Regular cleaning and shielding when not in use will greatly enhance expected life. The use of harsh chemicals for cleaning should be avoided, as these can scratch the material. Clear PVC should only be cleaned with a diluted solution of mild soap and warm water. Rinse with clean water and dry with a soft cloth or a sponge. Do not use solvents or chemical cleaners. Do not expose UltraClear to abrasion. The surface can be scratched by rubbing with a coarse cloth, or even in general usage and these are impossible to remove.
