Headlight polishing

Did you know the acrylic headlight lenses on the Camry can be cleaned and polished? Some discoloration, darkening, or clouding seems normal with age. Found some white polishing compound designed to clean the surface of automotive paint. Instructions say, apply with damp cloth (used cotton diaper) and increase pressure as material is absorbed into the cloth. Headlights come out bright, shiny and new looking. Very nice. Finished with Plexus plastic polish, although the container recommends using automotive wax, which should also be fine.
