Cleaning brushes use bristles, wire, or other filaments to scrub and clean kitchens and bathrooms, spot dust and clean surfaces, and remove deposits, metal, paint, and residue from equipment. Scrub brushes apply direct pressure to remove stubborn food, dirt, and grime from counters, tables, conveyor belts, decks, walls, tanks, and vats. Wire scratch brushes vigorously scrub and remove paint, rust, scale, and other stubborn residue from metal parts, heavy equipment, and grills. Pipe and tube brushes clean the inside and outside of pipe, tubing, elbows, tees, valves, drains, and smooth and threaded blind holes.
