The copper cloth is well-known and can be used universally. 2-pack; 11 packs per tray Moist copper cloths can be used for stainless steel, glass ceramic (ceramic hob) or porcelain, kitchen sinks, most crockery and cutlery, etc. They also help with rust and limescale stains in the home. They should always be used with plenty of water, but you should use them without detergent or detergent, as otherwise a chemical reaction may occur with the copper and the cleaner. They have a natural antibacterial effect. Not suitable for painted or coated surfaces. They replace the classic dishwashing sponge or are a good help for stubborn incrustations/dirt and burnt things. Baking sheets (without coating) can also be easily cleaned again in no time at all!
