Copper has a tendency to become tarnished over time. There are a few natural products you can use to help remove that unsightly stain. Mix the juice from several lemons with a tablespoon of baking soda to form a paste. Rub the mixture over the affected areas until the tarnish begins to come off. Once the tarnish is gone, polish with a clean cloth. Vinegar and salt also make an excellent tarnish remover. Pour vinegar and salt over the copper and rub vigorously until the tarnish is gone. Rinse and polish. You can also use lemon instead of vinegar. Use the juice from one lemon along with enough salt to form a paste. Follow the same procedure used for the vinegar and salt solution.
