A scrubber is a tool used for cleaning surfaces. It is made up of three components: a scourer, a loofa, and a BRUSH. A scourer is a metal or plastic mesh pad used to remove dirt and grime from surfaces. A loofa is a sponge-like material made from the fibrous skeleton of a plant, which is used to scrub surfaces. Finally, a BRUSH is a tool with bristles that is used to sweep away dirt and debris. Together, these three components make up a scrubber, which is used to clean surfaces.
