This solution is about 70% vinegar. It smells horrible! Like vinegar and rust. I was grimacing the whole time doing this. When Id scrub it with the steel wool rust flakes would come off the surface and I could see clean metal under. I do this all while it's still submerged. There was a lot more rust ect than I thought there would be.
This is the old vinegar bath after a few days with the sheet steel:
After all surfaces were scrubbed while it was submerged, I quickly washed it off in the sink then put it in another bag with clean soapy water.
For taking it out of the water I had to dry and bake quickly because it starts to rust immediately. I had a space with towels to lay it on, and more to the side to dry it with. After hand drying it put it in a 200F oven for 8 mins and it was bone dry, then quickly slathered it with avocado oil to bake at 490F for 50 mins, leave to cool for hours.
The smoke it created was awful. Thick but did not set off the smoke alarm strangely enough. I had to vent the whole place, all fans going.
Im now baking it a 2nd time and there was so much smoke I had to read a book outside. After it cools I want to sand the surface a bit because the seasoning done this has beaded up in some areas. After that Ill try to make pizza with it.
I think the baking steel is very dangerous and should not be used by women and children. If you were to hold it vertically and drop it, it would easily cut toes off and it's a smooth surface to hold onto. I've developed this whole discipline with carrying it would in front of me with n edges facing down. If these become popular it's going to be even worse than deep fried turkey disasters.
