It isn't quite true that pure water won't cause corrosion.
It is actually slightly acidic. I recall reading about
a large cosmic ray detector ( large pond of water ) where
the water was ultra pure. The metal pieces would often
just disolve.

My gut feeling was water+electronics = bad... It
seems pretty unfounded
looking all the advice from this list.
water + electronics + electricity = bad. This is because it causes short
circuits that can fry components. As long as its completely dry, there's no
water to cause the shorts. The other problem is corrosion. Pure water
wouldn't do that, but all the other crud floating around in water is left on
the component when water dries, encouraging corrosion. This is why you wash
it off with a solvent (that doesn't leave deposits of its own).
