    I work for a security company and we protect money cassettes by staining bank notes with ink if an alarm goes off. The bank notes consist of polymer. I think it would be cheaper to damage the bank notes with chemicals. So far I experimented with acetone, ether, chloride and hydrogen. The chemical component should be human friendly, so agressive corrosive acid is not an option. Does anyone have an idea how to bleach bank notes or change their color? Effective processes will be rewarded with 50

    What polymer are they composed of? there are various household items that may cause a change, even simple vinegar.

    Your bank notes are made of plastic? I thought they were made of paper. Ink seems like the best idea. But ink is a chemical. What sort of effect are you looking for?

    Thanks for the replies. The bank notes are made of some kind of polymer but the manufacterer can't tell what sort to prevent counterfeiting. Bleaching or colouring processes would be ideal. As long as the used chemicals don't cause burn wounds - how strange it might seem, robbers can actually sue us- everything goes. In the past, pyrotechnic techniques were also used but are less used now due to some accidents and explosions. It's a quite fascinating job once you are into it. This might be a bit extreme but I was thinking towards some kind of mild version of thermite, to cause heat and burn the notes without any big flames.
