I was the one with the G9 that was flooded and saved with a fresh water rinse. Just as an update, the flash recently stopped working, so it is out for repair. Hopefully, it is something simple. Couple of things.....
1. I completely flooded the camera with freshwater as soon as it was available to me.
2. I actually placed the camera in a gas oven (with pilot flame) for around 13 hours.
I think the dry heat created by the pilot flame is what took all the moisture from the camera. Everything works fine except the flash of course. Oh, and the internal battery is apparently dead now since it needs the date every time I boot it. No biggie as a quick press of the shutter button passes that prompt.
Good luck with your revival.
