The Future of Stain Removal

The key to winning a 50,000 dollar stain removal contract lies in being able to guarantee the results for at least five years or more!  And the only way this can be done is to apply a glass sealant (after removing the stains) that is very resistant to alkali attack.  Then you must also have the means to very quickly remove any newly formed hard water spots as you routinely clean the windows. But without removing or damaging the sealant.  Even replenishing the sealant as you clean.  So that your routine cleaning becomes a three step stain removal, replenishing, and cleaning procedure.  All performed simultaneously.  This must be done as close to the original routine cleaning price as possible.  But the most important consideration is that you will have the everlasting solution to the problem.  This will help to ensure that you keep the contract.

The first step requires locating an alkali resistant sealant.  You can chose a hydrophobic or hydrophylic treatment.  The very nature of hydrophobic sealants presents a problem in that they create water drops.  Drops leave spots.  Which are concentrated mineral deposits.  As each new drop forms on top of old spots, the pH of the evaporating drop continues to increase with each rain or sprinkler cycle.  Ultimately as the spots age they can potentially eat into the sealant and lock onto the silicon dioxide surface.  Logically then the better choice would be a hydrophylic sealant.  Or at least one with a much lower contact angle such that rain will sheet off instead of forming tight drops.  It would be best too if such a hydrophylic coating/sealant were also very resistant to alkali attack.

Removing newly formed mineral deposits from such a surface without doing damage to that surface is possible using a compositional scrub.  That is abrasives that are soft enough to not remove the hydrophylic coating but aggresive enough to remove any mineral deposits which have formed on top of that coating.  I discovered very early on that it is possible to use four zero steel wool to remove newly formed aluminum screen burn on a Rain X surface without doing harm to this hydrophobic sealant.  In fact as you start to scrub your cleaning water will begin to bead as you break through the new stains. Revealing the hydrophobic polymer underneath those stains.  Which has not been damaged by time or your scrubbing technique.

It should be possible to periodically restore, treat, and clean by applying the fluid/chemical with a compositional scrub based applicator. Then wipe dry using a squeegee.  Periodically you can check the surface by hitting it with a small stream of pure water.  It should sheet off leaving very clean glass. Good for a Water Fed Pole maintenance. 

At the time of this writing most of this information is quite theoretical, experimental, and controversial.  But it seams to me to be the most logical course to take to solve stained window problems.  I am in discussion with various companies and chemists that specialize in this technology.  So we will see what the Future holds.  This is one for you Perry!

Polishing Glass;...RPM verses FPM

Speed, speed, speed!!!  600, 1500, 3000, 5000, or even 10000 RPMs?  How many RPMs do we need to use?  RPM stands for Revolutions Per Minute.  Did you know that the optics industry uses FPM? This stands for Feet Per Minute.  If you took a point on the outer edge of a rotating disk how many feet would it travel?  If your disk was six inches and it was spinning at 1000 RPMs, that point would be traveling at 1571 FPM.  What if your disk were 3 inches in diameter and also traveling at 1000 RPMs? Then a point at the outer edge would be traveling at 785 FPM.  Half as fast!  What if you were polishing glass with a half inch Dremel bob moving at 10000 RPMs?  That would be 2618 FPM.  This is ten times the RPMs of the six inch disk, but only 1047 FPM more.  I think you get my point.  FPM is a more accurate definition of the "speed" of a polishing disk.  This is also the reason why I have chosen to use a ring/pad to polish glass.  There is a much less variance of speed between the outer and inner edge of a pad that is only one inch or less wide.  In fact there is less of a variance the larger the pad/ring.  There is also less of a variance the thinner the ring.  So a one half inch wide ring would have less of a variance of the FPM of the outer edge and inner edge, then the variance of the outer and inner edge of a one inch wide ring.  This is important if the precise "speed" of the ring is critical to the performance of the polishing system. Most of the time it does.

Slow Release Pads

The first prototype has been created.  And has been demonstrated in the video shown here.  You can see the orange cerium oxide.  It has been loaded into a special polymeric matrix that breaks down slowly by simple soapy water.  So that when polishing hard water stains from windows this can be done quickly with no mess.  All you need to do is reapply soapy water when it starts to dry out.  To check your progress as you go just squeegee a dry area and check for clarity.  When done just soap and squeegee the entire window. There should be little to no overspray or rundown to clean up after.  This dramatically reduces the time it takes to "clear" a window. Further you will only use exactly the amount of cerium that you need.  This will reduce your cost.

The first SR pads that come out will be based on a high quality optical grade cerium oxide.  But this technology will allow me to develop other pads in the future that will offer additional benefits. Cerium is not the only superabrasive out there. Diamond superabrasives have been used in optics polishing for many years.  I have written about diamond restoration already in this blog.  Different superabrasives can also be blended for better performance.  Remember my post "The Particle Zoo"?Likewise it is possible to build SR pads based on softer compositional abrasives for quickly removing silicone caulk that has been shmeared all over every square inch of every window.

If you would like to get on as a Beta Tester to purchase any prototype products developed just send me an email.

Wobble Wheel Ergonomics

Ergonomics is the new buzz word these days.  Especially with Perrys Power and Control WFP handles as of recent.  Perry Taits Future of Cleaning is already a revolutionary company in so many ways.  Well I would like to introduce a new wordage.  That being gyroscopic precession.  GP is a wonderful and amazing property of anything that spins.  Including the Wobble Wheel Glass Polishing System.  Lets see why.

The gyroscopic precession of the Wobble Wheel is seriously increased by the six large holes evenly placed around the center universal joint.  It is also increased by moving the polishing material or lap out to the edge or rim of the wheel. In so doing the wheel takes on an antigravity effect.  So the wheel takes on a weightlessness.  When working with tools light is good!  Very ergonomic.

Another ergonomic feature involves the fact that the Wobble remains totally flat on the glass at all times.  It does not tend to grab the window forcing the operator to wrestle with the tool the whole time.  This dramatically reduces physical stress which is definitely ergonomic.  In the six inch Wobble Wheel video my friend demonstrates this effect by easily working the wheel at full speed with a single hand!

So if you are looking for a way to polish glass effortlessly;...the Wobble Wheel is the way to go.  I am currently working with a manufacturer to bring it to market in kit form.

Wobble Wheel Maximizes AntiGravity Effect

My six inch Wobble Wheel that I have developed for polishing flat glass surfaces has a gyroscopic nature.  This is simply because it is a wheel and it spins between 1200 and 2000 RPMs. Any wheel that spins has a gyroscopic effect.  Which means that any spinning wheel also has gyroscopic precession.  Which appears to be a kind of antigravity.  If you would like to see what I am talking about check out this video. https://www.youtube.com/watch?v=GeyDf4ooPdo  Just copy paste it into your browser if it doesn't click for you.  It is definitely way too cool!  Nonetheless this effect does make it easier to work with wheels that have less weight and greater gyroscopic precession.  To accomplish this it is necessary to transfer most of the weight to the outer edge.  Which I have done by designing the aluminum base with six large holes.  The polishing pad is also a simple ring.  Because of these two innovations most of the weight has been moved to the outer rim.  So the gyroscopic precession has been increased, including what appears to be also;...an 'antigravity effect'.

Does this interest you?  Would you like to own your own antigravity Wobble Wheel?  Just send me an email henrygroverjr@gmail.com
