Maintenance methods of Qianfa gold
1. When wearing gold and silver jewelry, do not contact with hard objects or pull hard. Due to the low hardness of gold and silver, it is easy to be scratched or pulled off when contacting with hard objects, which will damage the decoration of jewelry.
2. Wear jewelry where there is chemical pollution. At the same time, try to avoid contact with perfume, head oil, dew and other cosmetics. Once in contact, it is easy to make the surface of jewelry corrode and appear spots or discoloration. In order to maintain the luster of gold jewelry, you can often add a small amount of detergent in warm water, put the jewelry into a soft brush and gently brush it, then wash it with water, and then wipe it with a soft cloth and dry it.
3. When you take off the jewelry, you must clean it first and then dry it in the air, and put it in a place that the children can't touch. Because the children eat the jewelry by mistake, the jewelry will react in the stomach and bring harm to the children, so place it carefully.
