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 :-)

I wonder what's in oven cleaner? Some strong oxidising agent?


Its pure caustic soda in a foaming agent.

It will get off 'brown' fat but not 'black' fat.

You need a fair amount of it to get off thick deposits, and its not kind
to aluminium. You need to wash anything down bloody well - a mild acid
like vinegar is a good tip - if food is going to come in contact.
