Copper makes sensitive objects shine! The copper sponges clean pots, pans, sinks, ovens, ceramic cooktops, glass, stainless steel, etc. especially thoroughly and gently. Perfect for removing rust from cutlery. Also ideal for all shiny parts of bicycles and motorcycles, as well as for glass and chrome parts and aluminum rims on cars. 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! Not suitable for Teflon or other non-stick surfaces. Use in wet condition only! Double-layered for extra strenght, extreme long lasting, washable in the washing machine at 60°C (please put in a line-sack or sock).
