Why did the silver earrings turn black?

Everyone knows that silver products have many benefits to the body, so many girls like to wear silver earrings, especially those who are more prone to allergies, who are very suitable for wearing silver earrings. When silver earrings are worn for a period of time, they will turn black. This is a normal phenomenon, mainly caused by the oxidation of the silver material. There are many ways to clean silver earrings after they turn black.

Reasons why the silver ring turns black

First of all, silver will oxidize and turn black when it comes into contact with air. There is also oxygen in water, so silver may oxidize and turn black regardless of whether it is exposed to water or not.

Secondly, silver jewelry turns black because silver reacts chemically with sulfur in the air to form black silver sulfide. When wearing silver earrings, the human body's sweat contains sulfur, ammonia, etc., and the air also contains substances such as hydrogen sulfide and nitric oxide, which will cause the surface of the silver jewelry to be oxidized, and then discolored and lose its luster. The blackening of the tremella ear studs is also related to the acidity and alkalinity of human sweat. If the sweat is acidic, the tremella ear studs will turn black faster.

Although the appearance of the silver earrings does not change much after they turn black, you will always feel uncomfortable every time you wear them, so you need to clean them quickly.

What to do if your silver earrings turn black

1. Toothpaste cleaning method:

Toothpaste is a great stain remover. Just squeeze a little toothpaste on the white earrings, wipe them with a small towel until small bubbles appear or brush them lightly with a toothbrush, rinse with clean water and wipe dry.

2. Friction of pure cotton fabric:

You can wipe the surface of the silver earrings with a rough cloth, but the cloth should not be too hard. For example, denim is a good choice.

3. Lipstick wipe:

Apply lipstick on the cloth and wipe the blackened surface of the silver earrings with the cloth.

4. Silver washing water cleaning:

If it is really impossible to clean it, you can use silver cleaning water to scrub it and then wipe it dry with cotton cloth after washing.

5. Silver jewelry store cleaning:

If you take them to a jewelry store to have them cleaned and polished, the silver earrings will regain their luster, but this will cost a certain amount of money.

General silver jewelry cleaning method:

When silver oxidizes, you can use silver cleaning water or silver polishing cloth to polish the silver jewelry. However, silver cleaning water is very lethal, so try to just wipe it with a silver-polishing cloth; if you use silver cleaning water to polish it, rinse it immediately and rub it gently, clean the chemicals on the surface, and blow it dry with a hair dryer, otherwise the oxygen in the water will accelerate the oxidation of the silver.
