Good save. My pager hit the toilet once too and I didn't get the battery out in time.. it only received half it's pages after that.
Unfortunately I can't clean my broken screen.
My cousin once poured a whole can of rootbeer into his laptop (that he was purchasing from me). It took 2 quarts of 99% isopropel alcohol to clean it out. Isopropel is wonderful for displacing water out of electronic devices and then evaporates itself, but you need to ask for the 99% at the Rx counter, not the 70% on the shelf.
