I avoid steel wool as it will scratch. Chemically treating with oxalic acid, or Evaporust is better. Degrease the surface first. Or electrolysis works. For convenience and effectiveness use Evaporust.
any markings on the back of the rear derailleur?
Got and tried Evaporust...works wonders!
How much /size of the stuff did you buy, as I've only seen great big bottles of the stuff
