  • When wearing:
    • Be sure to keep it dry and avoid wearing it while swimming, soaking in hot springs, or getting close to hot water and pool water, as this can lead to oxidation.
  • When not wearing:
    • Wipe it with cotton or paper towels before sealing it for storage. Avoid exposure to air to prevent oxidation and tarnishing.
  • If oxidized:
    • Use a silver polishing cloth, or brush lightly with toothpaste to clean the surface. Severe oxidation should be treated with silver washing liquid.
