Soft, effective Sunshine® Cloth, with its special micro-abrasive, cleans jewelry brilliantly! This cloth safely cleans, removes tarnish and polishes gold, gold-filled, and silver, leaving a deep, long-lasting luster. One cloth will last months to a year. To use: Rub polishing cloth against jewelry until it shines! The cloth will darken as the compound is removed but you can use the cloth until it is almost completely black. Do not wash or get the cloth wet.
