Maintenance method of gold

Although gold exists in the form of simple substance in nature, it will lose its original golden luster and magnificent charm if it is not carefully maintained. For example, the detergent you will come into contact with in daily housework will lead to the discoloration of gold, so it is best to take off the gold jewelry on your hands before doing housework, and don't use detergent and other cleaning agents to clean the gold jewelry.

In addition, we should try to avoid direct contact between gold jewelry and cosmetics such as perfume. In addition, it is best to take it off when going swimming or soaking in hot springs, because the pool water is also treated with chlorine, which may make gold jewelry dull.

In addition to easy discoloration, gold is also easy to deform! Gold is a soft precious metal, which is easily deformed. Therefore, wear gold jewelry to avoid collision and pulling. If gold jewelry is not worn for a long time, it should be wrapped in jewelry flannel and stored in a jewelry box.
