Gold maintenance has a knack.
Gold is soft and easy to deform, so don't pull necklaces and other accessories to avoid deformation. When you don't wear it for a long time, you should wrap it in flannel and put it in a jewelry box to avoid rubbing against other jewelry.
Chemicals such as detergents and disinfectants will change the color of gold, so gold ornaments should be removed before cleaning and swimming to avoid chemical changes on the surface.
Pure gold jewelry should avoid direct contact with cosmetics such as perfume and hair gel. When it comes to cosmetics containing mercury and lead, it will have a chemical reaction, which will easily lead to white spots on the surface of gold jewelry. At this time, you can just bake for a while under the alcohol lamp.
After wearing, the gold ornaments often lose their luster due to stains and dust contamination. At this time, just put the gold ornaments in a neutral detergent and soak them in warm water, then take them out and dry them.
