Alumimum foil works...
If you have to or even just want to reuse a cosmetically challenged inner cable, simply rub it with crumpled up aluminum foil. The foil will remove most of the oxidation and color the cable its natural silver color. That said...
I agree with others. If you can replace the cable with a new one, do so. It is the best way to go.
