Can tarnish remover be used on silver-plated and gold-plated jewelry?
It is better that you didn’t use it on those pieces. Tarnish remover can be too harsh for plated items. It was designed for sterling silver, gold, copper or brass jewelry. It works in just a few seconds (2-10) and will remove stubborn oxidation and tarnish. Do not use this product on articles containing porous stones, pearls, painted jewelry, aluminum, stainless steel or lacquered surfaces. Do not immerse jewelry items in the tarnish remover, dip them.
