Cue post of mahoosive fry up with black pudding in 3-2-1...
Stone me, you must be psychic!
Or maybe that was a cunning bit of NLP.
Is it possible to season or repair non-stick pans that have gone crap??
It's not worth the candle, SM.
If it is a really good carbon steel wok it might be worth sanding the coating off and curing it as per normal. It won't come off easy and you will probably need a power tool.
The bastard irony is that the coating flakes easily when you don't want it to but sticks like shit to a blanket when you do.
I was given a Ken Hom carbon steel wok and the Teflon (or whatever it is nowadays) started coming off very quickly. I gave it a really hard scrub with wire wool to remove the flakey bits but the rest is resistant to removal by hand means. I use it and rub it with oil after washing it but will bin it and buy a new one.
Ironically my Lidl 12" non-stick frying pan is in perfect order after four years and cost one third the price of the Ken Hom shite.
