Because gold is relatively stable as a metal material, chemical reagents such as lead and mercury contained in shower gel will react with gold, resulting in discoloration and whitening of gold. Shower gel contains acid and alkali substances, which will have an impact on gold and accessories on it.

Take off the jewelry set with precious stones when taking a bath. Soap for bathing is alkaline and will corrode some jewelry. Gem jewelry has strong corrosion resistance, and once it changes color, it can be solved by fire treatment.

Store the gold necklace in a dry place, or wrap it in flannel and put it in a jewelry box to avoid mutual friction and damage.

If it becomes discolored or black, you can go to a gold shop like Zhongmao Jewelry to clean it. In fact, don't wear it with you when you make up. Cosmetics contain chemicals, which will destroy the physical form of gold, so try to take off the gold necklace when making up.
