I used a razor blade to get the majority of it off very carefully and then a cleaner to wipe away the rest.
This by far is the most effective way to clean melted plastic and rubber off of pipes and heat shields. It is a procedure that takes a little practice (use a very shallow angle, as if youre using a straight razor to shave your whiskers). Once most of the crud is gone I use mothers chrome polish. The pipes end up looking new with out any scratches.
First reply was the answer I was going to give as well...Goo Gone or Goof Off. Finish with rubbing alcohol to get rid of any oily residual before heating up the pipes again.
I've tried all the above and for me nothing works better than a little WD-40 and a razor blade on a cold pipe. The razor blade has *never* scratched my pipes; probably because the WD-40 makes 'em kinda slick. Any and all burned on stuff comes right off, and the pipes look like new ....
Nother vote for EZ-Off. I heat the pipes up and use a cotton rag. DO NOT touch your hot pipe with a micro-fiber towel...don't ask me how I know, just don't do it.
