If its the non stick itself then you are stuffed.

IME nothing takes hard carbon off anything except abrasion.

What is 'hard carbon' anyway? Sadly, it's not diamond, or we'd all be rich,
but it's not graphite either, as that's soft stuff that would wipe away
easily.


My guess is its a polymerised part of the fat with a high carbon content
but where all the free molecular ends that respond to alkali and soap
are simply absent

Probably some sort of ring compound resin..similar to whatever is in
bakelite :-)
