Ethanol does the same. I?m not sure why isopropanol would be more popular for this use in
industrial settings. Perhaps because some plastics tolerate it better? (Plexiglas
doesn?t like ethanol, though it?s unusual in that respect.)
The classic organic chemistry lab procedure for cleaning/drying stuff is: (1) rinse with
water, (2) rinse with ethanol, (3) rinse with ether. Step 2 takes away the water; step 3
takes away the ethanol.

I wash/scrub heavily "soiled" boards
with soap and water, but then douse
them very very liberally with denatured alcohol. Denatured alcohol has the
property of getting into every tiny nook and crevice and forcing the water
out - so nothing potentially corrosive can be left behind to oxidize, etc.
Isn't isopropanol more suited for that as being highly hygroscopic it
sucks in water naturally before evaporating and taking it away with
itself? It's used professionally for cleaning PCBs in production too.
