The polished surface with artificial stones attached to a durable cotton cloth strongly removes kogation, burning and rust on pots and frying pans. It has an incomparable polishing power compared to metal scrubbing brushes and nylon scrubbing brushes. The stick type does not get dirty directly on your hands and can be used without worrying about rough hands. Because it is a sponge-bonded type, it can be easily washed even in narrow spaces and light uneven surfaces.
