Salt has also been mentioned.

I wondered about using oven cleaner as a far more aggressive approach.

Anyway, any tried and tested remedies?

Heat pan with salt in it, Tablespoon to several tablespoons worth. Rub with
wadded paper towel, kitchen roll, wadded newsprint. Use lots of paper, or a
glove. Keep heating, stop just about when it smokes. Rinse etc.

Do NOT empty the hot salt into anything plastic or plastic-lined, but on
newspaper or such. DAMHIK.

This will shift more carbon that other methods because of the combination of
scouring and heat.

Oven cleaner -- will work, but not spectacularly well IME.
