When wearing silver ornaments, human sweat contains sulfur, ammonia and so on. Moreover, the air also contains hydrogen sulfide, nitric oxide and other substances, which will lead to the oxidation of the surface of silver ornaments, and then change color and lose luster. The blackening of silver ornaments is also related to the acidity and alkalinity of human sweat. Sweat is acidic, and silver ornaments will turn black faster, regardless of health or not. Sterling silver jewelry will be marked.
Many friends like sterling silver jewelry, but they don't know how to maintain it. In fact, we only need to pay attention to the following points:
1, the best way to maintain sterling silver jewelry is to wear it every day, because human oil can produce a natural and moist luster.
2. Don't wear other precious metal jewelry when wearing silver jewelry to avoid collision, deformation or wear.
3. Keep the sterling silver ornaments dry, don't swim with them, and don't go near hot springs and seawater. When not in use, you can gently wipe the surface with cotton cloth or paper towel to remove moisture and dirt, and put it in a sealed bag or box to avoid contact with air.
4. If you find signs of yellowing in sterling silver jewelry, the easiest way is to gently wash the surface with toothpaste and some water. Or use a small jewelry brush to clean up the fine seams of the silver ornaments, and then gently wipe the surface with a silver cloth, and the original aesthetic feeling of the ornaments can be restored immediately.
5. Sterling silver jewelry is seriously yellow. It is not advisable to soak in silver washing water for too long, usually for a few seconds. Wash it with clear water immediately after taking it out, and then dry it with a paper towel.
6. If the silver cloth can recover about 80% silver, there is no need to use silver lotion and silver washing water, because these products are corrosive to some extent, and the silver ornaments will turn yellow more easily after using these products. Silver wipes contain silver maintenance ingredients and cannot be washed.
