This redecker copper cloth cleans pots, pans, sinks, ovens, ceramic cooktops, glass, stainless steel, etc. Fine copper threads loosen even the most stubborn dirt carefully because copper is a soft metal that is non-abrasive. When used in wet condition, it will leave no scratches on enamel and ceramic cooktops and will give your sink a high sheen! Use in wet condition only! Double-layered for extra strength, extreme long lasting, washable in the washing machine at 60°c/140°f (please put in a line-sack or sock).
