Whether maintaining polished aluminum valve covers, alloy wheels, stainless steel trim, nautical hardware, or brass, you'll appreciate how easily this paste removes tarnish, light oxidation, and scratches without much pressure. Just a small amount on a soft cloth goes a long way. Leaves a protective film to help prevent future tarnish. Also works on plastic lenses, fiberglass gel coats, and some paint. Not recommended for items plated with silver or gold.
