Always remove your jewelry before swimming, playing sports, using harsh chemicals, applying beauty products or entering extreme temperatures. Store silver jewelry in an airtight plastic bag to avoid tarnish. If your piece needs to be polished, use a dry rouge cloth on high polished areas and a toothbrush and baking soda to clean matte areas, but not oxidized areas. Dips such as Tarn-X can be used, but be careful to avoid contact with delicate gemstones such as opal and pearl and also oxidized areas, as the harsh chemicals can damage stones and strip oxidation.
