News Guide: Wang visited several banks in Changchun City and failed to exchange successfully. On May 25, 2017, he came to Changchun People's Square branch of industrial and Commercial Bank of China for help. The money has gone bad and moldy, and it's covered with black hair and a pungent smell, which makes the bank staff unable to identify and count.
Liu Tiefeng is an old employee with more than 30 years' working experience. He has special experience in the counting and identification of coins. He rinsed the damaged RMB with tap water and then twice with 100 degree boiled water, and the moldy black hair on the surface of 160000 RMB was much less.
As the only currency circulating in our country, Grandpa Mao estimated that everyone loves RMB. Recently, it has been revealed that a man left 160000 yuan in his garage, and all of them became moldy and hairy. Is 160000 yuan going to float in the water? Then how should the RMB be preserved? What about the long hair?
How to keep the RMB?
RMB is mainly preserved against mould, fold, moth and fade.
The first is to prevent 'mildew'. The key to prevent mildew is moisture-proof, especially in the South and coastal areas. The focus of dampproof is the temperature and humidity of the notes. The best indoor temperature for banknotes is 18 to 20 degrees, and the humidity (relative humidity) is 50 to 60 degrees. Try not to deal with the collection in the high temperature and humid environment in summer. Generally speaking, the old paper money is more moldy than the new one. Once moldy, it can be gently wiped with soft paper or cloth. For paper money with serious mildew, it can be soaked in fresh milk, soaked in a small amount of salt for one hour, then fished out, rinsed with water, and dried with absorbent paper. When it is slightly damp, the paper money can be placed flat and clamped in the white book, and pressed with heavy objects to make it flat. Related article link: http://www.4hw.com.cn/life/licai.html
The second is to prevent 'folding'. New paper money should not be touched or twisted by hand. Because of oil and sweat on hands, it is easy to pollute coins. When watching the pictures, you need to use a camera. It's better to put paper money into the collection book. For paper money with a slight soft fold, put it flat in the book, press on the weight, and it will be flat in a few days. The paper money with obvious hard fold is generally dirty. It can be washed with water and dried. Paper money printed on tissue paper should not be washed with water, because it is easy to damage the printing surface and make it fuzzy. For uneven paper money, avoid ironing it with an electric iron, because it is easy to damage paper.
The third is to prevent 'moth'. To prevent moth is to keep the banknotes dry and ventilated in the day. For long-term banknotes, they should be read regularly every year. One is to play a role in ventilation; the other is to check whether there is any change in the collection. Never stack paper money with newspapers, books and other sundries. Moth eaten paper money should be mounted.
The fourth is to prevent 'fading'. The key to prevent the fading of banknotes is to avoid the exposure of banknotes in the sun. After a long period of preservation, banknotes will fade in varying degrees, which is directly related to the quality of banknotes and ink. Paper money should not be washed with alkaline or acid liquid, otherwise it will fade easily. Generally, paper money should not be placed in glass paper bags, which is also easy to fade. Once the paper money fades, it cannot be made up.
