!  I mean give me a break people.  The stuff that the Glass Committee has accomplished over the last eight years with Paul West and Dr. Paul Duffer leading us has been unbelievable.  This Glass Committee and the IWCA that we have now is nothing but incredible.  They are totally focused on the scratched glass issue and have devoted so much time to it.  Much more than myself.  All I do is write an article for the AWC.  There is another fantastic advance.  Since Michael Draper took it over that magazine has been turning out some of the greatest articles.  I have also been totally blown away by Lee Burbridges articles in the WCM, and am very happy to be a part of that.  What the Lambrinides have accomplished through their networking and the development of an inside community/forum that is now called the WCR Nation in such a relatively short time is nothing short of incredible.  This stuff was just NOT happening twenty years ago when I gave my seminars in Texas and Florida. 

So enjoy the 2018 IWCA Convention.  This is my gift.  Many more are coming soon.  Keep your eye on the Glass Smart Product Review.  And if you would like to receive these posts directly in your inbox just type your address in the box at the top right, "Follow by Email".

Explosive Profits With Nanovations NG1010

Nanovations Pty Ltd is a manufacturer of innovative product solutions.  It was founded by a group of  entrepreneurs in early 2000 and became one of the pioneers in commercializing Nanotechnology and advanced products in Australia. They claim they were the first company in Australia manufacturing and implementing Nano-scale glass coating technology. The first large scale building applications were done in 2004.  Again it is claimed that these coatings still work well and have never required a reapplication for the last ten years.
In 2006, the research in ultrathin coatings and the manufacturing of such was combined under the new brand Nanovations. The first high rise building in the world was coated shortly after, in Sydney, Australia.
In 2012 Nanovations introduced the next generation of automotive windscreen treatment which offers advantages over competing products, with better performance and functionality on today’s markets.  This product is formulated with an inorganic sol-gel technology.  They are currently exporting more than 95% of their products to more than 40 countries.
Again Nanovations Pty Ltd claims they are the only manufacturer of inorganic Nano scale glass coating technology in Australia. Nanovations has expanded into the USA through Nanovations USA located in Florida.  The contact information for this company is listed at the bottom of this post.
Consider this interesting piece of information.  The  SOCAR TOWER in Baku, Azerbaijan (check out the picture below)  was designed by the world leader in design, production, and installation of architectural envelopes and curtain walls, the Permasteelisa Group. Here is the link to their company. 

Further, Nanovations NG 1010 was chosen after extensive evaluation by glass laboratories in Europe, which indicated superior performance of this technology.  When you’re spending 200 plus million on a structure with a glass fa├žade, properly treating the glass surface is vital.  None of us would deny that!  Incidentally, the Permasteelisa Group was the engineering firm responsible for the curtain wall of the new APPLE Campus in California.  Both the SOCAR Tower and the Apple Campus would be of interest to all window cleaning companies.
When looking at the Nanovations coating technology the engineers likely were looking at ease of application, cost, stain resistance, coverage rates, scratch resistance, coating hardness, abrasion resistance, UV resistance (longevity), nanoscale thickness, and how easy it is to clean/maintain.   But.  You be the judge.  Just call them up and ask for a sample.  Then apply it to one of your accounts.  Show your customer what it will do.  I will be developing a line of very short videos demonstrating products like this.  These videos will come in handy when you want to pull out your phone and show a potential customer real fast what your company can offer.  They will help you make sales and dramatically increase your profit.  The Nanovations coatings such as their NG 1010 can explode your profits.  If you just simply get involved! Be a beta tester and tell other people through the social media we have available.  The WCR Forum and all the Facebook Groups.

A Dynamic New Way to Market Your Business !!!

If you would like to receive these posts directly in your inbox just type your address in the box at the top right, "Follow by Email".  You need to get this information as soon as it is available because it will change the way you do business and instantly increase your profits that day you receive it.  If of course you put it into practice.  When you do put it into practice you will have learned "A Dynamic New Way to Market Your Business".

The running theme title I have for the American Window Cleaner is "From the Lab to the Field".  The focus of this theme is the scientific study and application of information gained in the lab to field activities.  A case in point would be the study of how water and temperature affects the molecular species of soda lime glass surfaces.  Also how this chemical change affects how easily glass surfaces can become scratched.  It also affects how easily point indent fractures develop.  I call these PIFs.  Every scratch begins with a PIF.  To apply this to the field we need to look at the conditions of humidity in the field.  Windows in a very hot wet environment can easily become prone to scratches.  Also scratched glass can crack.  So the structural integrity of windows can be seriously flawed if for no other reason just because of the condition of the surface!  That is REALLY big news.  This IS application.  Although it still IS quite boring to most people!  Are you dumbfounded and surprised that I just said that?  Well the simple truth is that it is.  And to further prove it what do you think you will get if you were to show people the illustrations depicted here?  

Image result for point indent fracture

Now to turn this around we need to first look at the conditions in the field.  From the field to the lab so to speak.  I remember one case where I was shown a foggy appearance at the bottom edge of the outside of several windows on a house.  It could not be wiped off but was permanent.  The woman also said that all of the windows would fog up in the early morning.  This could be wiped off.  It was condensation.  This woman obviously had too much time on her hands.  All she did all day was look out the windows.  But nonetheless I still had to figure it out because I was being paid to do that.  The key to figuring it out was that the windows were "acid washed" with hydrofluoric acid.  To prove that the acid caused the effect I needed to make application "in the lab".  Of course I didn't have a lab.  But I did have a kitchen loaded with about 2500 chemicals and abrasives.  Also I could buy a brand new sheet of glass and expose it to HF in different ways.  In short I had to find out if I could duplicate the conditions I found in the field, but in the "lab".  Which I could and did do.  This was the first time that I learned how HF will change the surface of glass in such a way as to make it very hydrophylic, and actually attract condensation.  It happens almost instantly.  This is why some window cleaners using water fed poles will first apply a product based on a glass etchant, then apply a pure water rinse immediately after.  It makes the glass hydrophylic so that the rinse water drains off much better without leaving any spots.  It was also the first time I was able to duplicate a stage one and two static etch.  In other words a "vapor etch" where the acid rises as a vapor reacting with the glass and leaving the reaction byproducts on the surface as a white haze.  So you guys who have have been talking about how HF reacts with the tin side of glass, should at least consider that your individual case study might not be the result of this phenom. But didn't I say at the beginning of this paragraph that we were going to turns things around?  What I meant was when we learn how to do things as we have just discussed we should then show them to our potential customer.  I mean quite bluntly we need to stick them in their face.  That means we must etch a plate of glass right in front of them.  We need to show them how we can "scratch proof" a mirror.  We need to show them how the wrong solvents will break a piece of plexi in two in only thirty seconds.  These kind of demos are great for contractors who care about this stuff.  And when you do these things, watch their face.  When you see the smile you will have accomplished your purpose.  This works even when you are just cleaning glass.  Never leave a potential customer without cleaning their most dirty window in and out. Then watch for the reaction.  If they like what they see, you stand a much better chance of getting the job.  

Friends I don't have an atomic force microscope, or a scanning electron microscope.  I don't even have a high power light microscope.  I am definitely NOT a chemist.  Just one very crazy but curious old window cleaner who has learned to look at problems in a different way.  Knowledge of the devices used for testing and monitoring relative humidity, or determining the coefficient of friction are fantastic.  They have given us a great deal of insight.  I will forever applaud the IWCA Glass Committee for their research with Penn State.  But we need to make application of this knowledge in the field for it to change our businesses and change our lives.  To do this we absolutely must demonstrate what we know.  And by doing this, only then will we have learned a dynamic new way to market our business.  Come go with me friends.

WindOCoat Protection against Scratches

Imagine a product that can be applied to windows BEFORE the construction begins.  The glass is first cleaned, then the liquid product is brushed, rolled, or sprayed on.  In a short time it dries to a film.  Now concrete, silicone caulk, stucco, paint, stain, etc. can get on the window.  When it comes time to clean the window all you simply do is peal off the film in one sheet taking with it all construction debris.  The window is now totally clean.  No need to reclean it because it is clean.  Well this product already exists.  And it is called WindOCoat.

Your Code for Beta Testing is GlassSmart618

I have worked out a deal with Nanovations USA to provide a free sample of their product NG1010 for all of my Glass Smart Beta Testers.  You must use the beta testing code which is GlassSmart618 when calling in.  The sample is free but you will have to pay for shipping.

Nanovations glass coating technology is based on colloidal sol gel materials, were special formulated solutions self-assemble into a monolayer surface structure. The use of wet chemical technology makes it possible to use simple low tech, application methods  like spray and wipe , spray atomizing  or dip coating.
After the curing, which is the evaporation of the carrier liquid, the material bonds to the surface and the coating will self-assemble into the formulated and ultra-thin coating layer. The final coating layer thickness is in the Nano scale, and completely invisible. Functions can be added. Within the limitation of the overall thickness, it is also possible to add scratch resistance and dust reducing properties.
This structure gives the glass an extremely durable hydrophobic effect.

The completely invisible treatment cannot be removed by water, cleaning agent or with high pressure equipment. It is an extremely thin coating requiring the very least consumption rate. Coverage rates of 400 square meter per liter (14,000 square foot per gallon) are possible. NG 1010 for example, is the most cost effective and fastest to apply glass coating solution available.

NG 1010 was applied on the first high rise building in the world where such advanced technology has been used to treat the glass of the complete building.
On this landmark building, right on Sydney harbour,  more than 6000 square meter (54,000 square foot) of glass has been fully restored and protected.

I will be writing more posts about this product.  It is one of my Flagship products.  It can be used on buildings, vehicles, shower glass doors and enclosures, mirrors, and more.  The surface must first be cleaned of all contaminants such that it actually sheets water.  Then once NG1010 is applied it becomes highly hydrophobic.  It is very effective at resisting stains and scratches.  My suggestion is to charge at least four dollars per square foot for application.

Selling the ECloth to your Customers

Micro-Fiber Cloths are made from a blend of 100% polyester or polyester and polyamide (nylon).  The highest quality products are woven.  The very highest quality fabrics used for cleaning have a split fiber as depicted here.  It is split during manufacturing resulting in multi-stranded fibers. The split fibers actually grab the dirt and absorb liquids. There is no lint left behind like what happens with paper towels.  Again the split fiber is critical to the efficacy of the product.  Those micro-fiber products that do not have split fibers might be very inexpensive but they will not be anywhere near as effective. 

Most manufacturers will not mention that their product uses a split fiber.  To know whether it is or not just run it across the bottom of your hand.  If it is a high quality product it will catch your skin.  Another way is to wet a surface with a little puddle of water and try to push it with the cloth.  If it is micro-fiber the water will be absorbed.  If not you will simply move the water.

How the E-Cloth Works This is a video link

This is another video      

The ECloth Micro-Fiber is a high quality product with a dual polymer split fiber for cleaning glass.  It uses both polyester and polyamide.  Imagine micro-fiber on steroids.  Very smooth so as to maintain total flatness. This is necessary for glass.  Not so much other surfaces.  The glass cleaning cloth is a killer for mirrors and car glass.  I think it even sucks up water better than cotton towels.  Also for inside WFP work it should be a wonder product.  But you will want to buy one to try it out.  Just click on the link here in this post.  The company has an entire range of different products that can be used on other surfaces. You can purchase the glass cleaning cloths in bulk at a reduced cost and actually make a profit off your advertising.  Just load them in ziplock bags.  Then put your business contact info on the outside.  The contact link is  ECloth for Glass Cleaning Always remember your customers have customers.  And your customers will talk.  This is a great product for storefront accounts.  They will be able to use it to touch up their front doors, cooler doors, display cases, glass countertops, mirrors, and anything else made of glass.  The ziplock bag will be your business card that will be on display to everyone that uses the ECloth.  Whether it be a commercial account or a residential customer.  As for the product you should resell it since it will actually save your customers money.  They won't have to buy any more window cleaner.  It is totally green.  And will help to keep the glass perfectly streak free in between your visits.

Scratch Protection;...Breaking News!

There are so many myths surrounding this subject.  It seams like every sealant/glass coating manufacturer claims their product resists scratches.  Well guys;....I have just done it with Dawn!  So maybe they are right.  Time will tell.  It is an easy test.  I will tell you the story.

All you need to do for the test is take a simple plate of glass vertical or horizontal.  It doesn't matter.  Then polish it with a three to five micron compound.  I used my product SKRUB.  My Betas are quite familiar with this product.  I use a two by two foot mirror that I set flat.  Then I use a random oscillating sander with a felt pad.  Here let me show you a video.

This procedure shows how to convert hydrophobic glass to hydrophylic.  That was its intent.  But it also shows how easy it is to convert a glass surface to one that is VERY prone to scratches.  Since my affiliation with the IWCA Glass Committee I learned that all scratches begin with a PIF.  That is a Point Indent Fracture.  Also that rough glass is much more prone to scratches than smooth.  And that glass which is exposed to high heat/humid conditions, is also much more likely to scratch.  The simple solution is to just coat the glass.  Even if it is with only a one molecule thick film.  But the right one. Chemistry IS important.  The IWCA has also shown this with help from the Penn State Materials Lab.  And one that will last.  I mean just Dawn will work.  Spray a soapy solution in a small circle and buff it in with a paper towel.  That is all you have to do.  But when you soap it hard with an applicator, and squeegee off all the residue, you go right back to a surface that is prone to scratches.  It really is quite fascinating.  If you use a compound with the machine such that the glass sheets water perfectly as shown in the video here, then lightly run a dry fingertip across the surface, you can easily feel the roughness.  It looks crystal clear.  And it is.  But it is really rough.  All that is needed is a spot of soapy water.  I also applied a nano-coat product from another country that creates a hydrophobic surface.  It works really well.  And is supposed to last for two years.  Much longer than any other hydrophobic treatment that I have yet heard of.  This also works very good at protecting against scratches.  If applied correctly of course.  To test these surfaces for scratches I used the point of a small three by three inch glass square.  Glass scratches glass much easier than rocks, or metal.  Do you want to know what this product is so you can use it in your own business?  Than become a Beta Tester!  Just send me by email your full name, business name, email address, shipping address, and phone number.  I only ask that you write all about the results on Social Media.

There are benefits to being a Beta Tester you know.  You get the inside edge on many flagship products that no one else even knows about.  This gives your company the competitive edge over your local competition.  You also will have the opportunity for extra streams of income.

Exciting Future Projects for Glass Smart Betas

Super Soaps;  The first project underway right now is to find a super soap to replace most other commercial products out there.  We want a SS that will be the most concentrated cleaner available.  No need to buy water.  It also should clean very well.  Have just enough suds so we can see what we are doing for zero detail work.  When overlapping it should not leave a visible film in the direct sun.  Such a SS would also double for Trad work and as a feed soap for WFP work.  For WFP work it should first completely sheet a hydrophobic sealant such as Rain-X, Aquapel, or Enduro Sheild.  Second it should leave the least film when drained from such a surface. 

Synthetic Wool; Not steel or bronze wool but wool pads made from polymers such as nylon or another plastic.  The individual fibers or threads of the pad would be coated with or loaded with superabrasive particles.  Such particles would do the job of deep cleaning the pores of glass thereby effectively removing greasy fingerprints and other microscopic hydrocarbon residue.  The wool will not rust out or break up into pieces.  I can even see the use of much larger compositional abrasives that would be much softer than glass but still hard enough to chew off cured silicone caulk and other similar deposits.  The real advantage of using this type of product is it can be used with some of the more advanced liquid solvents.  Which brings me to the next line of products.

Green Solvents; I am not talking about the old high VOC carcinogenic solvents.  But new solvents that are much more environmental and better for your health.  But still are powerful enough to even soften fully cured silicone caulk.  These are currently NOT available to the window cleaning industry through our distributors.  But they are out there.

Superabrasive Loaded Bristle Brushes for WFP work;  These would not scratch defective glass surfaces as steel and bronze wool can do.  But would definitely "deep clean" glass that has been coated with heavy pollution such as what happens in cities like NYC.

Phobic to Phylic Conversion Wands for WFP work.  These would more effectively remove the hydrocarbon pollution that is responsible for hydrophobic glass, and do it at the same time the windows are being cleaned. 

Slow Release Stain Removal Pads;  Such pads are great for removing stains from windows by just using water.  They will be circular and go on the bottom of any rotary system.  Such as a polisher or grinder.

A Hydrophylic Sealant to create and Antifog Effect;  Mostly for mirrors in bathrooms.  But such would also be great for WFP work.

Another very big surprise for the Glass Smart Betas will be the chance to work along with me on the Glass Smart FLAGSHIP Products!  These will be featured in the left hand column of the blog.  We will have the chance to learn about these before anyone else.  Which will give all the Betas a definite advantage over their local competition.

Super Soaps make Water Wetter for Cleaner Windows

How wet is your water?  The wetter the better.  Because wetter water cleans better.  So how do we test for wetness?  Try coating a small window with a hydrophobic sealant such as Rain-X.  Make sure it beads water very well.  Next mix your Super Soap (SS) in two gallons of pure water at a ratio of one teaspoon of SS to two gallons of water.  (It can be mixed at a concentration of .1% or less.)  Then wet the hydrophobic surface with the SS solution/cleaner.  I like to put the solution in a small one gallon garden sprayer.  Then I remove the nozzle.  Maybe even just cut the nozzle right off so you just have a hose.  Make sure the water comes out as close to a laminar flow as possible. Then wet the surface from the top to the bottom so that it completely sheets over the entire surface.  You will find that other window cleaning soaps at the same exact ratio will not sheet over the Rain-X surface as efficiently.  They will break up.  The reason for the laminar flow is to keep the suds down as much as possible.  No suds at all would be perfect.  I have included a video here so you understand what I mean by laminar flow.  But even more than that this guy demonstrates exactly how you can build your own for WFP work.  We need to be talking to all of the manufacturers of WFP equipment to see if they are planning to use this technology in their products.

This test will show the superiority of super wetters.  Which is why they clean so well.  But also at a very diminished concentration.  This test is also great for showing how effective super wetters can be in WFP work.  Once the water has sheeted over just let it drain down completely.  This could take about fifteen minutes.  The best ambient conditions to work at are an air temperature of fifty degrees, and high humidity or just overcast.  Again don't allow any suds.  It should drain off laterally with a rather even line of separation between the dry area at the top and the wet area at the bottom.  There will be some "fingers" that will form as the solution drains.  These will grow as the solution moves towards the bottom.  They will show colors too.  But the results should be perfect.  Make sure you do not test on a hot sunny day such that the solution dries too quickly.  It cannot evaporate before it drains.  These are two separate effects.  To use a SS in WFP work I am guessing a feed line would work best.  You might want to mix up a concentrated solution first.  Then feed this directly into the wash/rinse line.  You should be able to turn the feed on and off as needed.

Next for trad work using a squeegee just mix up a bucket at a .1 or .05 % concentration.  .1 is one to 1,000.  Also .05 is one to 2,000.  There is 768 teaspoons to a gallon.  So a single teaspoon to a gallon would be slightly more concentrated than .1%.  I am guessing one and a half teaspoons to two gallons would be closer to .1%.  Or you could try one teaspoon to two gallons of water.  What we are trying to accomplish is to find the lowest concentration to use in our buckets.  I say two gallons because that is what I carry around.  When I mix in my Dawn I use a much greater concentration.  We are also looking for a SS that will clean well but leave the very least film.  I have discovered that there are certain windows which will show a film much quicker than others.  These usually have a good sun exposure.  And there is something different about the surface of the glass.  Whether they are clear or dark tinted. 

To do this test I would first completely rinse your applicator and bucket.  Just so there is no contamination from any other soaps or chemicals.

The Destructive Power of Hard Water Spots

Hard Water Spots begin invisibly.  You just simply cannot see them.  However you can bring them into view when you fog the clean glass with your breath.  Fogging the glass will also tell you if you have completely removed all of the mineral deposits by polishing with a superabrasive.  The fog will not reveal anything.

Now as time passes the spots will become heavier.  Then they will become visible in the direct sunlight.  As more time passes they will become much easier to see.  Even on cloudy days.  Then they will become heavier and heavier until they are like braille.  If they were removed when they first showed up, and the glass was sealed with a quality sealant, the windows could be effectively maintained at a reasonable cost.  But if allowed to get really thick extreme measures will be needed to "restore" the windows to original clarity.


Each new spot usually forms directly on top of the previous spot.  This is because dry spots catch water drops.  Which drops will dry in the sunlight.  As water drops dry/evaporate the minerals become more concentrated.  All drops dry from the middle out.  Such that the outer edge becomes loaded with mineral deposits.  The outermost region of each spot has the most minerals.  This is also the part of the drop that attains the highest pH just before all of the water evaporates. It is the area where a dynamic stage two etch is most likely to happen.  Owing to the very high pH.  This can actually be seen sometimes as a clear distortion of the glass when it has been polished.  The clear distortions will take on the exact shape of each spot.  This is not theory.  I have proven it on a piece of dark glass.  Dark tinted glass is more easily etched by hard water.  It is also the most difficult to restore.  Transparent glass is easier to clear.  Then low e windows that have been coated on the first surface/weather surface are the easiest to restore.  Low e coatings can be damaged also by hard water spots.  These coatings are very thin.  So the mineral deposits can literally eat right through them.

The bottom line here is to only hire a window cleaning company that is Glass Smart.  They must be spot wise.  Hard water spots can come from the garden hose, sprinkler systems, concrete, brickwork, exterior stucco, and more.  Once they begin your window cleaner should recognize them.  They should be immediately removed and the glass sealed.  Then the windows should be cleaned again in six months.  The sealant should be checked and any new spots should be removed.  At this point it will be much easier to remove new spots and rejuvenate the sealant.

Hard Water Spots can be quite destructive.  If allowed to build up to a thick scale the cost to renew or restore the glass to the original clarity can cost as much as one quarter the cost of replacement.  Not to mention the cost of restoring any anodized aluminum frames.
