-> Ron and gang.......Been a long time, but seem to remember that years
-> ago, it was found that using achohol to remove flux was a no-no
-> because an achohol and rosin mixture made a mild acid, and left a
-> stickey residue ! The boards

I read somewhere to use the type of alcohol that's used in the doctors
office...it's a higher percent alcohol than regular shelf brand. I've
never used any cleaner, per se, on any of my (3) kits. What I did do on
my 38s was get a small brass-wire brush and scrub the solder-side of the
board. It kinda dulls down the "shine" of the solder-joints but it
removed most all of the residue on the board. Looking at the side-panel
on my Kester "44" rosin-solder it reads "...completely non-corrosive and
electrically non-conductive." I don't thing I'll worry about cleaning
the boards anymore. One thing scrubbing the bottom of the board showed
up was some little air-bubbles in a couple of the solder joints....as I
scrubbed the solder must have been very thin over these bubbles because
a hole would show up where the bubble was. I reheated and added a dab
of solder...things seem fine now. FWIW.
