Just thinking. I was cleaning one of my storefronts the other day that sees a lot of road dust. And was thinking what if I were to coat the glass with a hydrophobe that would make them real slippery? Then I should be able to run a microfiber cloth on a doodlebug. Only a very fine mist of pure water should allow me to remove the dust in about ten seconds. I could cut my time by about 75%. Has anyone ever thought about doing something like this?
