What are the precautions for using gold-plated watches?
The gold-plated layer on gold-plated watches is mostly 14K gold. In addition to 58.5% pure gold, this gold also contains a certain amount of silver. After the silver reacts with some volatile industrial waste gas in the air. A black silver sulfide film will be produced on the surface. As a result, the gold-plated watch loses its golden luster. Therefore, wear gold-plated watches to avoid exposure to chemicals and exhaust gas, such as coal gas, liquefied petroleum gas, and sulfur soap. And always keep the gold-plated watch dry and clean. It is best to wipe with a flannel once a week. In addition, the chloride in sweat is very corrosive to gold-plated watches. Wipe clean gold-plated watches in time when they are stained with sweat. In order to avoid sweat erosion, the watch loses its original luster.
The yellow coating of a yellow-plated watch is a metal film composed of copper, zinc, and aluminum alloy. If the maintenance is not good, it is easy to fade and lose gloss. Before wearing a yellow-plated watch, wipe the case with a clean soft cloth and apply a layer of colorless nail polish evenly. Wear it after it dries, and then apply it every 1 to 2 months. After such treatment, not only can the color of the yellow-plated watch be maintained, it will not be worn out. It can also increase its surface brightness. At the same time, it can prevent sweat and moisture from entering the watch in the hot summer.
