The best way to maintain silver jewelry is to wear it every day, because human oil can produce a natural and moist luster. Contains exquisite three-dimensional silver ornaments made into sculptures to avoid deliberate polishing. If you find that the silver ornaments are yellow, you should first clean up the thin seams of the silver ornaments with a small jewelry brush, and then gently wipe the surface with a silver cloth to restore the original silvery white and brightness. I would like to suggest that if the silver cloth can recover about 80% silver, it is not necessary to use silver to wipe milk and wash water. Silver wipes contain silver maintenance ingredients and cannot be washed. If you don't handle and collect the silver jewelry after wearing it, it is very likely that the silver jewelry will turn black. At this time, you should use a small jewelry brush to clean the fine seams of jewelry, then drop a drop of silver emulsion on the paper towel to wipe off the black oxide on the surface of jewelry, and then use a silver cloth to restore the original brightness of jewelry. After that, remember to do daily general maintenance to prevent the silver ornaments from turning black again. Silver ornaments are hard to turn white after being blackened many times. The simple treatment method of electroplating silver jewelry is as follows: 1. First, buy a pack of alum from a nearby Chinese medicine store or drugstore; 2. Then use the silver jewelry you wear as; The proportion of boiling water (water must be boiled); 3. Take out the silver ornaments and put them in cold water. Use a soft brush (such as a toothbrush) dipped in toothpaste or laundry detergent or salad for cleaning. 4. Blow dry with a hair dryer, and then wipe with suede, which can be as bright as new silver. Its chemical properties are also relatively stable and its corrosion resistance is also very strong. However, sulfur, nitric acid and oxides in natural media such as air have a certain corrosive effect on silver. After wearing silver jewelry for a long time, sulfur and silver will combine to form a black silver sulfide film on the surface of silver jewelry, which will initially show as some tiny spots, and then spread into pieces to form what people usually call silver scales or silver molds, which will turn black and seriously affect the surface color of silver jewelry. When the silver ornaments have turned black seriously, the following methods can be adopted: (1): Sodium bicarbonate (commonly known as baking soda) is because aluminum reacts with sodium bicarbonate to release hydrogen, which can quickly reduce sulfide black spots to metallic silver and release sulfur. (2): Buy a pack of developing powder for developing photos, add 1kg water and stir it into a solution, soak the silver jewelry for 5min, then wash it with water and wipe it with a soft cloth. (3): Wash with 1% hot soapy water solution, then wet the surface with sodium thiosulfate solution, and then wipe with flannel, so that the silver ornaments can be cleaned. (4) As a cleaning solution, ammonia solution is widely used in traditional jewelry industry, but its effect is slightly inferior to that of phosphoric acid cleaning solution. What are the tips for maintaining silver jewelry? Silver jewelry is exquisite in workmanship and moderate in price, which is loved by most people. However, because silver jewelry is easy to oxidize, it will become dull after wearing for a long time. Therefore, the maintenance of silver jewelry is very important. For the maintenance of silver jewelry, there are the following points-some key points: (l) New silver jewelry For newly bought silver jewelry, a thin layer of colorless or extremely light nail polish can be coated on the surface, which is highly transparent, which is conducive to increasing its luster and delaying blackening. If you want to remove this layer of nail polish, you can soak it in banana oil, and then rinse it with clear water. (2) Treatment of slight discoloration For silver jewelry with slight discoloration of silver, it can be polished with decontamination powder or toothpaste; Or soak in sodium bicarbonate (i.e. baking soda) solution, and then clean and polish with a soft brush; You can also soak jewelry in a solution made of peeled and crushed Gleditsia sinensis, which contains soap and alkaloids, then soak it in boiling water and wash it with clear water; Or soak the silver jewelry in the soup of Platycodon grandiflorum Zhiyuan, and then wash it with clear water; It can also be soaked in oxalic acid solution with concentration below 50%. The use of all these methods can remove the slightly changed color on the surface of silver jewelry, making it as bright as new and as shiny as silver. (3) Silver jewelry with spots For silver jewelry with spots after being damp, you can dip it in warm vinegar, wipe it off with a soft cloth, and then wash it with water. It can also be polished with detergent, toothpaste or tooth powder. Usually, every 10 day, a layer of colorless nail polish can be applied to the silver jewelry to keep the luster and delay the discoloration. When wearing silver jewelry, pay attention to sweat, oil and moisture prevention. 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. How to maintain sterling silver jewelry? The biggest reason for the oxidation of silverware is oxygen in the air, so blocking the air is the best maintenance method. For example, put the silverware in a sealed plastic bag and then put it in a pearl box to block the contact between air and silverware. When the silverware is oxidized, you can use silver washing water or a piece of silver cloth to wipe it, but the silver washing water is more lethal, so please try to wipe it with a silver cloth unless you have to. If it is bright with silver water, it should be picked up immediately and rubbed gently to clean the chemicals on the surface.
