Removing stains from a tub will depend on two factors: type of mineral causing the stain and the material the tub is made from. Porcelain is the most popular type of bathtub surface and is more forgiving. You can use any of the methods described below to remove common bathtub stains on porcelain. If you have an acrylic tub, do not use abrasive cleaners because they can damage the surface. Here’s How To Clean with Bleach In a Bathroom.
