Tarnish is a product of oxidation, caused by the interaction of silver jewelry with certain elements such as oxygen or sulfur as well as with certain acids. Tarnishing on silver jewelry, when worn on a regular basis, usually does not occur. * Storage for a prolonged time causes silver jewelry to tarnish. * Contact with rubber bands may cause tarnish - the sulfur in rubber is a catalyst for tarnish. * Taking a medication that changes the acidity of your skin may cause silver jewelry to tarnish. * To keep your silver tarnish-free, frequently clean your silver in a mild dishwashing liquid diluted in water. * Thoroughly dry your silver jewelry after exposure to water. * Store silver in a dry container or a plastic bag with anti-tarnish paper. To remove tarnish or oxidation film from silver you can use fresh, uncontaminated commercial silver dip liquid, polish paste or polish cloth, available in supply or hardware stores. Make sure there are no loose stones or parts. Limit the gemstone's exposure to silver cleaners - cleaners may harm certain kinds of gemstones. Please read the cleaning product's instructions before cleaning. Thoroughly rinse jewelry after cleaning, and dry with a soft cloth until it's completely dry.
