Technical Burnt oil

Anybody have any suggestion on how to get burnt oil off jet coated header,tried paint thinner?

 

Starting fluid seems to get rid of oil stains on other things. Try it on a warm header, not a hot one.

 

I think that I would try a non-clorinated brake cleaner before I would use starting fluid on a header. Also diesel fuel or kero on a rag usually is good for cleaning oil type stuff. Perhaps even some tar and bug remover? I would use them on a cold header only.

 

I have ceramic coating on my headers on the 34 and I used Mothers on it and it came right out. Stunk a bit when it got hot but it went away and the so did the stain. I really should buy stock in that company.

 

^X2, it worked for me also

 

'48 Caddy porcelain exh manifolds were oil stained, I had some lacquer thinner, took it right off.

BUT... Modern days, I like Mother's, as Billy said.
Hell, I like sisters and daughters, too...long as they're not mine...

 

Speedway sells a "purple polish" that works for me on some roadster headers from Patriot that are ceramic coated to a chrome style finish.

 

X-3 always works for me just did it on my roadster headers
