The OG silver (and all precious metals) polishing cloth. Sunshine cloths are impregnated with special micro-abrasives and a cleansing agent that removes tarnish and grime to leave a lustrous, long-lasting finish. The long-lasting cloth keeps effectively polishing until it is worn through. Cleans and polishes all types of wire and jewelry; gold, gold filled, sterling, brass, and copper. These are incredibly long lasting and will continue to work long after it has turned black from polishing.
