[TowerTalk] Cleaning Tarnished Wire

[Gedas]

As much as I hate to admit it, at times I have been guilty of leaving rotor 
cables or even coax outside unprotected from the rain and snow.  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?
