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:

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.


Actually I doubt the plumbers flux I use is acid.

UK building regulations are also affected by the dreaded RoHS so things like
corrosive fluxes aren't allowed any more. It was some years ago that
building suppliers stopped stocking Fry Fluxite (zinc chloride) I still find
uses for this flux in certain jobs and finally found a power tool supplier
that could order it..
