McKee's 37 Clear Plastic Cleaner & Restorer is a two-in-one cleaner and restorer for clear vinyl windows, the type found on convertible tops, Jeeps, boats, and more. Clear vinyl windows naturally yellow and discolor over time due to damage inflicted by UV rays and airborne pollutants. McKee's 37 Clear Plastic Cleaner & Restorer contains ultra-refined abrasives and cleaners that restore the clarity without dulling or hazing the window. What you're left with is a perfectly clear window that looks as good, if not better than, the day it was new. This product works equally well on clear plastic surfaces found and around your vehicle, including the instrument cluster.
