That stuff is acid flux. Wrong flux for wiring.

He means for shitty 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..

So you actually don't know what is or isn't in it. (I don't either.)
Might be worthwhile rooting around to try to find its contents (either
online, in a MSDS or from a supplier). My guess is that it is, in fact,
an acid flux.

I think you misunderstand RoHS and other regs; they don't seek to ban
anything corrosive, just regulate substances that are hazardous. I
seriously doubt that acid fluxes have been banned outright, or that they
ever will.

Capillary action will pull acid up the insulation when heated and down the
road the joint will fail.
