like the LCDs were broken, so I told her it was a goner. Next day she
took it to the Verizon kiosk at the mall, to buy a new one. The guy
said "they're tough... try it" so she did, and it worked. The LCDs
were still useless, but that's because they were full of water; a
couple of hours in the sun dried them out. Now everything works,
including both LCDs and the camera. She's happy; I'm impressed.
I wonder if they have an immersion sensor. That would be easy, just an
unpopulated 0402 part, or even an unconnected pin on an IC if done
right. One could shut down most everything to minimize electrolytic
damage. An ideal component would be an 0402 gadget that went lo-z when
wet and took a long time to dry out, sort of a sponge with end caps,
connected into the power supply to shut down everything when the guts
were wet.
Is anything like that being done?

In Africa my pal dropped his rental cellphone--our link to
civilization--in the Indian Ocean. It started to smoke.
"Quick, take out the battery!," I said. He did.
A bit of corrosion near the battery terminals. Hmmm.
Rinsed it thoroughly in the cleanest fresh water we
could find, dried it out (took a couple days).
Good as new.
Salt water being the worst possible dunking.
General recipe is as you said - take the battery out and wash with
water. Ideally distilled. Then, if you have the luxury, dunk it in
denatured alcohol and then dry.
Alcohol would've made it dry faster, which would've been nice.
As it was I was glad just to find clean rinse water, and
fresh to boot!
The worst damage by far was electrolytic corrosion driven
by the battery. Salt water is surprisingly conductive.
Surprised me, anyhow.
Alcohol absorbs moisturer and leaves things wet. After alcohol treatment it
must remain warm enough
and should first be blowed out. My Weller hot air pistol works well.
I usually put the phone under a 100 watt lamp 1 foot away. I then
cycle it to make it breath. One phone was very difficult. I
took it apart several times. After a week or two it was OK.
I had to clean every little part. I also prefer ending in a lubricant
VCI like Bullfrog.
