I had a cheapo exhaust tip on my Saturn, it surface rusted over and I got alot of it off with brake cleaner surprisingly. Just spray some of that on there and wipe it off with a rag. Use a fine brillo pad to clean it off if that doesn't work.
i also read that steel wool + elbow grease (lots of it) + any metal polish will do a pretty good job on the rust spots
