After seeing the Fuller Brush advertizement about their product called Full Crystals that washes windows 20' away and cleans brick and stucco without scrubbing it, I ordered a $20 kit to see if it removes the grime from motorcycles that spray carwashes leave behind. However, I'm a little hesatant to try it on another one of my bikes. On my PC it cleaned the hell out of the engine and frame, but it melted away the body work.
