Tarnishing is a natural reaction when sterling silver is in the presence of salt water, air pollutants or everyday items that contain sulfur, such as leather, rubber and chlorine. To remove any tarnish, we recommend routinely wiping your sterling silver jewelry with the white side of a WUYIN polishing cloth. Regular wear of WUYIN sterling silver jewelry can also help prevent tarnishing.


To clean your jewelry, soak it in warm water with a little diluted dish soap and use a soft-bristle baby toothbrush to remove any dirt.

After cleaning, ensure the items are thoroughly dry by patting them with paper towels.
