I had bought a new carbon steel wok last year and as I had the afternoon to myself I opted to season it rather than play my guitar thru my amp at 11. I scrubbed it with super hot water and Dawn - twice then dried it on heat (It helps to have a honkin' good burner). Let it cool then I scrubbed it again then began the process of heating it all over till it was blue, let it cool then I scrubbed it again in hot soapy water then began again. At this point I heated it and wiped it with a paper towel with coconut oil and let the heat come up then wiped it dry and repeated. Now it's all shiny.
