Answer

Hydrochloric acid (HCl), particularly in diluted form, is often called "bathroom acid" or "toilet acid" because it's a common ingredient in toilet bowl cleaners and bathroom cleaning products. The acid effectively removes mineral deposits, lime scale, rust stains, and hard water buildup from bathroom fixtures. Commercial bathroom cleaners typically contain 5-10% hydrochloric acid, though they may be marketed under names like "muriatic acid" in hardware stores.
