Not OP but when my pans got shitted up like this by crappy roommates I put the pans in the oven on the clean function. All the crud was carbonized. I then wiped off the ash, seasoned them with shortening, and baked them for a bit. You have to touch up the dry areas for a bit after with more oil but eventually the pan ends up properly seasoned with use
Pro tip: do this in the winter so you don’t make your house 100 degrees in the summer
What does that process look like to turn it from that into this

I had a bonfire and it took care of the crust just fine
