Gold is soft and easy to deform, so don't pull cheap necklaces and other accessories to avoid deformation. When not wearing for a long time, apply the velvet cloth and put it into the jewelry box to avoid rubbing damage with other jewelry.
Chemicals such as detergents and disinfectants will change the color of gold, so clean it and remove the gold name bracelet before swimming to avoid chemical changes in the surface.
Pure gold jewelry should avoid direct contact with perfumes, hair gels and other cosmetics. In the case of cosmetics containing mercury and lead, it will produce chemical reactions, which will easily lead to white spots on the surface of the gold ornaments. At this time, you can restore the original color by baking it under the alcohol lamp for a while. If you can't solve it, you can get a gold jewelry store for professional jewelry care.
After wearing, the gold ornaments often lose their luster due to the stains and dust. At this time, just put the gold ornaments in a neutral detergent and soak them in warm water and wash them, then remove them and dry them.
