Why does gold turn red when it is left for a long time?
Because gold royalty technology does not contain 100% gold in real life, it may be mixed with other impurities. If the surface is placed in the Korean Wave environment for a long time, it will produce red spots, and gold may also produce red spots when it meets acid, which is caused by the oxidation of internal impurities and the oxide layer on the jewelry surface.
There is another situation, because in the process of gold processing, the tool used to clamp gold is usually an upright post. These red spots are red because of the iron filings left on gold by tools in the later stage and the rust formed by oxygen in the air. These situations generally occur on gold bars or coins, and gold ornaments generally do not turn red.
How to deal with the redness of gold after it has been put for a long time?
1. Toothpaste cleaning
In some families, gold jewelry has lost its luster. In fact, this problem is not big. It's just dirty. It hasn't been cleaned yet. Therefore, only cleaning can restore the original state.
Homemade detergent
If you don't want to clean with toothpaste, you can mix salt and vinegar to make a cleaner. This self-made cleaner will be mild and less harmful to gold ornaments. Specifically, you can wet the jewelry cloth with this cleaner, and then gently wipe the gold jewelry to restore the luster of the gold jewelry. This method is relatively simple and does not need much time.
How to maintain gold is the best?
Before cleaning gold jewelry, we can dilute warm water with soapy water or neutral detergent at home, soak gold jewelry 10-20 minutes, and then scrub it with cotton swab or towel. If there is a gap, please use a soft toothbrush. Don't touch a small amount of toothpaste, brush your teeth gently. Be sure not to use granular toothpaste to avoid wearing gold ornaments. Finally, put it into a container filled with clear water for cleaning, and then dry the cloth to absorb water.
In addition to routine cleaning, we should also pay attention to daily wear, try to avoid pulling, take it out as much as possible when bathing, swimming or sleeping, and put it in a box with gold ornaments alone. Do not wear it with other materials.
