While an interior cleaner and microfiber towel can remove grime from the surface, there can be times where we need more cleaning power. The Interior Scrubbers offer a bristle-type nylon material that allows you to deep clean interior surfaces like plastic, leather, and vinyl. The black and white color on each side are the same material, which helps you keep track of each side used. Pair this scrubber with your favorite interior cleaner and wipe away any residue with a clean microfiber towel. Safely and easily clean various interior surfaces with the Koch Chemie Interior Scrubber!
