Maintenance of sterling silver jewelry;
1. When not in use at ordinary times, it should be sealed and stored. Can be packed in a small plastic bag, isolated from the air, reduce the chance of oxidation, and keep the ornaments fresh.
2. Alloy ornaments such as silver ornaments should be as far away from water and irritating liquids as possible. Take off the silver ornaments when washing hot springs, and wear them when bathing and swimming at ordinary times. However, it is necessary to avoid contact with sulfur soap, hair dye, perm agent and other items that are easy to damage the surface luster of silver jewelry.
3. Pay special attention to the silver ornaments inlaid with stones, and try not to get wet, because there will be gaps in the mosaic joint, and the stones will easily fall off when they meet water.
4. For smooth ornaments, you can generally wipe them with delicate paper towels or soft cloth, and gently wipe them back and forth in the same direction to avoid too many scratches. The best effect is to use professional silver cloth.
5. The silver ornaments of the old craft can be polished with silver cloth or toothpaste, and the brightness can be restored. Remember not to use silver washing water to clean, otherwise it will destroy the old process above.
Extended data:
Generally, the pure silver ornaments sold in the market are 925 silver, not 999 pure silver, because 925 silver is alloy silver made by adding other metals, and such 925 silver is also internationally recognized as pure silver, with a ratio of 7.5% alloy to 92.5% silver. Jewelry forged with this pure silver is stronger and less prone to wear and deformation. The real 999 sterling silver is as soft as pure gold and is made of alloy sterling silver.
