Question 2: When the silver turns black, what can be used to wash the white toothpaste and brush it with a toothbrush?
Question 3: How can I wash the silver white? It is very convenient to wipe with toothpaste now. In the countryside, I saw someone throw a silver bracelet into the water to feed the pigs, and it turned white the next day.
Question 4: What method can be used to clean the blackened silvery white? Gold products are more expensive and are often used as decorations. After the gold and silver products become dirty, don't wipe them with rough things. Use a piece of velvet with delicate texture and wipe it with egg white. The gold and silver products are as bright as new. If the surface is seriously blackened, you can wipe it with egg white mixed with a spoonful of bleach. You can also soak the gold and silver products in low-concentration bleach or small K water and rinse them again overnight. Follow the above method and the effect is also very good!
Many friends like sterling silver ornaments, but they don't know how to maintain them. In fact, we only need to spend some time in our daily life to make silver ornaments last as long as new.
1, the best way to maintain 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.
Keep the silver ornaments dry, don't wear them to swim, 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.
If the silver ornaments show signs of yellowing, 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. (If the silver cloth can restore about 80% to 90% of silver, don't use silver lotion and silver washing water, because they are corrosive to some extent, and silver ornaments are more likely to turn yellow after using these products. In addition, silver cloth contains silver maintenance ingredients and cannot be washed with water)
5. The silverware is seriously yellowed, so it should not be soaked in silver washing water for too long, usually in a few seconds. Rinse with clear water immediately after taking it out, and then dry it with a paper towel.
Common surface treatment methods of 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 silver jewelry is electroplating. At present, the commonly used methods are silver plating, rhodium plating, palladium plating and so on.
The silver jewelry produced by European goldsmiths mainly adopts deep oxidation treatment and sandblasting electroplating treatment.
Common knowledge of silver jewelry maintenance
Many people like silver ornaments, but they don't know how to maintain them. They even think that silver ornaments are difficult to maintain, which is 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.
When wearing silver jewelry, don't wear other precious metal jewelry at the same time to avoid collision, deformation or wear. Keep the silver ornaments dry, don't swim in them, and don't go near 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.
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 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 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, you should remember to do the daily general maintenance to prevent the silver ornaments from turning black again. Silver ornaments are difficult to rub white after many blackening.
These are some basic considerations. Here is a detailed introduction to the maintenance methods of electroplated and unplated silver ornaments:
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 silver ornaments, that is, the inner layer is pure silver, and the surface is being treated with current; Electroplating I >>
Question 5: How to wash the silver jewelry when it is black? Use special silver cleaning water. If you are afraid of being expensive, you can also wash it yourself at home. Add some salt to a small cup, and then add it to half a glass of water. After soaking the silver jewelry for half an hour, wash it with clear water to make it white.
Question 6: How to wash the silver jewelry when it turns black? At present, there are some discoloration phenomena of silver jewelry due to oxidation. Here are some suggestions:
Or treat the blackened silver ornaments in the following ways-
(1) Wipe with cotton dipped in white vinegar, black silver sulfide will dissolve in ester acid, and silver jewelry will glow again.
(2) Wipe with alcohol or sodium carbonate, and the effect is also very good.
(3) Wash the surface of ornaments with detergent, then with sodium thiosulfate solution (prepared by adding 20g sodium thiosulfate into 100g water), and then with clean water.
(4) mixing l parts of tartaric acid, 1 part of alum and 10 part of salt, heating to boiling, and soaking jewelry; /kloc-take it out after 0/0 minutes, wash it with clear water and dry it.
(5) Washing the mirror with ammonia water or squeezing toothpaste on the flannel can also restore the original luster.
Of course, it is also very important for the usual maintenance. I hope the following points are useful to you:
Maintenance of silver jewelry:
1, to avoid collision deformation or scratches. Even with different fashions, silver ornaments will oxidize and change color after a long time.
2. Avoid contacting pure silver ornaments with water vapor and chemicals, and avoid swimming with them, especially when going into the sea.
3. Wipe it clean with cotton cloth after wearing it every day, and put it in a jewelry box or bag for sealed preservation.
4, jewelry has been oxidized to black, you can use a soft brush dipped in toothpaste to scrub; you can also use hand soap or detergent to clean: it is really not possible to scrub with silver washing water before cleaning: jewelry should be dried with cotton cloth after washing.
5. Avoid contact with chemicals such as acid and alkali.
6. Please wear jewelry after spraying perfume and hairdressing products.
7. When taking a bath, take off the ornaments and avoid contact with shower gel, soap and other supplies.
8. Please take off your jewelry when you sleep, and avoid wearing it overnight, and your hair will be entangled in the jewelry.
9. Sweat of human body will corrode silver jewelry, so it is best to wash it with clear water after wearing it in summer and keep it dry.
10, pure silver is soft, so be careful on weekdays to avoid rubbing against hard ornaments.
1 1. Please wipe the ornaments with a soft cloth after each wear.
12, the jewelry box is stored in the dark.
Question 7: What can be used to wash white when silver is black? Wipe the surface of silver ornaments with professional silver wiping cloth first (except platinum plating process).
Second, with professional silver washing water, you can use soaking method (except the old process) or wiping method (except the platinum plating process and inlay process), put the silver ornaments in the silver washing water for about three seconds (if the oxidation is particularly serious, it can be put for a longer time), take them out and rub them repeatedly, rinse them with plenty of water, and rub them in alkaline water (such as soapy water); Finally, rinse with clean water.
Third, use toothpaste (try to choose a green and transparent rice grain shape with fine particles to avoid scratching the surface of the silver jewelry), directly rub the toothpaste on the silver jewelry, and then add a little water to rub out the foam. If there is a seam, brush it with a toothbrush to prevent foam from entering the seam.
Special note: If it is a stone inlay process, avoid washing with water to prevent the stone from falling off. It is recommended to clean with silver cloth.
In addition to the advantages of beautiful color and reasonable price, it should be noted that silver jewelry will turn black if worn for a long time. This is because silver reacts with sulfur in the air to produce black silver sulfide, which affects the appearance. If it has been oxidized and blackened, it can be dipped in silver washing water or wiped with a silver cloth. You can also scrub with a soft brush dipped in toothpaste and dry it with cotton cloth after washing.
The most practical method is to use a toothpaste brush, but be sure to dry it.
Question 8: When the silver is washed white, how does the area turn black? It is normal for silver to be washed white and turned black after wear. Silver oxidizes easily in the air, which may also be related to your constitution.
Question 9: It is black with old silver. Because the surface is oxidized to produce silver oxide, is there any way to wash the silver black? If it is pure silver, it can be soaked in dilute sulfuric acid, but not nitric acid. Nitric acid will react with silver, and silver chloride precipitate generated by hydrochloric acid will adhere to the surface, and the effect of vinegar is not as good as dilute sulfuric acid; If it is silver plating, it is recommended not to wash it unless it can be plated again.
Question 10: How to wash the silver ornaments? If the silver ornaments show signs of turning yellow and black, generally wipe the surface with a silver cloth to restore the original silvery white and brightness of the silver ornaments. If 80% silvery white can be recovered by wiping cloth with silver, don't wash water with silver, because these products are corrosive. Silver cleaning cloth contains silver maintenance ingredients and cannot be washed. If it turns black seriously, or the three-dimensional sculpture style is not easy to rub, you can use silver washing water to clean the silver ornaments, which can basically solve the problem.
In addition, there is a little trick to brighten the silver ornaments, which is put forward here for your reference: if you want to brighten the newly bought silver ornaments and avoid blackening, you can apply a thin layer of transparent nail polish on their surfaces, and then apply it again every ten days. If you want to remove nail polish, you can soak it in banana oil (nail polish remover) and then wash it with clear water.
Why silver turns black:
Silver has stable chemical properties and strong corrosion resistance. However, sulfur, nitric acid and oxides in natural media such as air have a certain corrosive effect on silver. Silver has been in the air for a long time, sulfur and silver combine to form a black silver sulfide film on the surface of silver, and some tiny spots begin to appear, and then spread to life, forming what people usually call silver scales or silver molds, turning black.
Maintenance of silver jewelry;
1, the best way to maintain 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. Never wear silver jewelry for bathing, swimming (especially in hot springs and seawater), perfume, hair gel, beauty, hair dyeing, soap, shampoo, etc. , will make the silver chain black, corrosion, peeling off, because some chemicals will immediately make the silver jewelry discolored, which is different from the general natural oxidation. It can't be cleaned with silver cloth and silver water. If the platinum layer on the surface of electroplated silver jewelry fades, it will appear dark black.
4. Wipe the sweat and stains on the surface with a soft cotton cloth after wearing it every day. If you sweat a lot, wash it every day. Put it away when you don't wear it at ordinary times. It is best to pack it in sealed plastic bags, keep it dry and away from light, air and moisture!
5. Silver jewelry is a delicate article, so you need to be careful when using it. Before going to bed, taking a bath and changing clothes every day, please take off your jewelry to avoid it being broken and squeezed by external forces. Try not to pull the silver jewelry hard at ordinary times, otherwise it will be easily deformed and broken. Although the most common 925 silver is much stronger in hardness than 999 silver, it should also be taken care of and maintained by high-grade jewelry. In particular, machine-made chains (such as star chain and octagonal snake chain) are carefully made, so be careful when taking them down to avoid breaking them.
