When I had solder training (oh, 15+ years ago?) we used alcohol. We
used Flux Off or a Freon wash before that but when Freon was banned we
moved to alcohol. Not as effective as Freon but it does a good job. To
clean a board (like after I tinned it) just alcohol on a paper towel
does good. To clean after parts are mounted, take a flux brush, cut
the bristles down a little (maybe to 3/8") and scrub the parts with a
alcohol soaked brush, blot with a paper towel, rinse with a little
more alcohol and blot or air spray dry. A little messy but it works
well and it's what is usually used for the RA and RMA fluxes.
