Mineral stains--such as copper or rust--are something that most people have to deal with at one time or another. Hard water can cause a build-up of mineral scale in your bathtub and sink. These stains will make your bathtub look old and dingy. And no one wants to take a bath in a dirty-looking tub. However, there are some home remedies that can remove copper stains and restore the look of your bathtub.
Purchase a pumice stone. Pumice stones can be found in the beauty section at your local department store.
Rinse the pumice stone under warm water. The stone will soften.
Scrub the copper stain with the pumice while lightly applying pressure. The pumice stone will start to rub off onto the bathtub and leave behind a thin coating. This coating is essentially mud and will wash off easily with water.
Rinse the bathtub with water.
Repeat the process if necessary.
Combine equal parts water and ammonia.
Pour some of the mixture onto the copper stain. Allow the mixture to sit on the stain for 10 minutes.
Saturate a cloth or sponge in the mixture.
Scrub the copper stain with the cloth or sponge until the stain is gone.
Rinse the bathtub thoroughly.
Saturated wash cloths or paper towels with undiluted vinegar.
Lay the saturated cloths on top of the copper stains.
Allow the cloths to sit on the stain for a few hours.
Rub the copper stain with the saturated cloths. Add more vinegar if necessary.
Rinse the bathtub with water. Repeat if needed.
Create a paste by combining baking soda and water.
Apply the paste to the copper stain.
Allow the paste to sit on the stain for a few hours.
Scrub the paste into the stain using a sponge or plastic mesh pad.
Rinse the paste away with water. Repeat if necessary.
Combine hydrogen peroxide with cream of tartar to create a thick paste.
Spread the paste on to the copper stains.
Allow the paste to sit for at least 30 minutes.
Rub the paste into the stain with a soft cloth or sponge.
Rinse the bathtub with warm water.
