Porcelain and enamel are very hard, but harsh abrasives and acids will damage them. Abrasive cleaners make tiny holes in porcelain and enamel, then when dirt gets into these holes you will need to use more abrasive cleaner to clean your bathtub. After repeated uses, this abrasive cleaner will wear away the surface. A porcelain or enamel tub can last many years, if you are careful about how you clean it.
