Black mold stains in the bathroom, especially black stains in the shower, are among the most frustrating cleaning problems at home. These dark marks appear on walls, grout lines and shower silicone. Even after careful cleaning, they often return in the same spots. Many people assume it is just surface dirt or a weak cleaner. However, in most cases the real cause is deeper. It is usually linked to organic buildup and persistent moisture in the bathroom.
