How to Remove Rust Stains From Tub


Although this is not our area of expertise, we thought we'd pass on this information that was tested by our employees. They are always talking about their own home repairs and we thought this was an interesting topic and solution.
Rust in the bathroom is usually the result of two related situations. Either iron-containing metals in your bathroom fixtures have begun to rust OR your mineral-rich water supply contains iron particles and has begun to stain areas where water runs. This happens even with a porcelain tub as two of our employees found out.
Bleach and Tilex made the rust stains worse and they sparked another chemical reaction, creating more rust stains on the non-skid surface on the tub floor. Other products that either made things worse or didn't work at all: Lysol, toilet bowl cleansers, Soft Scrub, Goof Off, Awesome, Comet, Simple Green, Mean Green, Magic Eraser and CLR,
However, we found 2 things that really worked: Clorox2 and Hydrogen Peroxide. The Clorox2 worked best and required less scrubbing. Just pour either product on the stain and let it sit. Then scour gently with a damp sponge and rinse. If the stains are really bad you may have to repeat the process twice.

    How can I put a liquid product on a vertical or downward sloping surface and "let it sit"? It runs right down the drain.

    Cut a lemon into quarters and scrub directly on the rust stain... works like a charm!

    As the owner of an environmental housekeeping company I deal with this every day and the best, least toxic, and easiest solution to rust, hard water stains, etc on porcelain bathroom fixtures as well as the chrome fixtures is Barkeepers Friend. It has never failed to remove any stain we’ve ever used it on, we’ve even used it on glass shower doors to remove soap scum and hard water stains. It’s inexpensive, can be found in grocery stores and hardware stores everywhere and you’ll probably become addicted to it because it’s such a great product
