Wet PS2 3V boards-

Hopefully, it was fresh water, & hopefully you don't have a lot of minerals in the water.  If you have compressed air, I would blow air gently through it with a blow gun, gently enough not to move parts.  If you don't, I would leave it right in front of a small fan in a warm (room temp) place.

If you have a lot of minerals in the water, I'd consider rising it first in distilled water, which you can get at many grocery stores.

First and foremost, don't power it up until it's cleaned and thoroughly dried!  Normally, water won't hurt a board, I've washed tons of PC boards with no issues.

Rice will work, and as stated keep it powered off until  thoroughly dried.  No rush on this.  Also make sure battery is unplugged. After dried, I would brush it off with a toothbrush incase any mineral deposits or other conducting material stayed on the board.   G

Thanks everybody, I blew the boards off with my airbrush compressor and stuck them in rice. Fortunately since they were on my work table awaiting installation the battery was disconnected and they haven't seen any powered. I'll let them soak in rice about a week before I install.

Thanks for all your help,

Scott

I wonder what rice will do with regard to areas of the board that do not come into contact with the grains, which are probably larger than the gaps between components. 

 I had this happen when my washing machine overflowed. I just left the shell open for a week and made sure everything was dry before testing. There was no damage.

Rice absorbs moisture.  In order for this to work, you dump it into a bunch of rice ina sealed container, and it will suck the moisture out.  You need to leave it for some time, at least a few days.  However, I'd first use compressed air to blow as much moisture out from under any components.

Another effective remedy is dunking it in an alcohol bath and then drying it.  Alcohol combines with water and then you can quickly dry the board.  After that, a few hours in a warm oven at 125-150F will finish the process.

GRJ, are you sure that the boards can take temperatures of 150F?

I'm 100% sure, that's how PCB manufacturing houses dry them.  150F is 65C, well within the storage temperature for any component that I'm aware of on these boards.

I always douse them with alcohol and blow them dry, then let them sit for a day.

That works just fine Chuck, the alcohol absorbs the water, then blowing it out gets most of it.  The rest should dry in a day, I'm just impatient so I use the oven.

I keep mine dry...bada boom!  Surprised so many wet boards.  G

Sounds like your baking a Christmas cake; plenty of alcohol and bake until everything is just right

It's tasty as well.
