Gold is chemically stable and is not afraid of water, so it can be dipped in water.

Just be careful not to touch cosmetics when putting on makeup every day. Gold turns white when it touches mercury in cosmetics. In this case, you can go to the jewelry store and burn it with a musket. Be careful not to wear it with platinum when wearing it normally, otherwise it will wear gold.

Usually touching some clear water has no effect on gold. Pure gold jewelry should avoid direct contact with cosmetics such as perfume and hair gel. When encountering cosmetics containing mercury and lead, chemical reactions will occur, which will easily lead to white spots on the surface of gold ornaments. At this time, as long as you bake under the alcohol lamp for a while, you can restore the original color. If it can't be solved, you can take it to a gold and silver jewelry store for professional jewelry care.
