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.



back when TEK tube scopes were common,I used to use Tarn-X in a spray
bottle to clean the silver switch contacts,then wash the entire scope,then
3 days in the drying oven.It saved having to replace some complex switch
assemblies.
