Sterling Silver Jewelry
The best way to prevent tarnishing (oxidation) when not wearing your sterling silver jewelry is to store your clean, dry pieces in a dry, airtight container and keep items separate to prevent tangling and scratching. Avoid leaving your jewelry in that bathroom, as the moisture will speed up the oxidation process. Minimize your jewelry's contact to chemicals (lotion, hairspray, bleach, perfume, etc) to best maintain its shine.
To clean your sterling silver jewelry, use mild soap and water, a sterling silver polishing cloth, or a sterling silver jewelry cleaning solution. If using a cleaning solution, be careful to follow the directions and don't leave the jewelry in for too long.
Gold Filled / Gold Vermeil Jewelry (Yellow and Rose Gold)
To prolong the life of your jewelry, do not wear your gold filled or gold vermeil jewelry in the shower, or when swimming or exercising. Minimize your jewelry's contact to chemicals (lotion, hairspray, bleach, perfume, etc) to best maintain its shine. To store your gold filled / gold vermeil jewelry, wrap clean, dry jewelry in a dry, soft cloth and keep items separate to prevent tangling and scratching. To clean, mix mild soap, a drop of ammonia, and warm water. Gently swish the jewelry to clean, and then dry with a soft cloth (non-abrasive), and let it dry thoroughly.
