(If you want to see what that is all about, though totally
unrelated to this thread,

Seriously, your washing of circuit boards isn't as silly as people here
seem to think. The manufacturer washes flux off in what amounts to a
Pro's have beening doing that since day one. It was a little
difficult back in the days of electron tubes because only the
highest quality equipment used hermetically sealed coils and
such, so only the high quality equipment could be put into a
dish washer. We used to do it all the time with various
components of troposcatter radio systems, and for years and
years I had the most sensitive tropo receiver in Alaska. (This
was reported year after year by the QC inspections, and I got
lots of questions about how and why, but (you guessed it) they
didn't believe me...
dish-washer. I don't think I'd want to leave a soap residue though.
Analogs certainly wouldn't like that much. A DI or distilled water
rinse would seem appropriate.
Actually, you *do* want to leave a film of wetting agent on your
motherboard. That will retain just enough moisture to dissipate
static buildup (for example from the air blown into the case by
fans) and will reduce the amount of dust that is attracted and
sticking to the motherboard.
It has about the same effect as an air ionizer.
Which is to say, the motherboard will stay cleaner for longer.
BTW, that's first-aid for electronics (and even cameras) after being
dropped in water. Take out the batteries immediately, then dunk in DI
or distilled water as soon as practical. ...cook on low heat until
done.
Incidentally... that is true of gasoline engines too!
