We have a problem cleaning water spots off tub and shower glass surrounds. Someone even suggested, of all things, oven cleaner. Any suggestions?


To remove mineral deposits from glass, porcelain and chrome you will need a safe acidic cleaner - normally phosphoric acid formulated as a lime and scale remover. Protect any vulnerable areas such as carpet, and wear gloves and goggles when applying the acid. Do not mix with any other chemicals. Begin scrubbing with a white nylon pad and observe the results. Make sure the scouring pad does not scratch the surface. Squeegee or wipe off the residue and observe the results. Repeat until mineral deposits are removed. Finally, rinse with water and polish dry.
