How to remove corrosion on bathroom faucets

Brass and copper content in water can cause metal bathroom faucets to corrode. Scratched or damaged metal faucets exposed to water, oxygen and carbon dioxide also develop corrosion. Corrosion produces reddish-brown scale on bathroom faucets that is aesthetically unappealing. If left untreated, corrosion can spread through a faucet until it weakens and becomes permanently damaged. Promptly remove corrosion to preserve a faucet's appearance and structural integrity. Fortunately, basic supplies can effectively eliminate corrosion on bathroom faucets.

Dampen a soft, clean cloth with warm water. Wipe the cloth over the faucet to remove loose dirt, grime and debris.

Fill a plastic bowl with 60 ml (1/4 cup) of salt and 36 ml (2 tbsp) of lemon juice. Thoroughly mix the ingredients to form a paste the consistency of icing.

Spread the paste evenly onto the corroded area of the faucet. Keep the paste on the faucet for 30 minutes.

Scrub the faucet with a nylon bristle brush to loosen the scaly debris.

Dampen another soft, clean cloth with warm water. Wipe the damp cloth over the faucet to rinse away the paste and loose corrosion.

Wipe the faucet with a terrycloth towel until thoroughly dry.

Repeat the process if any trace of corrosion remains on the faucet. Make sure all corrosion is completely removed.


You can substitute borax for the salt. You can substitute white vinegar for the lemon juice.


Do not leave even a speck of corrosion on the sink; the corrosion will spread and cause more damages.
