Hello.
I am trying to find a modern equivalent to a plumbers flux used in the 60's and 70's.
It was a quite aggressive, maybe acid based white paste that was used to clean copper pipes and capillary fitting where the copper was badly tarnished.
I was great for jobs where it was well nigh impossible to get to pipes to clean them first.
It had to cleaned off with soapy water after using or a green copper oxide would form on any residue.
I can't remember the name of it but it was widely used in the plumbing/heating trade.
Does anyone know if there is a modern substitute, as I'm sure political correctness will have banned it.
Some modern fluxes are sold as, "self cleaning", but that does not refer to the substrate unfortunately.
Hope someone can help.
Mike.

I seem to remember that it was Borax powder. I suspect that I still have some somewhere Borax or not.

Solved my own question.
Having rummaged around the shed for a couple of hours I found a half full tub of the flux.
Still has the date on it, April 1970.
Tried it on a particularly tarnished piece of pipe and it still works perfectly.
It's called EVERFLUX ACTIVE FLUX PASTE by Wiseman Group Ingatestone.
Still sold apparently but no longer called Active and the makeup is not the same.
