The best option with any "damp" electronics is to leave it to dry out as slowly as possible and DO NOT keep switching it on as any "damp" components will possibly break down + fail altogether.Leave it in the corner of a warm room for a few days...the longer the better.
I`ve met this situation several times and so far the above has worked ( even for an IPOD that went swimming in the sea! Good Luck
