PolySkrub (PS) is a micronized plastic powder based on a particle that is soft enough to not scratch glass but hard and sharp enough to dig through fingerprints, cured silicone caulk, paint, urethane, waxy substances, siloxane based concrete sealants, and more. The most common and simple way to use it is for very dirty windows that need to be scrubbed. First soap and squeegee the window. Then soap it again with clean soapy water. Next sprinkle PolySkrub (PS) on a damp clean applicator. You can use a medium sized salt shaker. Next skrub the window with that applicator. Lastly squeegee again. This is the best way to get the most out of the product. With very little waste. And you won't leave many little plastic particles behind to get under the squeegee rubber. Which will only cause very fine stray water lines.
The ultimate goal here is to find ways to get away from using a metal razor every time you clean windows on jobs the first time through. This simple practice could save you a tremendous amount of grief if you were to scratch even just a single window.
If however you are attempting to remove cured silicone caulk, paint, or something else;...you will likely need a different technique. The idea here might be to use a soft damp sponge sprinkled with PolySkrub (PS) directly on the paint or other material. You might need the concentrated pressure to eat through the paint. Another idea would be to coat the paint or silicone with an organic solvent. Then scrub it with PS. This is a better technique rather than mixing the solvent along with PolySkrub (PS) because the solvent could easily soften the PS so that it becomes less effective at chewing through paint, silicone, etc. Solvents typically take upwards of a half hour to soften paint. Which might be too much time to expose the PS to.
There are many techniques that you will develop as you move ahead in using different solvents (or just soapy water) along with PS. I will be working with members of NEGSA here in New England to develop these different techniques. Which will be explained and demonstrated by video here on the Glass Smart Blog.
