Another handy way to recover after this sort of catastrophe: remove the 
battery (quickly, as others have said) and then put it in a bucket with 
_distilled_ water. Slosh it around a bit, pull it out, dump that water, 
and repeat.

Then dry it out with the 140F box. Compressed air can help get water out 
of the crevices, but go gently.

Pure, distilled H2O is non-conductive and is used to "aqueous" wash some 
electronics after soldering/reflow. Keeping a few gallons of distilled 
water around is useful for soldering sponges, irons, radiators, etc. too!
