Tips on keeping sterling silver jewelry from tarnishing Over time, any sterling silver jewelry piece exposed to air will tarnish. Sterling silver is 92.5% silver and 7.5% other metals. It's the other metals, primarily copper, that cause sterling silver to tarnish. The copper reacts to moisture and sulfur in the air, causing the tarnishing reaction. Silver tarnishes faster in areas with high humidity and air pollution. Chemicals like hairspray, perfume, deodorant, body lotion, bleach, etc., can speed up the tarnishing process. Be also mindful to keep silver away from rubber, vinegar, olives and fruit juice. Store your sterling silver jewelry in a cool, dark place away from sources of sunlight, heat and moisture. To reduce scratching and tarnishing, store your pieces individually in small zip-lock plastic bags, removing as much air as possible. You may also want to put a small strip of anti-tarnish paper in each bag with the jewelry. Don't leave silver jewelry in the bathroom unprotected, and do not wear it the shower, swimming pool or hot tub. Humidity and moisture can make tarnish appear faster! After taking off your silver jewelry, clean it with a dry soft cloth, or polishing cloth, before putting it back into an airtight container. If the polishing cloth doesn't remove all the tarnish, wash silver jewelry (without gemstones or pearls) in warm water with a few drops of mild dish washing liquid. Immerse the sterling silver in the water and gently hand wash. Use a cotton swab for tight corners, or soft baby toothbrush can be used for more abrasive cleaning if needed. Rinse thoroughly.
