Gold jewelry is not very delicate, but without careful maintenance, it will lose its original luster and charm. In general, the following points are to be careful: 1. The chemicals of the detergent will change the color of the gold, so you should take off the gold jewelry before cleaning. 2. Avoid direct contact with high-volatility substances such as perfumes and hair gels, otherwise it will easily lead to fading of gold ornaments. 3. Remove the gold ornaments when swimming, so as to avoid chemical changes on the surface after encountering sea water or pool water. 4. When storing, wrap it in a velvet cloth and put it in the jewelry box to avoid mutual friction and damage. 5. Gold is soft and easy to deform, so don't pull necklaces and other accessories to avoid deformation. 6. Pure gold jewelry will produce a chemical reaction when it encounters mercury, and white spots appear. When cleaning under the alcohol lamp for a while, it can restore the original color. 7. The gold ornaments after wearing are often tarnished by stains and dust. At this time, just put the gold ornaments in a neutral detergent and soak them, then remove them and wipe them dry.
