Regularly cleaning your bathroom shower removes mold and mildew and soap scum that makes a bathtub or shower look dirty. Not all shower materials are the same, and some cleaners may be harmful to a shower surface. Different cleaners and cleaning methods are necessary for tile, fiberglass, and natural stone (including marble, limestone, and travertine), as well as the shower faucets and shower head, glass shower doors, shower curtains, and the shower drain. Learn how to clean a shower safely and correctly and the best cleaners for each surface type.
