The gold-plated necklace, as its name implies, is a layer of gold, which looks more like gold, but it is easy to oxidize when exposed to air. How to clean the gold-plated necklace when it turns black? Are gold-plated necklaces harmful to the body?
How to clean the gold-plated necklace when it turns black
The gold-plated necklace can be cleaned with toothpaste or sent to the electroplating factory for cleaning.
1. Toothpaste is a good helper in removing black.
The blackening of gold-plated necklaces is due to oxidation. Toothpaste can remove oxides on the surface of gold-plated necklaces. You can scrub with toothpaste and then rinse with water. Toothpaste is rich in fine calcium carbonate particles, which can wipe off the oxides on the surface by friction. Find a toothbrush, dip a little toothpaste and rub it patiently for a while, then wash it off with water. It should be noted that after scrubbing with toothpaste, be sure to wash with clean water, preferably with pure water, not with the kind of chlorine disinfected tap water.

2. Send to electroplating factory for cleaning.
If you really can’t clean it up, you can also send it to the electroplating factory for cleaning. The electroplating factory polishes the surface of the product with a water wave polisher to remove the oxidation product, and then undergoes pickling treatment, so that the processed product can be placed in the electroplating tank After electroplating, the electroplated product is as shiny as the original. Wiping the gold-plated surface with other wiping cloths will erase the electroplated layer. When removing black, it will also remove the gold on the surface, and it will not restore the gold on the surface. Gold-plated necklaces turn black because the gold-plating has been oxidized. Gold-plating is divided into two types, one is gold-plated with homogeneous materials, and the other is gold-plated with heterogeneous materials.

The gold-plated necklace is not harmful to the body, but it has a relatively large impact on the environment, and will not affect the human skin. It is just that the production and processing of gold-plated silver is very harmful to the environment, but it is harmless to people. Gold and silver with high purity are less susceptible to allergies than other metals and are better for people than other alloys. The electroplating layer is a layer of precious metal that is plated on by the electroplating process, то есть, the bottom layer is also the base layer of other metals after it is peeled off, and it will not have much impact on the skin.

Gilding is a decorative craft and one of the commonly used words. At first it meant to plate a thin layer of gold on the surface of the utensil. Позже, it was also used as a metaphor for people to go to a certain environment to study or exercise just to gain a fame. Gold plating is divided into two categories, one is gold-plated with homogeneous materials, and the other is gold-plated with heterogeneous materials. Homogeneous gilding refers to gilding the surface of gold jewelry. Its meaning is to improve the brightness and color of jewelry. Gold-plating of heterogeneous materials refers to the gold-plating of the surface of non-gold materials, such as silver plating and copper plating. Its meaning is to replace the color of the plated material with the luster of gold, thereby enhancing the ornamental effect of jewelry.
