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
You should never use the clean function on the oven, even for cleaning the oven. It can severely limit the lifespan of the oven as well as cause other issues (especially if you have birds or other small animals).
Another problem with using it for “cleaning” CI is especially on more delicate, thinner casts like old Wagner, CHF, etc, it can cause severe warping of the iron.
