I know it may sound weird but try Carb cleaner or Brake parts cleaner. Just be sure not to get it on your paint. I used it to get a bunch of stains off the bottom of my Big Dog motorcycles S&S 117 engine block. Wash off any residue and use a metal polish like Never Dull.

Dont know if it will work but it worked on my engine block when nothing else would work.
