To get rid of hard-water buildup on a faucet, try this natural solution: Cut a fresh lemon in half. With one of the halves, use your thumbs to gently open up the center. Then press the lemon onto the end of the faucet. Put a small plastic bag around the lemon and secure it around the faucet with a rubber band. Be sure that the rubber band it cinched tightly and that the lemon is around the end of the faucet. Leave the lemon in place for a few hours to allow the citric acid to work its magic.
After you remove the lemon, you may need to use a gentle scrubbing pad to wash off any loosened hard-water buildup. Then wipe the faucet with a damp cloth to remove any leftover lemon juice, and your faucet will be squeaky clean—and you didn’t need to use harsh chemicals!
