BPA is just one result from incorrect care of polycarbonate products. Degradation can also cause loss of clarity and even compromised physical properties in finished goods. The simple answer is to make sure your customer knows how to properly clean PC products. Avoid most common solvents, including methyl alcohol. Warm water is fine (below 60C) as are vinegar solutions, common household alcohols like ethanol and isopropyl alcohol (rubbing alcohol). Even dilute hydrochloric acid is okay, and borax is a good cleaning agent in water. Common household cleaners to be avoided include ammonia, strong alkalis like drain cleaners and lye, as well as nail polish remover (acetone).
