How to Clean Bathroom Caulk With TSP

Trisodium phosphate (TSP) is a household cleaner with powerful degreasing agents. It is known as an all-purpose cleaner for use on many areas in the home, including the kitchen and bathroom. Keeping a bathroom clean includes cleaning grout and caulk lines around showers and bathtubs where mold and mildew create dark, black stains. TSP is effective in removing mold and mildew, helping restore the bathroom to its original, fresh look.
