Cooking with cast iron...

[NotAllowed]

I told you this ages ago.
Sodium hydroxide aka caustic soda aka lye.
Similar to over cleaner but they rip you off with that.
It will remove any traces of anything biological.
Then you have to season it.
Rust needs an acid like hydrochloric acid. All this works on anything other than aluminium.
What meat did you cook? Are you ever going to tell me that?
All I wanted to know is what you cooked lollllllllllllllllllllllllllllllllllllllllllllll
