How to classify silver jewelry: In addition to pure silver jewelry, there are black silver jewelry, hidden silver jewelry and colored silver jewelry. \x0d\ As we all know, silver ornaments often turn black, yellow, lose luster and sometimes even deform. But as long as you put some thought and use your brain, you will definitely make your baby last as long as new! \x0d\ Symptom analysis 1: Loss of luster \x0d\ Because of what clothes to wear and what jewelry to bring, girls always wear the same clothes every day. If you don't wear it for a while, it will become boring. This is because the copper contained in jewelry will rust when it comes into contact with air. The solution is also very convenient, as long as it is wiped with silver cloth, the jewelry can be kept bright and white. Some jewelry surfaces are protected by platinum, but under the wear and tear of long-term wear, the silver under them will still be slowly exposed to the air. Experts suggest that rubbing with baking soda powder can also restore the luster of silver jewelry, which is natural and cheap. \x0d\ Symptom analysis 2: Yellowing \x0d\ If the silver jewelry shows signs of yellowing during wearing, it is also the cause of oxidation. First, use a small jewelry brush (toothbrush can also be used) to clean up the dirt in the tiny gaps of the silver ornaments, and then gently wipe the surface with a silver cloth to restore the original silvery white and brightness of the silver ornaments. Here, I suggest you: if you can restore about 80% silvery white with silver cloth, you don't need to use silver washing water and other scrubbing products. Because these products are corrosive, silverware will turn yellow more easily after using these products. Remember that silver cloth contains maintenance ingredients and must not be washed. \x0d\ Symptom analysis 3: Blackening \x0d\ If you don't handle and collect the silver ornaments after wearing them at ordinary times, it is very likely that the silver ornaments will be blackened. At this point, the jewelry should be thoroughly cleaned first, then dipped in a little silver lotion with paper towels or cotton cloth to wipe off the black oxide on the surface of the jewelry, and then the original brightness of the jewelry should be restored with silver cloth. After that, remember to do daily maintenance to prevent the silver ornaments from blackening again, because it is difficult for the silver ornaments to turn white after blackening many times. \x0d\ Please note: \x0d\ Keeping the silver ornaments dry during daily wear is the key. Don't wear swimming, close to hot springs and seawater. Wipe the surface gently with cotton cloth or paper towel after each wear to remove moisture and dirt, and then store it in a sealed bag to avoid contact with air. At the same time, don't wear other precious metal jewelry when wearing silver jewelry to avoid collision, deformation or wear. \x0d\ A really good idea: \x0d\ There are many ways to clean and maintain silver ornaments. Besides toothpaste, wearing it every day is the best way to maintain silver jewelry. When wearing, the grease produced by human body adheres to the surface of jewelry, which can avoid the direct contact between silver jewelry and air and reduce the signs of blackening and yellowing.
