The Libman Swivel Grout and Scrub Brush is a great tool for tough scrubbing without bending over. The design of the brush makes it easier to get tough grime out of any kitchen, bathroom, or between flooring tiles. The head of the brush has V shaped fibers. The head can swivel up to 180 degrees in order to reach into grout, corners and other tight areas. In addition, the head has built-in scrapers to help remove stuck on debris. The narrow brush is made of extra durable, recycled PET, staple-set fibers to form an ultra-stiff brushing surface. Replacement brush heads pair with the Swivel Grout & Scrub Brush with handle.
