How to Clean Lexan Windshields

Lexan is a lightweight, scratch resistant plastic-like material that is used to make windshields and car racing and motorcycle eye googles and face masks. Over time, Lexan windshields can become dirty and scratched. Clean them as needed. Never use chemicals or cleaning agents to clean Lexan as this can weaken and discolor the windshield.
