Paper money is not as durable as coins. Besides, handling it poses a health hazard. That’s because as paper money circulates amongst different users, it picks up residue, germs, and other poisonous substances that are harmful to your health. That is why the notes’ manufacturers use a waxy coating substance that changes color as the notes get dirty. That enables them to know when the note has accumulated enough dirt.
The central bank has laws that govern the circulation of the notes. According to the regulations, the bank pulls out different notes circulating for a specified period. Then, they clean and treat them before releasing them back to the market. The process of washing and treating only notes saves the state millions of dollars compared to printing new ones.
When cleaning the notes, cleaners use cleaning detergents. The detergents are the same as the other cleaners in the industrial cleaning industries use. They are strong enough to get rid of the germs and other harmful substances in the notes. After the process, all the notes look as good as new, with all the security features intact. So, there is no need for printing new notes when cleaning them will get rid of the harmful substances without damaging them.
How Central Bank cleans dirty notes
The government sets aside a substantial amount of money from the budget to clean dirty notes. The money enables the central bank to acquire different washing materials and equipment that will not damage the notes during the washing process. When washing the notes, they have to be careful not to damage the security features. So, they avoid using hot water and certain detergents that are harmful to the notes.
Therefore, the people who wash money ensure that their techniques do not threaten the notes’ longevity. Initially, money cleaners used carbon dioxide and pasteurized heat. But, they have since changed, and they presently use safe substances that clean the notes appropriately without damaging any of their features.
Importance of cleaning money
The process of printing new notes after several years is expensive. Besides, disposing of the old dirty notes is challenging because the central bank has to dispose of the notes in a secure way that does not pollute the environment. Apart from that, there is the challenge of transporting the old notes. If robbers realize that the central bank is transporting the old notes, they could craft a plan to steal them.
After the circulation of paper notes for several years, they turn brown due to different human skin substances. That makes it hard for machines that handle the money to recognize them. When the central bank withdraws the notes, they take time to examine them. That enables them to determine the ones they can wash and the ones they will destroy if washing them will damage the notes’ unique features. After washing the notes, the money is safe, and the machines can easily recognize different notes by their denomination.
Compared to printing new notes, cleaning them saves the government millions of dollars. However, the central bank must ensure that they use the right techniques and materials that will not damage the notes’ security features.
