I did a stupid thing! I put my new Mac exhaust system on with greasy hands and didn't bother to clean the pipes before running the engine. Now my fingerprints are all over the pipes stained in blue. Has anyone tried anything that even remotely cleans them up? I don't expect to get all of it off, but I'll take as much as I can.
I've tried metal polish, but it only makes the blue shinyer. I just figured it couldn't hurt to ask.
