The faucet in my bathroom looked like it had a permanent white beard around the base. I scrubbed it with a sponge, then with a magic eraser, then with a brush, and the scale just laughed at me. Hard water stains are mineral deposits, and scrubbing alone will not dissolve them.

Acid will. And the easiest acid sitting in your kitchen is a lemon.

The Lemon Wrap

Cut a lemon in half and rub the cut side over the faucet, getting the juice on the scale. Then take a lemon half, cut side down, and wedge it against the stain so the juice stays in contact. Wrap it with a piece of plastic wrap or a small bag and leave it for ten minutes.

The citric acid dissolves the calcium and magnesium deposits while you do something else.

Scrub Gently After

After ten minutes, the scale should be soft. Wipe with a damp cloth or scrub gently with an old toothbrush. Most of it comes right off. I did not even need much pressure on mine, it lifted like wet chalk.

Rinse and Dry

Rinse the faucet with water and dry it with a clean cloth. Drying matters because standing water is what leaves new spots. I keep a small towel by the sink just for this.

If your stains are thicker, repeat the wrap once or twice. For really stubborn buildup:

• Soak a paper towel in lemon juice and wrap the faucet overnight
• Use a store-bought descaler for the worst cases
• Wipe the faucet dry after every shower to slow new deposits

The overnight towel trick is what finally cleared my bathroom faucet. It took one night and zero elbow grease.
