I have a carbon steel wok but it became rusty recently when I forgot something in it for a day.
I decided to scrub everything off and re-season it. The problem is I can't get the center of the wok to be seasoned. No matter how much oil I add, it burns and disappears leaving the center as bare metal...
My method is applying a very thin layer of oil and making it burn on the gas, then when it's dry (and not seasoned...) I rub more oil. It worked for everywhere except the middle.
Should I scrub off everything again and start over? If not, what should I do?
