Simplifying Stain Removal

Stain Removal can be a rather messy affair.  The best "one step" polishing compound or slurry is based on cerium oxide.  This is either a thick compound or a water slurry.  In either case it is very difficult to apply.  It is also very difficult to use without spraying compound all over the other windows, or the window frame.  Usually so much of it is used that when cleaning the window much of it will drip down onto the concrete or other sills or exterior facade.  This can discolor the exterior wall directly underneath each window.  

Another problem has to do with the expense of the compound.  Most people have chosen to use cerium oxide powder which has dramatically increased in cost over the last several years.  It becomes very expensive when it is over used.  You see in reality it doesn't take very much of this at all to clear most stains.  

Timing is another concern.  It takes a lot of time to keep on applying the compound/slurry to the glass as you are polishing.  Then if you use too much it can take a lot of time to clean up after.

With a slow release pad all of these problems are eliminated!  I can coat any pad that you are already using with a custom blended slow release plastic coating.  It goes on like a thick paint and then hardens to a solid coating.  Which coating can be loaded with any microcrystalline polishing powder.  So we can use an optical silica, zirconium dioxide, cerium oxide, aluminum oxide, silicon carbide, or even diamond.  Or we can precisely blend any of these powders.  

To use a slow release pad you first must clean the window.  Then just apply a clean soapy water and begin polishing.  After about thirty seconds the hard plastic coating will begin to dissolve in the water releasing just the right amount of microcrystalline powder.  Once done all you need to do is soap up the window and squeegee it off.  Wiping up the bottom edge.  There will be very little residue to wipe.  Since you are using only a very little amount of powder and only have to apply water,  There is very little mess if any.  Also the expense is dramatically minimized.  Further the time to clear the window is likewise reduced.  All of this greatly simplifies the job.  It likewise reduces the total expense.

There is even the option of adding acrylic or walnut powders to the coating for working on coated glass.  It is necessary to test whatever coating you are working on to determine whether or not a custom slow release pad will cause scratches.  This could be a very practical way to remove residue such as concrete sealer/water proofing from low e coated glass.  There are water miscible solvents available that will soften concrete sealers, silicone, paint, and wood stain.  These will also dissolve the plastic coating of a slow release pad thereby releasing the acrylic or walnut shell powder to physically rub off the paint or whatever else which has already been softened. Then all you have to do is agitate with soapy water and squeegee it off.

I am now working on a series of videos to demonstrate exactly how each of these custom pads work.  Again it should be emphasized that any polishing pad can be coated with a slow release plastic.  So if you have a felt pad that has a crack and peal backing to stick on a wheel we can coat this.  Or if you have a soft pad that has a velcro backing we can also coat the front of this.  There are many different applications.

Here is an old video I made several years ago using a special wheel I created and a hard felt ring/pad with a slow release cerium oxide coating.  The wheel wobbles because it has a universal joint built in between the shaft and the polishing wheel.  This keeps it flat on the glass all the time which makes the system very easy to work with!  But.  Any wheel, machine, or stain removal system can be used.  All that needs to be done is to coat the pad.
