What to do if the ear needles are black

time：2021-11-16 source：sznbone Views：

The blackening of the ear acupuncture has a very large relationship with the oxidation reaction. The blackening not only makes the ear needles look dirty and old, but also affects their appearance. Oxidation is inevitable, but jewelry factories have many small tricks to solve the problem of blackening of ear needles.

The oxidation phenomenon produced by ear acupuncture is unavoidable, as long as it is jewelry, it will happen. If you want the darkened ear acupuncture to become bright again, you can use a silver rub to clean the ear acupuncture. Put an appropriate amount of silver rubbing cream on the black areas of the ear needles, use a handkerchief or paper towel to gently rub the black areas repeatedly, and then completely dry them to make the ear needles white again.
