How about "Tarn-X" which is sold as a cleaner
for copper cook ware? Have you tried that?
I've had good luck with liquid flux that is
sold for soldering copper pipes. Works like
magic on my wires. I guess you already tried
that and it didn't work.
BTW, Ketchup = Vinegar, or am I missing something?

Later on, wanting to put it to some use and after stripping off some
insulation, I find that the surface of the copper conductors have been
tarnished with a nice black coating. The tarnish makes it impossible to
solder to even with an acid core flux. Other than physical abrasion,
does anyone have any tricks or solution/chemical that will remove that
tarnish?
