Close any windows and try to minimize air circulation so the bills aren’t getting blown away. Divide the bills. In order to get each bill as dry as possible, you need to separate each one and arrange them next to each other in your sunny location. Leave the bills out for a few hours. The time varies based on how sunny it is and how soaked your bills are. In most cases, it only takes 2-4 hours for the sun’s warmth to cause the water to evaporate from the monies, leaving them crisp and dry.
More than 50 percent of the bill must be able to be identifiable as U. S. currency by the BEP. If your wet bills have been severely ripped, the BEP may still accept them if you can provide enough supporting evidence that the missing portions have been destroyed. For those in the United Kingdom, The Bank of England offers a similar service for replacing damaged currency.
For wet bills that were rolled, never attempt to unroll or straighten them out. For bills that were straight when water damaged, don’t roll them up or add any adhesive if the bills were ripped. Wet currency that’s especially frail should be wrapped in cotton or plastic in order to preserve it as much as possible.
