I don't think even the old Methylene Chloride "Nitromors" will touch
the worst of it. Boiling, strong sodium hydroxide solution probably
gives you the best chance. Not recommended unless you are used to
handling aggressive chemicals.

The lacquers from oxidised oils and greases are *very* chemically
resistant. Otherwise you are down to mechanical methods (wire brush,
sanding disk).

Sodium hydroxide, (dangerous, 1 drop in the eye and you are blinded)
I think this is what the `oven cleaner companies` use but in gel form to
avoid splashes.
it would help if the parts concerned could be diassembled and taken
outside and soaked in a tray for an hour.

When were were students, a place we rented had a Baby Belling cooker. It
was pretty grim when we moved in- various oven cleaners didn't really do
the job.

I mixed up some strong NaOH sol., immersed the bits I could, and used a
paint brush to apply the rest- covering it with kitchen roll and cling film.

After maybe and hour, I cleaned it all off and there wasn't a trace of
old grease etc.
