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 2: How can silver be washed 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 3: How to wash white when silver is black? The easiest way is to use toothpaste. I often wash with toothpaste, and the effect is quite good. In addition, silver can absorb internal heat very well. Your silver is black, which means you are not in good health now. Please pay attention.
Question 4: How to wash the silver bowl black? Squeeze out some toothpaste and wipe with a soft cloth.
Question 5: 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 6: How to wash 925 silver If the silver ornaments show signs of yellowing and blackening, generally wipe the surface with a silver cloth to restore the original silvery white and brightness. 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.
Question 7: How to wash white (clean) gold and silver after it turns black? The simplest thing is to use toothpaste.
1. Wipe it clean and put it away.
If you don't wear silver ornaments for a long time, some silver ornaments will have copper rust on their surfaces. This is because they contain a little copper. You must wipe it clean with a silver cloth to prevent sweat stains from leaving on the jewelry, and then put it in a closed sealed bag or packaging box to isolate the air and prevent the silver jewelry from yellowing and blackening.
If you wear it close to your body on weekdays, the oiliness of your body will also have the effect of using silver oil to maintain it, and it will have a warm and natural luster.
Step 2 restore bright colors
Silver ornaments will turn black due to air oxidation, contact with hot springs or strong acid solutions. Under the long-term wear and tear, the silver ornaments containing K gold will still be slowly exposed to the air. You can use a silver cloth to wipe the shiny, carved or irregular surface of silver jewelry, and you can gently brush it with a soft toothbrush with a little tooth powder or baking soda powder, which is natural and cheap. After brushing, let the foam adhere to the silver jewelry for about one minute, then rinse it with clear water and dry it with a soft cloth. You will find that your beloved silver jewelry has regained its bright color.
3. Don't use silver washing water
Try not to wash silver ornaments with silver washing water, because it will corrode the surface of pure silver. Although the brightness will be restored soon, it will turn yellow and black soon. And every time the silver washing water is used, it will corrode the silver ornaments again. For beloved silver ornaments, pay attention to the use of silver cloth.
Question 8: When the silver necklace is black, what can I use to wash the white silver ornaments? How to maintain it?
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. It is difficult to rub the silver ornaments white after many times of 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 is generally divided into electrogold and platinum; The way to identify electroplating is that its surface luster is brighter than pure silver, like a mirror, and its reflection effect is good. & gt
Question 9: Can real silver be washed with toothpaste? The essential answer is the maintenance method of sterling silver jewelry.
1. The best way to maintain silver ornaments is to wear them every day, because human body oil will make silver emit a warm and natural luster (there are exceptions, of course, some people's sweat itself contains ingredients that make silver black). When you don't wear it at ordinary times, you should put it away, and it is best to pack it in a closed bag to prevent the surface of silver ornaments from being oxidized and blackened by air.
2. Daily cleaning method: squeeze a little toothpaste on the silver jewelry, add some water, rub it with a soft cloth until white foam appears, or gently brush it with a toothbrush until it is satisfactory, and then rinse it with clear water to restore brightness. This method will not affect the quality of silver itself.
3. When wearing silver jewelry, don't wear other metal jewelry at the same time to avoid collision, deformation or wear.
Keep the silver ornaments dry, don't take them swimming, and don't go near hot springs or seawater.
5. When wearing, wipe the silver surface with a soft cloth every day to keep it shiny, preferably with a special silver cloth. Silver wipes contain silver maintenance ingredients and cannot be washed.
6. If the silver ornaments show signs of yellowing, clean the fine seams of the ornaments with a small jewelry brush, then drop a drop of silver emulsion on the paper towel to wipe off the black oxide on the surface of the silver ornaments, and then use a silver cloth to restore the original silvery white and brightness of the ornaments.
7. It is suggested that if the silver cloth can restore about 80% silver, it is not necessary 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.
8. When using silver cloth, first identify whether there is electroplating:
* Electroplated silver jewelry-inner layer of pure silver, surface electroplating. Electroplating is generally divided into electrogold and platinum. The way to distinguish electroplating is that its surface luster is brighter than pure silver, like a mirror, which has good reflective effect and is not easy to be oxidized. The simple way to deal with electroplated silver ornaments is as follows: you can go to the drugstore to buy a pack of alum, add water to boil the silver ornaments you wear at the ratio of (water 10: alum 1), take out the silver ornaments, put them in cold water, wash them with a soft brush (such as a toothbrush), dip them in toothpaste or laundry detergent, and blow dry them with a hair dryer before using them.
* Electroless silver jewelry-easy to lose luster due to vulcanization. Sulfur dioxide in the air reacts with silver to form a layer of silver sulfide on silver ornaments, which is the same as the apple will slowly turn black after being cut. ).
