When my oil cooler let go I had oil on the LH side header which burnt off leaving a lot of staining on my ceramic coating.
Tried several times to get it off but no real results,about to try acetone after that I'am lost for idea's.
TIA

Lacquer thinner

Thanks Mark will try it.

I'd see what the coating people say. I'd be tempted to use oven cleaner to remove carbon.

Don't know who did the coating,won't be putting on what you suggested sorry too expensive to risk that,had some success with the thinners but not easy...baked on .

Ceramic coatings are porous unfortunately.. they stain extremely easily, and can be almost impossible to clean once the oil is baked on..

At least they're on the bottom side of the car..

If it is a JetHot ™ style coating, and you haven't driven + baked it on the coating for too long : I have used a mild dish soap solution with a fine scotch brite pad. You are basically just burnishing down the coating very finely, but really depends how long it was driven and baked on.

Thanks Marty,emailed the OP and he just replied saying it is that style of coating,not driven much like this, .
Will report back when I'am on jackstands again .
