Hello method one:

Brush it clean and then put it in the sun to dry, or you can also brush it directly with toothpaste, but it will also work better with baking soda!

Method 2: Soak the copper bracelet directly in vinegar, and take it out and clean it with water for about two to three hours.

If it is left for too long, it is very easy to cause the copper bracelet to be corroded, which will become more black, so that the gain outweighs the loss.

The blackening of the copper bracelet is the oxidation of copper. Copper also melts when it encounters air. So the copper bracelet turned black.

Of course, it is oxidation, and it will also oxidize in contact with air.

If it is washed with water and sweat, it will grow patina, and if it is washed with water stained with chemical agents, it will turn black, such as with disinfectant and alcohol. These are all normal phenomena, as long as it is copper, take a toothbrush dipped in some toothpaste and brush it will return to normal.

I don't know. May you be in a brilliant mood and live a comfortable and worry-free life!
