The outer layer of the sponge is wrapped with a scrubber containing copper ions that have been specially processed. Copper ions can effectively inhibit the growth of bacteria, effectively preventing the common sticky bacteria and mold found in bathrooms and kitchens. Copper ions also allow thorough cleaning of dirt with only a small amount of dish soap or detergent.

Due to its specially processed surface, it is suitable for use on any surface without scratching, making it safe to use on non-stick cookware, enamel, glass, bathroom fixtures, cutting boards, induction cooktops, and more.
