the worse thing you can do for any device after getting it wet is keeping it on and/or turning it on. having juice flowing is what causes the actual damage in the form of a short somewhere.

anytime you get a device wet, IMMEDIATELY do as much of the following that applies: unplug it, turn it off, and remove the battery.

after that, you just want to allow the device to dry off. you do a bunch of things to help speed up the process like remove covers and such. you want it to be completely dry before you try turning it back on and testing for any damage.
