  Oxalic acid is typically marketed as a wood bleach in hardware stores. It costs less 
  than 10 bucks. All you need to do is mix a few ounces of Oxalic acid in a large tub 
  of water, and soak the parts for 12-36 hours. You simply wipe the parts "free of the 
  rust" occasionally with a white (soft, non-abrasive) scotch-brite pad, and you are done. 

  The pitting will never go away, but you have not added any steel wool scratches, or 
  scotch brite scratches, or any other damage. In fact, it will often leave the decals in tact! 
  Especially if you cover them with tape first!

  ...Oxalic acid, White scotch-brite, and a tooth brush. Nothing more, nothing less...
