I think I posted this somewhere else, but a mild solvent works well (acetone applied lightly takes it right off), or if the car has a good layer of wax on it most liquid cleaning polishes will take it right off, while at the same time protecting it.

For the tips any good metal polisher will give those things a brand new look with a little elbow grease - I wish I had the stuff in front of me and I can't remember the name of it off the top of my head but there is one out there I started using my friend turned me onto that protects specifically against tars and carbon residues, so its perfect for the exhaust (just requires much less work to get the tips that brilliant shine afterwards)
