Matters needing attention in gold jewelry maintenance:
Avoid contact between gold jewelry and mercury-containing substances or industrial waste gas, so as to avoid corrosion and discoloration of jewelry, resulting in losses.
When taking a bath or doing housework, it is recommended to take off the gold jewelry you wear to avoid contact with chemicals such as soap, bleach or detergent and corrosion.
Gold ornaments should avoid rubbing against hard objects, and also avoid hitting or falling. If you don't wear it at ordinary times, it is recommended to put it in a separate jewelry box.
For gold ornaments that are often worn, always check for looseness and wear. If the above situation occurs, it is recommended to send it to a regular gold shop for professional maintenance in time.
