My client tried this method to keep silver jewelry from turning black for up to one year.
Question 5: How to clean and maintain silver ornaments?
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.

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 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). Electroless silver jewelry is easy to lose its luster due to vulcanization. Sulfur dioxide in the air reacts with silver to form a layer of silver sulfide; & gt
Question 6: How to clean the silver necklace by yourself? A, silver jewelry cleaning method:
Wipe the surface of silver ornaments with professional silver wiping cloth (except platinum plating process).
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 with alkaline water (such as soapy water); Finally, rinse with clean water.
Use toothpaste (try to choose the shape of green and transparent rice grains with fine particles to avoid scratching the surface of silver jewelry), apply the toothpaste directly on the silver jewelry, and 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;
Second, special instructions
If it is a stone inlay process, it is recommended to use a silver cloth to avoid washing with water and prevent the stone from falling off. 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.
Third, the maintenance method of silver jewelry
When not in use, it can be sealed and stored in a small plastic bag to isolate the air and reduce the chance of oxidation, so as to keep the ornaments fresh;
Alloy ornaments such as silver ornaments should be as far away from water and liquid as possible. When washing hot springs, you should take off your silver jewelry and wear it when bathing or swimming, but you should avoid touching sulfur soap, hair dye, perm agent and other items that are easy to damage the surface luster of silver jewelry.
Pay special attention to silver ornaments inlaid with stones, and try not to get wet, because there will be gaps in the mosaic joint, and the stones will fall off easily when they meet Sichuan.
For smooth ornaments, you can generally wipe them with delicate paper towels or soft cloth, and gently wipe them back and forth in the same direction to avoid too many scratches. The best effect is to use a professional silver wiping cloth.
Bright silver ornaments can be washed with silver. After cleaning, please rinse with plenty of water, and finally rub with a little alkaline water (such as soapy water or washing powder water) for a while, then rinse with water and dry with a soft cloth. Finally, the reason why washing powder is used again is to neutralize the weak acidity of silver washing water, so as to really play the role of silver washing water.
The silver ornaments of the old craft can be polished with silver cloth or toothpaste to restore their brightness. Remember not to use silver washing water to clean, otherwise it will destroy the old process.
Clean accessories correctly and wear them in the right way; When wearing a bracelet, you should wear it from the narrow side of your wrist and then rotate it around your wrist to the normal position. Don't break it hard, or the stones on the surface of the bracelet may fall or the bracelet itself will be deformed.
Question 7: How to clean silver jewelry teaches you a good method. CCTV Science and Education Channel taught me. I tried very well. Pour carbonated drinks into the cup and soak the silver jewelry in the cup for half an hour to ensure that the silver jewelry is brand-new and does not damage the silver jewelry. Simple and practical.
Question 8: How to clean the silver necklace toothpaste? Is it really effective? I washed it the day before yesterday. Gently rub the necklace with toothpaste by hand. Very useful. It is shiny after washing. A professional teacher told me.
You can put it in water. You can use an unused toothbrush. Just brush some toothpaste on the necklace. It doesn't matter. It won't be damaged. It will only get brighter and brighter.
Question 9: How to clean the silver ornaments at home? 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 of electroplating silver ornaments is as follows:
1. Go to the nearby Chinese medicine store or drugstore to buy a pack of alum first;
2. Boil the silver jewelry you wear with water in a certain proportion (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, as bright as new.
The chemical properties of silver are also relatively stable, and its corrosion resistance is also 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 combine to form a black silver sulfide film on the surface of silver jewelry, which begins to show as some tiny spots, and then spreads into pieces to form what we usually call silver scales or silver molds, which turn black and seriously affect the surface color of silver jewelry. When the silver jewelry has become seriously black, the following methods can be adopted:
(1): Soak in the solution of sodium bicarbonate (commonly known as baking soda), add a few pieces of broken aluminum under the first decoration, and heat them together to remove black spots and restore their true colors. The reason is that 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 some important decisions:
(l) New silver jewelry
For the newly bought silver jewelry, you can apply a thin layer of colorless or light nail polish on the surface, which has high transparency and is beneficial to increase its luster and delay 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 changes in 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 ornaments with spots
For silver ornaments with spots after being wet, you can wipe them off with warm vinegar and soft cloth, and then wash them 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 pure silver, with a ratio of 7.5% alloy and 92...>:& gt
Question 10: What should I do if the silver necklace is dirty? What can I use to wash it? There is a kind of silver cloth on the Internet, and it is also sold in jewelry stores. It is very cheap. Let's buy one with 2 yuan money.
Or if you have toothpaste at home, use a soft toothbrush and brush it slowly.
