How to clean burned material of the exhaust headers?

[SPWL]

Use a copper coin as a scraper (make sure it is solid not plated). Test on a hidden part first to gauge how hard you can press, but to remove plastic residue very little pressure is needed. Then polish with metal polish as normal.

0000 steal wool genly first, increase pressure as needed.

I'm going to use a penny and 0000 steel wool, first on cold exhaust if no result I'll turn the engine on to heat it up!

Please use a bit of WD40 or equivalent on the 000 steel wool pad to avoid any scratch on your pipe. Make a try on a similar par of metal before trying on your exhaust.

Try the copper coin first, it works every time on cold exhaust, you don't need WD. I would never use steel wool it will scratch even if you can't see the scratches.

Very Happy with the result of Copper penny and the Autosol polish. The bronze finish will return once I start driving again
Thanks to everyone for sound advise.
Cheers!

I think I see charmed bug materials on my pipes. I use the chrome polish and elbow grease till it slowly come off. I just don’t want to use abrasives on the pipes.

Ice and a nylon scarper for rubber on chrome pipes, not ice chips thrown at it a big chunk of ice and work it

I know not applicable here but DO NOT UNDER ANY CIRCUMSTANCES USE OVEN CLEANER ON CERAMIC COATED PIPES.
Somewhere back in history on here is photographic evidence of what a bad idea that is.

Here you go. DO NOT UNDER ANY CIRCUMSTANCES.........
