How to clean burned material of the exhaust headers?

[zenbiker]

I use a compound called Blue Job. It gets the hardened mess off and leaves no marks. Available on e bay.

Blue Job is gerat on chrome but will buff out the satin finish on the headers.

A bit of sugar and elbow grease

Try packing with ice ,wait till it's as cold as the ice then try chiping it off carefully it might work .

I've always used the cold Easy Off oven cleaner with never a problem. Spray on and leave alone for 24 hours. Then wipe off.
Will not harm the finish!

Does the Easy Off cleaner work on the 2.5s?

will oven cleaner work?

Here is a video I found about cleaning burnt plastic off pipes. Might work for you. I personally used my TubO'towels wipes on very warm pipes three or four times until it all came off and then chrome polished it back to shiny.

Depending on how much crap is there, I"ve used WD40 in combination with a razor blade to scrape off any burnt off crap from polished stainless sidepipes. The WD40 provides enough lube to avoid scratching.
