Steel wool
Steel wool, also known as iron wool or wire sponge, is a bundle of very fine and flexible sharp-edged steel filaments. It is the most common type of wire wool and is often the type meant when wire wool is mentioned. It was described as a new product in 1896. It is used as an abrasive in finishing and repair work for polishing wood or metal objects, cleaning household cookware, cleaning windows, and sanding surfaces.
