Oh, too true -- I found this out to my cost while I was building the
DiscFerret boards. "Electronics grade" isopropyl barely did a thing to
the flux without a long soak and a good scrub with a toothbrush,
followed by a rinse in fresh IPA.
Now what *does* work well is Chemtronics' Flux-Off, which AIUI is
acetone-based. Spray it on and the flux starts dripping off the board.
There's a brush attached to the end of the aerosol can, but it's only
really of use for reducing the amount of F-O you need.
Only problem is, it's about ?8 for a 200ml can (!)
What I really want is something that comes in N-litre drums or tin cans,
evaporates a bit slower than Flux-Off but faster than IPA, and removes
Multicore's rosin-based fluxes. Haven't found anything like that yet,
though :(
