To avoid tarnishing keep your jewelry dry. That means avoiding contact with chlorine, soaps, lotions, perfumes, hand sanitizers, cosmetics or cleaning products. Store your pieces in a soft cloth, protected from other items in your jewelry box or tray to avoid scratching. To clean, simply dip a lint-free, soft cloth in a warm bath of mild soapy water and gently rub. After you have cleaned, simply dry with a lint-free, soft cloth.
