I took 2 bills soaked them under the faucet, pat dried them on a towel, they were still pretty wet. I tried putting them into a AE2631D5 validator, the first was rejected, after about a dozen tries with the second bill it took it, it never would take the first bill. I then hooked up a AE2412U3 validator and tired inserting the damp bills, they both had started to dry out, after a number of attempts the AE2412 took both bills, but by that time they had dried out some more, but you could still feel the wetness on the bills. I don’t think there’s any validator that will take wet bill with any kind of regularity.
