Scratch Maintenance Seminar/PPP Meet #2

 The first NEGSA Meet at the Poor Peoples Pub in Sanbornville NH focused on methods for testing abrasive and acid based products for safety.  The second Meet will focus on the service of Scratch Maintenance.  This Meet will also include seven hands on demonstrations.  Scratch Maintenance is NOT being offered by any window cleaning company that I know of.  And should be a very profitable service.  It should also help you acquire many regular commercial jobs.  Some of the demonstrations that will be shown at the PPP Meet you will be able to show to your potential customers.  They will be very powerful marketing tools!

  When glass is smooth with no factory surface defects and is not frictive, it is not prone to scratches.  Therefore the first step when the Glass Smart window cleaner acquires a job is to clean all the windows very carefully and inspect each one for scratches. Whether the building is brand new or not.  Then make notation of the results.  Including notes on which surfaces are defective and or frictive.  

Defective surfaces come that way from the factory.  And frictive surfaces can also come from the factory too.  But not only!  There are certain acids and abrasives that can change a scratch resistant surface to a frictive surface.  There are also chemistries that can change it back, and even make it more scratch resistant.  It is going to completely shock all attendees as to exactly which ones these are.  And again I will be demonstrating this.

Since the Glass Smart professional window cleaner will not be the only one to clean the windows, they should be cleaned and inspected on a very regular basis.   If any chemical treatments have been applied they should be inspected for integrity.  

There are also completely transparent plastic films that can be applied to certain areas such as door handles. or the bottom of doors where people push it open with their feet.  Also places where foodstuff accumulates that must be removed on a regular basis.  Such as the bottom part of restaurant windows.  Here is a sample of one of these products.  Very easy to apply.  You should charge by the square foot and use your name.

Demonstrations;

How HF creates a frictive surface which will make the glass scratch sensitive.

How optical silica compounds or cerium oxide also creates a frictive surface making glass scratch sensitive.  Every time!

Which hand applied coatings can change glass back again to a scratch resistant surface.

What chemical treatment will not only resist scratches but will also resist hard water deposits and will last the longest. 

Testing HCL on glass for reactivity using the scratch method.

Demonstrating the penny method to test for defective surfaces.

Window Cleaning/Consulting Fusion

 Building owners and maintenance management companies should ONLY hire window cleaning companies that are capable of accurate inspections of windows.  The goal is to prevent the loss of many thousands of dollars from "sick windows".  

Hard water spots; HWS can form on any fenestration surface whether that be glass, metal, or plastic.  The technique used to remove such is very much the same except it is quite difficult to get them off dark tinted glass.  A window cleaner who is Glass Smart will know when the integrity of the surface has been compromised.  Before this problem becomes too difficult to repair.

Scratches: Such can be very mild or rather large.  They can be dramatically enhanced by the wrong chemicals.  We need to know exactly what they are.  What products they are used in.  And especially how to identify where they cam from if we happen to reveal them during the window cleaning process.

Negative deflection; This is an extreme problem where windows can spontaneously implode with a very loud bang under the right conditions. This does not matter how old they are.  There is a very simple test that can detect this problem.

IG Unit Seal Failure;  Definitely not an attractive problem.  It begins very slow but can quickly become a huge cloud in the middle of the window.  When it first begins it is virtually impossible to see but can still be discovered.  There is nothing that can fix this problem.  It is good to know when you are buying a house or else you will have to keep it.

There are many other problems that can develop.  The Glass Smart window cleaner will know what they are and keep a very close watch on your building.  Every time the windows are cleaned.

The First NEGSA Meeting 9/30/21


Today we had a VERY productive Meet at the Poor Peoples Pub!  We learned how to use a very dilute solution of HF to test our commercial and home made glass restoration products.  We also learned about the three different destructive effects of HF commercial products used for restoration.  Everything was demonstrated right on the table.  These were things no one had seen before so we now all share the skills.
This is just the beginning!  Moving into the winter now I will be meeting once a month.  And will be focusing on technology that will help us to develop Glass Smart companies that will set us apart from other cleaning companies.  The bottom line is that no one can afford to hire a window cleaning company that is NOT Glass Smart.
The next NEGSA Meet at the PPP will focus on the theme of "Scratch Maintenance".  We are also starting an educational newsletter for EVERYONE of our customers!
I am here for you.  Come and join NEGSA.  Receive your logo.  Receive your eletter through email, and distribute it to all of your customers.  And most important come to our monthly Meets.

NEGSA NH Meet Will Discuss Etched Glass

The NH Meet will be held at the Poor Peoples Pub in Sanbornville, NH on September 30th a Thursday between 3 to 5.  Here are a few pictures of the PPP.

















I will be demonstrating the three different destructive effects of hydrofluoric acid.  The first will be the clouding effect.  This usually happens on contact.  But can also take time from vapors.  The second is the distortion effect which is typified by total dissolution of the glass surface.  I have seen it manifest as long lines from concrete sealant run off and what I call an orange peal effect from hard water spots.  The third is the mag effect where any scratch or patch of scratches are magnified by 50 times over.  This happens instantly.  Any light scratching is magnified every single time so they become very visible!  

I will also be demonstrating how to use the last effect to test a simple compound for scratching.  If there is any chance at all that a compound will create scratches it is possible to text it on a mirror plate using both your product in question and a product based on as little as two percent HF.

When performing stain removal with a compound there are three factors that must be addressed.  The quality and properties of the window surface, the quality of the polishing compound, and the restoration technique employed.

It is a protection if we are familiar with these different visual destructive effects.  Simply because they could be lurking underneath dirt or any other contaminant like concrete sealant, paint, wood stain, thick pollution, concrete, or something else.  When we clean using routine or nonroutine methods we could very easily reveal etching, scratches, or both.  Then we could be sued by the home owner.  They could very easily claim that the etching or scratches were never visible until after the windows were cleaned.  And blame the window cleaner.  This make me want to have a waiver signed for every new job

Frictive (grabby) Glass

Let me tell you a story.  Just recently one of the founding members of NEGSA and myself were cleaning the windows at a prefab log cabin.  Real pretty little place.  Here is a picture of Johnny working on the outside.  The house was going relatively well.  The insides were great.  So were the outs until he got around to this side.  



The glass became what he calls "grabby".  I call it frictive.  It has a tendency to grab the fabric of your wand.  This particular surface was also stained from either a cleaner that was wiped by hand with a rag and hard water spots that were left probably from a garden hose.  Very unfortunate because the only way to remove the stains was to polish it with a machine.  The glass cleaned up rather well with some 0000 steel wool.  No scratch but it was absolutely impossible to scrape with a blade.  That would have caused scratches!  The razor dragged real bad.  

What was very interesting was we tested a commercial polish which I have proven works very well on windows without scratching.  It removes hard water spots even with 0000 steel wool from low e factory coatings.  No scratches at all.  Leaves a bright finish in the direct sun.  But.  When used on our log cabin it became plain very fast that it would leave scratches and turn the window white with a haze.  This shows that window surfaces are all different.  The products are the same.  But the surfaces are different.  Another member of NEGSA said to me once, yes it is true, glass is absolutely NOT all the same.  We were talking about scratch sensitive glass. 

This glass could be restored and sealed with a very high quality polish.  Likely a white cerium oxide and a polishing machine.  I would try a low rpm with a soft wool pad or a foam pad.  You would want to get a waiver signed to make sure you are free from any liability to experiment.  Which you would need to do to figure out exactly what procedure you would need to use to clear the stains.  Then I would suggest sealing with Nanovations NG1010.  The price should start at four bux per square foot.  But it could easily end up at a hundred USD per plate.  When you explain all of this to the home owner they usually refuse.  

The bottom line here is that nobody seams to know how easily glass surfaces can be damaged.  So we need to keep on working at educating the masses.  I am thinking about looking around at different gatherings of various professionals like real estate brokers and agents.  Or home builders.  And asking for an opportunity to give a twenty minute talk.  I will be setting up talks like this within New England for the members of NEGSA.  And will be writing about these right here.

A Waiver for Every Window Cleaning Job!

Every job has the potential for damage.  New glass that has never been cleaned sometimes has the greatest potential.  For many different reasons.  It could have a defective (scratch sensitive) surface right from the float glass manufacturer.  Which has been covered with construction debris.  Even stickers from the window manufacturer. Razor blades cannot be used on this type of defective surface without causing scratches.  New glass might be scratched already.  Defective or not.  This can happen at the window manufacturing plant, or on route to the construction site.  Glass passes through many hands on the way to the construction site.  And it is impossible to know who might have cleaned it or how it has been stored before installation.  All of this means that the professional window cleaner must be Glass Smart.  They must be able to identify by inspection any preexisting scratches, abrasions, etching, or other surface damage 'before' cleaning. 

Problems with new glass are only the very beginning.  Windows that are months, years, or decades old are potential nightmares.  Anything that you imagine could be lurking beneath the dirt or stains.  I call this the glass history.  Lets say a building is completed.  The windows have been in storage for six months.  During this time they could have easily sustained damage by scratching or etching.  But the cleaner that was used didn't identify the damage.  So the building was signed off and the windows got dirty again.  It was sold and now another cleaner was called in.  The damage couldn't be seen until the windows were cleaned again.  This time the damage was visible to everyone and the second window cleaner was blamed.  That company was sued for scratches that were caused by someone else.  Nothing was ever done to fix the problem however and the building was sold again to someone else.  Who had no idea of the problem.  The windows were cleaned again by a third window cleaner.  But they used a "professional glass restoration" product to remove the excessive dirt and runoff from a concrete hydrophobic sealant.  Or maybe hard water stains.  The windows cleaned up very well.  But the product was based on a glass etchant such as hydrofluoric acid.  This type of product magnifies scratches by 2,000 times every time!  At this point the latest owner is very angry.  He never seen those scratches before!  The window cleaner might claim that he never even used a razor blade.  Nothing abrasive at all.  And has no idea where the scratches came from.  The latest owner of the building doesn't care and files a lawsuit.  Usually this is the time that I am called in to make some sense of the situation and point the finger in the right direction.  There are usually two lawyers.  One representing the window cleaner.  Another representing the building owner.  Of course no insurance company will want to pay for anything.  This isn't a car accident.  Not that easy.  So I am usually called on for some quick easy answers.  And maybe to serve as an expert witness over the phone.

I could go on with stories involving many different situations.  Involving plastic glazing, solar film, low e mirrored glass, anti-reflective coatings for photovoltaic panels, or low maintenance (self cleaning) coatings.  The list goes on.  But the singular point that I am intending to make here is that the window cleaning industry is changing radically.  Windows are not what they used to be.  The potential for surface damage and lawsuits is very real these days.  Every window cleaning company must be aware of this.  And work very hard at becoming Glass Smart.  It also would not necessarily be a bad idea to adopt a First Time Waiver (FTW) for every new account.  There should be a waiver to do the first window for testing and approval.  A second to get paid for half the job and get approval to finish.  And a third to get signed off which will assure getting paid for the rest of the job.  So essentially a waiver for every job!  This is one of the very best methods for protecting your company from lawsuits.  Because they are right now destroying so many innocent window cleaners.  As a consultant I have been called into many situations such as the ones I have described here.  These were totally needless!
