Many good advices already. The key is to dry the boards out as quickly as possible and to not power them up until you know they are dry to prevent any shorts which would fry components. Leaving humidity/water in contact with components will lead eventually to oxidation so time is of the essence. If I only had a handful, I would immerse the PCBs in an IPA bath before letting them airdry but you may have too many to do that. Alternative is to use a hair dryer in low settings and dry them at 40-50C.

Hi! Thank you for the advice! With a number of people suggesting IPA, I was going that route, but was assuming I would be applying the IPA to the PCBs with a cloth. It sounds like you are suggesting immersing the whole PCB in IPA, is that right? I have only 6-7 that were fully submerged and have a ton of moisture on them now that I have started taking them apart. No problem to immerse them, but I have not done that before, want to double check I am understanding right before I put them all the way in instead of dabbing them with cloth.

Thanks!
