Window tint film is a thin sheet of Mylar plastic. Mylar easily scratches and will be destroyed by ammonia. To clean tinted windows, use mild cleaners and water only. Tint film that has been scratched can be polished with cleaners designed for the vinyl windows often found on convertible tops. The product I recommend for polishing and regular maintenance of window tint film is Plexus.
Plexus comes in spray and is safe for use on plastic, plexiglass, and window tint film.
In addition to polishing your window tint film, Plexus works great on your tail light and headlight covers. Windshield Wipers Windshield wipers are necessary to clean your windshield and rear window when it rains, snows, becomes bug ridden, or dirty from long road trips. Wipers perform best when the rubber is in good shape and the glass is fairly clean. You should make it a habit to clean your front and rear wiper blades at the same time you clean your glass. After cleaning your glass, use a damp cloth to wipe the rubber blades, removing bug residue, wax, and other dirt build-up.
