Speaking of colored gold, many people should like colored gold jewelry. This kind of jewelry is actually not uncommon. However, after wearing it for a long time, the colored gold will become not as bright as before. This is because it has lost its luster due to dust. Just clean it.

Clean with alcohol and soap, wipe with a soft cloth dipped in soapy water and hotel, do not use anything containing particles such as toothpaste to avoid scratching the surface, and it will be very bright after being scrubbed once a week. Soak in ammonia water, soak the 18K gold necklace in ammonia water overnight after it gets dirty, and the dirt can be washed away. Be careful not to set the concentration too high to avoid corrosion of the protective film. Bake with an alcohol lamp, there are often white spots on the appearance of the necklace, which is mainly caused by the use of some cosmetics containing mercury, which are stained on the surface. Mercury can melt when it encounters high temperature, and then gently wipe it with a soft cloth.

When cleaning the gold, you can use a special detergent to clean it. If there is dust on the gold, you can use a soft brush to gently brush off the dirt and gray on the surface. You should also pay attention to the maintenance of the gold. When cleaning the gold, you can use toothpaste, and then use a soft brush to gently brush it. After removing the dirt, you can wipe it dry. Generally, it is less exposed to water or washed with water, because water is not "friendly" to the gold. If you can't clean it yourself, send it to a special jewelry counter and let the staff of the counter help you clean it. Gold also needs maintenance. Generally speaking, the jewelry is sent to the after-sales service for about half a year to help clean it, or it will be electroplated. Because there is a layer of electroplating on the surface of the gold, because we sweat every day, and we also use cosmetics and skin care products, this electroplating layer will gradually age after contacting these things, so sending it back to the manufacturer for electroplating is undoubtedly a good way. When taking a bath, swimming, and soaking in hot springs at the seaside, you need to take off the gold, because water also has an impact on the electroplating layer. The water in the swimming pool is usually added with some disinfectants. When you go swimming at the beach, the water is full of salt, which also affects the electroplating layer. The hot spring water is very high in temperature, and some hot spring water also contains some minerals, which also have an impact on the electroplating layer.

What is the difference between soft gold and hard gold?

1. Different gold content

Soft gold and hard gold are both types of gold jewelry. There is no difference in quality between the two, but the main difference between them lies in the gold content. Hard gold is also called physical gold. The gold content in it is very low, and most of it is metal. Soft gold is high-purity gold, so its hardness is not high.

2. Different hardness

Hard gold is a type of gold jewelry made with a new technology. Its texture is relatively hard, so it is also called 99% hard gold. It is mixed with a lot of other metals, mainly copper alloys, so it is very hard. Soft gold has a high gold content and a soft texture, so it is not suitable for inlay.

3. Different uses

Due to the difference in craftsmanship between hard gold and soft gold, their uses are also different. Comparatively speaking, hard gold is much cheaper than soft gold, but hard gold can be used for various inlays, which can make gold jewelry more valuable, while soft gold is used to make various gold artworks and is more suitable for people to collect.
