● Many people like silver ornaments, but they don't know how to maintain them. They even think that silver ornaments are difficult to maintain. That was not the case. The chemical properties of silver are not as stable as platinum and gold, and it is often oxidized to black or yellow by water or other chemicals in the air, losing its luster. After understanding this feature, we only need to spend a little thought in our daily life to make the silver ornaments we wear last as long as new.
● Don't wear other precious metal jewelry when wearing silver jewelry to avoid collision, deformation or wear.
● Keep the silver ornaments dry, don't swim in them, and don't get close to hot springs and seawater. After each wear, you can gently wipe the surface with cotton cloth or paper towel to remove moisture and dirt, and then put it in a sealed bag to avoid contact with air.
● 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.
● When silver ornaments are not often carried, some surfaces will rust, because they contain a small amount of copper, and most of them can remain bright and white after polishing with silver cloth; In addition, the treatment of fine plating white K strengthens the protective layer on the surface, but after long-term wear, the silver under it will still be slowly exposed to the air. It is suggested to grind and wipe with baking soda powder, which can restore the luster of silver jewelry, naturally and cheaply.
● If the silver ornaments show signs of yellowing, first clean 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 of the silver ornaments. I suggest that 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 silver ornaments are more likely to turn yellow after using these products. Silver wipes contain silver maintenance ingredients and cannot be washed.
● If the silver ornaments are not treated and collected after wearing, it is very likely that the silver ornaments 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.
Question 2: The silverware becomes discolored. How to clean it? 1, Reasons for black and yellow sterling silver and common sense of maintenance: 925 silver plated with platinum is an unstable metal, which will turn yellow and black due to external factors. There is no way to stop it from changing in the world at present. Plating platinum (palladium and rhodium) on 925 silver can effectively isolate 925 silver from the outside air. This platinum effect can generally be achieved according to different protection procedures of jewelry.
925 silver, pure silver and highly polished silver mine shines beautifully bright white (milky white) when it is first mined, but once it comes into contact with air, it will turn silver (beige white) in a short time. After the finished product is produced, the bright white of newly mined silver can be reproduced by high polishing or silver plating, but it cannot be kept in the air, and it will return to its original state in about 15 days.
925 pure silver 925 pure silver is silver with a silver content of 925 per thousand (92.5%). Different from the traditional pure silver, in order to strengthen the hardness of silver ornaments, about 7.5% copper is added, so the silver of 925 silver will appear gray silver instead of traditional silver. Silver is an unstable metal. The oil on the surface of a healthy human body can keep its natural color. If it is worn for a long time and exposed to the air, it will turn yellow. As soon as it touches chemicals (such as hair gel and soap) with toxins or "sulfur" deposited in the body, it will suddenly turn black. Therefore, whether wearing silver ornaments can effectively maintain its true colors is also a manifestation of good health.

These are some basic considerations. Here is a detailed introduction to the maintenance methods of electroplated silver jewelry and unplated silver jewelry.
The easy oxidation of silver is its weakness, and it is also a headache for consumers and producers. At present, the common silver surface treatment methods in the domestic market are further oxidation, electroplating and untreated.
Whether it is further oxidized or untreated, the characteristics of silver oxidation blackening are fully utilized. Using oxidants to deepen the oxidation of the silver surface, or using the natural oxidation of the silver surface to produce richer colors and mechanism effects in silver jewelry, so that the defects are not concealed, is a method of exerting strength.
The real way to prevent the surface oxidation of pure silver jewelry is electroplating. At present, the commonly used methods are silver plating, rhodium plating, palladium plating and so on.
First of all, it is necessary to distinguish whether there is electroplating (silver ornaments are generally divided into electroplating and non-electroplating):
There are electroplated pure silver ornaments, that is, the inner layer is pure silver, and the surface is being treated with current; Electroplating is generally divided into electrogold and platinum; The way to identify electroplating is that its surface is brighter than pure silver, just like a mirror, which has good reflective effect and is not easy to oxidize (the oxidation time depends on the thickness of electroplating). Electroplated sterling silver ornaments are easy to be lost due to vulcanization ... >>

Question 7: How to clean silver jewelry when it comes into contact with bleach? The main component of disinfectant is sodium hypochlorite, which is a strong oxidant. When it comes into contact with silver, it will oxidize the surface of silver and generate a layer of black silver oxide.
