Homebrew PCBs

Professional plumbers use just a wet rag to wipe flux
off of freshly soldered piping, and ultrasound is
actually quite powerful.  There is a push in europe
right now to clean all wafers with just steam.  You
might try buying one of those 20 dollar harborfreight
ultrasonic cleaners, use water as your fluid, and let
them sit in the ultrasound for a half hour or so, if
you can stand sitting next to that annoying buzzing
for that long at your workbench.  You might stick all
your boards in once for a half hour, then drain the
water out and do it one more time with fresh water,
but that is a lot less labor than any manual cleaning
would be.
