When Glass Damage Is Real. Polish It Out.

CarPro CeriGlass is a cerium oxide glass polishing system that removes etched water spots, road film and fine to medium wiper scratches — supplied with a hand applicator and towel.

No cleaner fixes etched glass. Damage has to be polished out. Once hard water has bitten into the surface, or grit under a wiper blade has scored it, you're looking at a correction job — and that's a different tool entirely. CeriGlass blends ceramics including cerium oxide with nano components and mild abrasives, which is why it handles acid rain spotting, mineral etching, road film, bird strike stains and wiper scratching without the distortion older cerium oxide powders were notorious for. Work it with a rotary for swirls, light scratches and sometimes tiny pits; a DA handles water spotting and shallow marks; and the included hand block deals with milder spotting on smaller areas.

Reference Points

CeriGlass will stain black trim and should be kept off paint — mask surrounding surfaces, or wash the vehicle immediately after if contact occurs. It is not suitable for exterior tint film, painted or coated glass. Always test on a small inconspicuous area first to confirm it doesn't mar the surface, and refer to the manufacturer's label for current guidance.
