I dropped my camera in saltwater (actually it slid in hanging around my neck -- I slipped on seaweed). I took it home and rinsed it out in tap water, dried it out in the oven and shipped it back to the mfg. They said it was a write-off and shipped it back. I started taking it apart, dripped some wd-40 in it and forced some rewind/shutter gears (not knowing exactly what they did). It started working again. I think I probably fucked up the lens mount alignment though, and the TTL metering was shot. I used it for the next 20 years, and took a lot of good pics with it. For some things (surviving salt water baths), electronics suck.
