How to deal with silver jewelry turning black?
Because of its exquisite and rich styles and low price, silver, as a more common type of precious metal, can meet the market demand of consumers and is deeply loved by consumers. Compared with gold, silver is hard and not easily damaged. But silver also has a shortcoming, that is, it tends to turn black and black for a long time, and it becomes very ugly. Usually it is troublesome to get the jewelry store to clean, and if you use silver washing water, it will corrode the silver surface. In fact, we can also clean silver jewelry at home. The tools we need are generally available at home, and the method is simple and will not damage the silver jewelry. Let’s take a look.
The reason why silver jewelry tends to turn black is that it easily reacts with sulfur or hydrogen sulfide in the air to produce black silver sulfide. Therefore, relative smuggling is to wash away the black silver sulfide on the surface. As long as you master the correct method, you can easily wash it off without harming the silver jewelry.
First, clean toothpaste. Cleaning with toothpaste is generally suitable for plain silver jewelry with a smooth and flat surface. Dip a small amount of toothpaste with a waste toothbrush, and repeatedly scrub the black hair until the surface of the silver jewelry is as clean as new. After scrubbing, rinse with clean water. Washing collars and non-flowered bracelets in this way is very effective, but if it is used to clean carved or carved silver jewelry, it is not recommended to use it because of its poor effect.
Method 2: Prepare a small bowl, and then cover the bottom of the bowl with a large tin foil, with the shiny side facing up, and then put the silver jewelry that needs to be cleaned, pour salt into it, and the salt must cover the jewelry.
Finally, pour in boiling water, stir with chopsticks, wait a few minutes, and you will find that the black and black hair of silver jewelry has disappeared. If there is no tin foil in the house, aluminum foil can be used instead. The tin material is aluminum, which together with salt provides an electrolyte environment mechanism. After heating with boiling water, a chemical reaction occurs, and the silver sulfide is reduced to the original element through the electrolyte environment. Therefore, our jewelry naturally becomes as bright as new. Using this method to clean silver jewelry will not harm silver jewelry. The method is simple and the materials are easy to find. But it should be noted that this method can not be used to clean silver jewelry inlaid with alloy jewelry, otherwise it will easily damage the jewelry, and the gain will not be worth the loss.
Method three: alcohol or ammonia. You can prepare a clean piece without alcohol or ammonia scrubbing, and react with black oxide. This method is relatively mild.
In addition to daily maintenance and cleaning, silver jewelry is also very important to wear. If used improperly, the oxidation rate of silver jewelry will increase. When we bathe and sleep, it is best to take off the silver jewelry and avoid contact with sulfur soap softeners, perming agents and other items. When you are not wearing silver jewelry, you must seal it with a plastic bag to prevent excessive air contact from causing oxidation.
