That is the new (10 years old - new) almost environmentally correct
solder flux. It is citrus based (IIRC) and is meant to be washed off
the board with hot water and detergent. Do that and it is the simplest
stuff to use.

I knew it had to do with defluxing in a less polluting way. I had heard back
then at Bell Labs that someone had come up with a citrus-based defluxing agent
that worked on the usual rosin flux, but I must have heard it wrong.

I don't use it, though, because its fumes stink so bad that I am sure
they must be bad for me. So I continue to use rosin core solder, and
then use isopropyl alcohol to remove the flux.

I have no idea what burning orange peels smell like, though I'm sure kids tried
smoking them back in the 60s, along with banana peels :-)

You shouldn't leave flux on any solder joint. If you are steadfastly
determined to do so anyway, there are several fluxes available in the
Kester solder line that leave a very minimal amount of residue.

Surely you're not saying one should deflux a tube socket, wired chassis solder
joint? I can see defluxing PC boards, but I've never heard of defluxing a BA
style solder joint, and it would be downright near impossible. Well, maybe
with a dozen Q-Tips and an hour of work. Did factories deflux BA chassis?

Anyway, my buddy swore he'd deflux things now. And he'll be more careful to
read the label before buying any solder. --Mike K.
