the rust is in the area right below the plug that i plug into my amp.i got the rust from when my mom's cat knocked over my fish bowl and my cable ended up getting wet on that one end.
If the plug is chrome plated, here's a solution I seen used on car bumpersTake some aluminum foil and crumple it upDip it in Coca-Cola, and then use that to remove the rustHow well it works depends on how deep the corrosion isFollow with clean water and then dry it wellBut, you should have a spare cable anywayCables are the weakest link in an electric guitar (or bass) setupNever leave home with just one!
