Abrasive cloth is a type of material used for cleaning and polishing surfaces. It is made up of four components: EMERY, Pumice, GRIT, and SCRAPER. EMERY is a hard rock composed of corundum, magnetite, and other minerals. Pumice is a light-colored, porous volcanic rock that is used as an abrasive. GRIT is a form of sandpaper made from crushed or synthetic materials. Finally, a SCRAPER is a tool used to scrape off dirt and debris from surfaces. Together, these components make up abrasive cloth, which is used to clean and polish surfaces.
