Gold plating is a decorative process and one of the commonly used words. Common gold plating includes silver gold plating and copper gold plating, which means that a thin layer of gold is plated on the surface of silver, copper and other metals, which is called "gold plating". By gilding silver ornaments or copper ornaments, bright and clear colors can be obtained, which is easier for people to like and accept.
According to national regulations, the gold plating layer of gold-plated jewelry should not be less than 0.5 micron, and one micron is only 0.00 1 mm, with GP or KP logo. Most gold-plated ornaments are gold, such as gold, light gold or rose gold. Because it is easy to wear and fade, wear gold-plated jewelry to avoid contact with acid and alkali.
How to repair the gold-plated discoloration at home?
1, nail polish
When the gold plating becomes discolored, first clean the gold plating, then evenly apply colorless nail polish on the discolored place, and then apply it when the nail polish is dry. Nail polish can increase the color of gold plating, so that it will not fade for a while.
2. Cleaning agent
Soak the faded gold plating in the washing liquid mixed with neutral detergent and warm water, and then take it out to dry. This situation is suitable for gold plating when stains change color, mainly for cleaning.
3. Re-gilding
If the gold plating fades badly, take the gold-plated object to a gold shop or a jewelry shop, and ask professionals to re-plate the faded gold-plated object with a layer of gold. After re-gilding, the gold-plated items have regained their original luster, just like new ones.
