Removing Rust Stains Using Oxalic Acid
Oxalic acid is a dry material that closely resembles sugar. Once dissolved in water, it effectively removes rust and other oxidation from surfaces. It is a mild acid that requires the use of rubber gloves when it is handled.
What You'll Need Before You Start:
- Hot tap water
- Oxalic acid
- Rubber gloves
- Clean, white towels
Put on the rubber gloves and fill a plastic bucket with one gallon of hot water. Pour in approximately 1/8 cup oxalic acid crystals. Avoid inhaling any of the dust from the crystals or the fumes from the mixture. Once the crystals dissolve, you are ready to remove the rust stains from the tub.
- Dampen a clean, white towel in the oxalic acid mixture.
- Generously sponge the cleaner onto the rust stains.
- Allow to penetrate for five minutes.
- Reapply the acid until the stains are removed.
- Rinse the tub thoroughly using warm water.
While it is not necessary, it would be a good idea to thoroughly clean the tub with a mild dishwashing liquid to ensure that all of the acid is completely removed before the tub is used.
We often turn to our bathtubs as a nice way to relax after a long, hard day. The last thing you want to see in your tub is brown stains. Acids dissolve the rust stains, allowing you to relax in a clean, white tub. Cleaning rust stains as they first appear results in quick and easy removal. However, even difficult rust stains can be removed with the proper products.
