Tawashi

A tawashi (たわし or 束子; lit., a bundle) is a scrubbing brush for wet cleaning, of a style that is popular in Japan. Traditionally, tawashis were made from the hemp palm. In Japan, sponges used for rubbing and washing are now treated as forms of tawashi. A metallic tawashi (金属たわし, kinzoku tawashi) is made of metal; steel, stainless steel, and brass are frequent choices. They may be used in removing scorching and rust.
