Removing Hard Water Stains (1217)

A common problem in many homes is hard water stains. Stains on porcelain enamel and fiberglass fixtures--such as bathtubs and sinks--are a particular problem. Using an abrasive product like a pumice stone or powdered cleanser is not recommended.

If the product is abrasive enough to wear down the hard water stains, there is also a good chance it is abrasive enough to harm the surface of the fixture. Once the surface has been worn down or scratched, it is more susceptible to stain.

Use an acid solution to remove hard water stains. Mild acid products, such as vinegar or lemon juice, may successfully lighten stains. It is often helpful to soak a paper towel in the vinegar and place it on the stained area for 15 to 20 seconds. This allows the acid time to work before scrubbing with a nylon brush or white synthetic pad. Many commercial products on the market contain an acid solution for hard water stains. Read product labels and containers to find them. They will indicate if they are good for removing rust stains, hard water stains, or lime build-up. Always follow label directions carefully and be sure to rinse the surface after use. Remember, these products do contain fairly strong acids; they can be harmful if not used properly and with care
