Sterling silver jewelry will naturally tarnish with time and wear. To present that jewelry should be stored in airtight plastic bag or jewelry box, it is also helpful to put an anti-tarnish strip in to the bags.
If tarnish needs to be removed, a polishing cloth or commercial silver cleaners may be used. For general cleaning, it is safe to clean your silver and gold jewelry with a soft babe toothbrush and common dishwashing liquid.
To protect your jewelry from damage we also recommend to not use your jewelry before activities such as gardening, exercise, housework, or when exposed to chemicals (bleach, household cleaners, pools, hot tubs, etc.).
To remove built-up tarnish from your silver, make a thick paste with 1/4 cup baking soda and 2 tablespoons water. Apply with a damp sponge and gently rub, rinse, and buff dry.
To polish gold jewelry, cover with a light coating of baking soda, pour a bit of vinegar over it, and rinse clean.
* Baking soda can be damaging to your jewelry so make sure to not leave it for to long in the solution and to clean thoroughly.
* Do not use this technique with jewelry containing pearls or gem-stones, as it could damage their finish or loosen any glue.
