It's not just the water. it's the other stuff that's already on the
board.
Flux residue, electrolyte leaking out of caps, glues used in the assembly
process. Whether or not the final inspector belched on it,
Whether the cat peed on or near it. I'm gonna go out on a limb and
suggest that water is never the problem. It's what is in the water
that causes the grief. Water just ionizes it and makes it mobile.

Good point, Mike. There may have been something on the cell phone board
that was not on my experimental board. I did however scrub the cell phone
board twice with Radio Shack Electronics Cleaner and I think that there is
still some effects left from the submersion. I only did the experiment
since I thought that some were suggesting that there was some corrosive
residue created by the material in the less than pure water, but they may in
fact have been referring to residue materials of the type that you have
suggested.
