Have you tried conc nitric acid ?Â* That should get it off, but

that easy to get.

what does that do9 to carbon?

Dissolves it.

No, it doesn't. Even fuming nitric doesn't.

Yes it does with boiling conc nitric.

There are limits to what I'll use as a cleaning chemical. Boiling
strong fuming acids are a good 2 steps beyond that point.

But there isnt anything else except molten potassium nitrate
that will get that carbon off without damaging the enamel.

The one or two detachable parts come clean after several cycles in the
dishwasher, just as an old baking tray with similar burned on fat will
do. Obv I can't soak the cooker hot for several hours, but I don't
understand why there is no norma cleaning product.
