I wouldn't take the chance ... the one thing we all should have learned when we were kids is that water + electricity = a bad time. You never know what wires fried or what is now corroded and in time will eventually start causing malfunctions!
I would take extra caution if you decide to use it and like brenden said ... wash it down with some FW
and then let it dry for a LONG time!! Even then after doing that you may want to take it apart and check out all your connections and wires to make sure nothing is bad!
