Just a supplement to your point of water not always being fatal to electronics - I once found a PSP lying at the bottom of a lake. It was by a school, so I guess bullying had been involved. One thorough rinse later and it turned on. Battery and optical drive were shot of course, and the screen was seriously watermarked. But still.
I’ve sent many desktop keyboards through the dishwasher. Pop the keycaps off and put them in the flatware compartment first; allow 48 hours to dry before re-assembling and plugging in after. Even the cord comes out looking good as new.
