Sterling silver will oxidize when exposed to the elements, so remove your jewelry before exercising, washing your hands or showering.

Polish gently with a silver cloth to clean tarnished sterling silver jewelry.

Keep sterling silver jewelry in a resealable bag and store it in a dry place when its not worn to protect it from the elements of daily exposure.
