[sdiy] Removing flux from PCBS?

[Harry Bissell Jr]

If it is old rosin core flux... I use a slightly
dull scratch awl and crack / flake the flux off.
This removes 99% of the flux.  Then I scrub (dry)
with a nylon brush.

You could follow that with alcohol or a commercial
flux remover... 

Using chemicals right away makes a major gooey MESS.
Srcape first

In most cases I never use the chemicals, excpet maybe
a drop around a VCO or S/H cap...
