Car light covers, or lenses, are made of molded polycarbonate plastic. Polycarbonate is a better material than glass for car light covers, as polycarbonate can withstand flying road debris that would chip and crack glass lenses. A downside to polycarbonate lenses is that, being plastic, they are susceptible to the damaging effects of the sun's ultraviolet rays. This damage shows up as cloudy or foggy light covers. Replacement car light lenses can be expensive, but you can clean your lenses and restore their clarity at a fraction of the cost.
Clean the car light covers with a flannel cloth and a commercial car wash solution. Rinse them well, making sure to remove all sand and grit. Wash and rinse them again, as any sand or grit remaining will cause more damage to the lenses during the cleaning process.

Run a second line of blue painter's tape next to the first line to provide extra protection for the car surface. Remove the trim before masking the area, if the trim around your car light covers is easily removable.
Wash the car light cover with car wash solution to remove any polishing compound residue. Rinse the light cover well, and dry with a flannel cloth.
