Take off the inlaid pearls and soak them in boiling water. After a few minutes, I shook it with pliers and came down.

Pearl maintenance: 1. Anti-acid and anti-corrosion: For the brightness and luster of pearls, try to keep pearls away from chemicals such as acid, alkali, soap and perfume, so wear pearl ornaments after makeup. 2. Stay away from the kitchen: there are tiny pores on the surface of the pearl, and the kitchen fumes will penetrate into the pearl and make it yellow. 3. Avoid sun exposure: The pearl itself contains some water. When wearing or maintaining, make sure that the pearl is in a cool place, not in a dry place, otherwise it will dehydrate and become dull.
