Distilled water is used to wash the tap water water off boards which
washed off the water soluble flux used because it doesn't leave mineral
water spots behind when it evaporates.
It doesn't stay on there long enough to corrode anything.
You most certainly don't want salt crystals left behind on the PCB
because salt absorbs water out of the air, is conductive and
will electrolytically make hash out of the circuits when run, very
quickly. [Not to mention a lot of cross talk between high impedence chip
and transistor inputs ]
The toxic flux removers like carbon tetrachloride are for petroleum based
salamoniac rosin core fluxes which haven't been used since the advent of
the flow solder machine...except for the hand assembled parts that won't
stand the heat.
Plain old Coleman stove fuel works pretty good [Naptha] or a shot of carb
cleaner.
Now, with robot assembled surface mount tech, the flux only goes where
it's needed and the boards aren't washed as there is no excess to wash.
I've manufactured many thousands of PCBs since 1970 in all the stages and
still spend many hours a day populating them...old through hole tech and
completing new robotic surface mount.
The makers of stainless pots say DON'T leave salt water in a pot as that
will pit the surface.
Distilled water only sucks up soluble minerals and metallic nickel ain't
one of them.

Pure distilled water is fairly corrosive to metals. A friend who used
to work in process engineering at one of the biggest circuit board
assembly companies told me that distilled water is sometimes used to
wash the boards after assembly but it is less desirable than other
(toxic) solvents because of its corrosive nature.
I don't have problems if the distilled water is stored in glass or
certain hard plastics. Anything that has a silicon gasket causes me
problems, even if it isn't immersed in the water. However this only
applies to storing water after distillation, not during/before because
my distiller does have a silicon gasket in the chamber, and I don't
react to it.
