How to Remove Green Water Stains on a Faucet

Green stains on your faucet occur as a result of minerals in the water. When you have hard water, these stains build up slowly over time. The more the stains build, the more time consuming it is to remove them. Use supplies found readily around the home to remove green water stains and keep them from returning. Acidic cleaners, both natural and commercial, are most effective when it comes to removing these unsightly stains.

Slice a couple of fresh lemons in half. Rub the lemon juice and pulp over the green water stains on your faucet. Allow the acid in the lemons to work at loosening the green stains for 10 minutes.

Dampen a pad of fine steel wool. Rub the lemon juice and pulp on your faucet with the steel wool pad. Rinse the pad, and continue to remove as much of the green stains as possible.

Mix white vinegar and baking soda in a bowl to make a mineral deposit removing paste. Scoop some of the paste onto a damp cleaning cloth.

Scrub remaining water stains with the natural paste. Rinse your faucet with water, then continue to scrub until the rest of the green stains are gone.

Dry the faucet with a clean cloth.


Keep water stains from returning by spraying your faucet and sink with undiluted vinegar once or twice per week. Wipe the surfaces with a dry cloth.


Avoid abrasive scouring cleansers when removing limescale or hard water stains. These cleansers can scratch your faucet or sink surface, leaving permanent grooves where stains can form.
