Precautions for jewelry maintenance 1. Avoid contact with chemicals: Alloy jewelry is easily oxidized when in contact with chemicals, so it should be avoided as much as possible. 2. Use warm water when cleaning: Use warm water when cleaning alloy jewelry. At the same time, do not immerse the jewelry in water for too long, so as not to affect the surface texture of the jewelry. 3. Avoid friction and collision: Alloy jewelry is easy to scrape and deform, so when wearing jewelry, be careful to avoid friction and collision with hard objects. 4. Store jewelry properly: When not wearing alloy jewelry, put it in a dry box or bag to avoid contact with air and oxidation.
