These durable copper cloths effortlessly clean a variety of surfaces including pots, pans, sinks, ovens, ceramic cooktops, glass, stainless steel, and more. Despite their strength, they are gentle on delicate surfaces thanks to their soft, non-abrasive copper threads. Make sure to ALWAYS use them wet, with warm, soapy water for optimal results. They are also suitable for removing rust from cutlery and polishing glass, chrome, and aluminium rims on cars, bicycles, and motorbikes.
