How to clean rusty old dollar bills

[@iradernotsei]

I see a problem with this method. While the acetic acid (vinegar) removes the stain, without "flushing" the bill with lots of water afterwards, there's going to be acetic acid remaining in the fibers. Over time, these fibers will "yellow" possibly leaving the bill in even worse shape. You might think of what is sold to archivists when they use paper for any documents or document storage - "ACID FREE" Paper. Putting vinegar directly on a bill and leaving it there is the exact opposite of what you want. A final step would be to either wash away the vinegar or entirely neutralize it (bleach? some hydroxide?), but be careful because you're introducing another chemical. N(OH)3 for example will weaken the H+ bonds in the paper and possibly make it more fragile. The safest approach would probably be to flush the bill with plenty of water and then dry under a heat gun set at low or wrap the bill and use an iron. Most Banknotes are printed on a cotton paper, so they don't get as wrinkly as regular tree-pulp papers, but you still want to avoid absorption of excess water into the fibers, particularly those along a bend or fold. I'd like to know if anyone has any comments to follow up because I'm new to this (Numismatics) and my comments here are more from the point of view of photo and document archival best practices.

Not all banknotes are made of the same material. Old Chinese or Yoguslavian banknotes will be negatively affected by using any kind of acids since they were made from bad stuff. Isn't there any other simple way to clean old and cancelled banknotes? Thanks in advance.

This is so dumb when it come to collectible bills. You NEVER clean bills or coins that are collectible.

Do you know I need to clean my dollar bills because the money changer in my country refused to accept stained dollar bills which is even dumber. I need to find a way to clean it in order to get them changed to another currency 😡 I'm just so pissed with the money changer and I cannot even change it in the bank because this service is no longer available in all banks!
