Wow.If you put your money into a dishwasher or a washing machine then your money is going to surely glow under a UV light. The powers/chemicals used are fluorescent. You know what normal paper looks like under a UV light? Like a lamp.You know what paper money looks like under a UV light? The exact same apart from the designed bits which are supposed to fluoresce anyway. This is the No.1 method banks and shops detect counterfeit bills. Because getting the right kind of paper to make counterfeit notes is non-trivial a task unless you own a paper mill. A bank will instantly spot a stack of notes treated with washing detergent and report it to a LEO because they'll assume you're a counterfeiter, how do you imagine that going down? ("oh, lol, no, you're a drug dealer lol, our honest mistake, sorry about the trouble Sir")Do not use washing detergent on your bills unless you want the Secret Service monitoring you. No kidding, due to some freak of united states bureaucracy, the same guys who protect POTUS also are the dudes who are supposed to track down counterfeiters. Google it if you don't believe me.--Use rubbing alcohol. You don't need to be rough, a simple hand wipe accomplishes much. If you get a powerful UV light (wear protective eyewear with yellow lenses), you should be able to detect any fingerprints before/after, and there is the benefit that strong UV light will practically murder any organic stuff like DNA, which is why doctors in hospitals wash their hands under specially designed UV light stands (it's not blue to look cool).Use a hair dryer to dry the bills individually. Alcohol evaporates very fast. There won't be any remaining when it reaches bank HQ. You shouldn't wash your money, but you should dry it, lol! :DLastly; use gloves. It's a basic requirement, whether or not you think the prints are recoverable. It's cheap. It's effective. It's guaranteed to work. srslyyouguise.jpg
