Subject: Re: [Elecraft] ethanol/isopropyl
The denaturing agents in things like rubbing alcohol will leave
undesirable
residues as may the coloring agents used now in some rubbing alcohol.
Use Everclear, or pure Ethyl alcohol, (taxable by Feds) for circuit board
cleaning. Cut off the bristles of standard "Acid Brush" to half the
normal
length to get stiff bristle effect for scrubbing the soldered joints.
Acid
brushes seem to be stocked by Home Depot and Lowe's as well as wholesale
plumbing supply houses.
You want the pure stuff, without risk of residue.

I'll tell ya - then I got a question - for something as important
as MY rig, I'd spend the extra for the good stuff just to be sure.
Then, when done, I'd dump the bottle down the toilet.
Now the Q: Why is it so important to clean off flux residue?
