For chrissakes, everyone *knows* not to use acid-core solder for
wiring connections. The fact that we're even talking about it here
is totally ridiculous.

But don't take my word for it:
http://www.scienceprog.com/reliable-...ng-with-fluxes

They say "You should never use acid fluxes in electronic device
soldering and repair, as it will cause corrosion and even can
short-circuit device where gaps between tracks are small."

Sheesh.

I never said acid - that's you jumping to conclusions and getting it
wrong.

You said, and I quote:

I keep a tub of active plumbers flux ready to hand.

That stuff is acid flux. Wrong flux for wiring.

He means for ****ty 20 year old automotive or marine wire thats got
so much corrosion on it you can't brush it up. I've seen wire like
this plenty of times and rosin core flux won't touch it. I usually use
cripms on this kind of job, but acid flux also works.





Idea;
use one those anti-fluxes first to block acid flux from getting up where
it
can't be cleaned off,before soldering. Like the Tix anti-flux.

I still would try Tarn-X first to clean the corrosion off the wire.


I think Tarn-X is a good idea. I've never thought to use it.
I hate working on wire in this condition, but sometimes you have to. So next
time I'll try the tarn-x and see if it works.
