Cast iron skillet smoking and smells like chemicals
I have a cast iron skillet that's a hand-me-down from my husband's grandmother, and I've probably never properly taken care of it. I do use soap, and I think I've only seasoned it once, and even with that I'm not sure if I did it correctly.
Anyways, I never really had issue with it until recently when I heat it up it starts smoking a ton and it smells like horrible chemicals. Does anyone know what this means, and why it smells like chemicals? Do I need to start over and season it? Also, since we got it, the inner surface has never been smooth, it has some, for lack of a better description, raised areas that I've never been able to get rid of (photo attached). Any ideas on what I can do to make this workable?
The bottom looks unseaseasoned.
I'd put in in the oven for a few hours at 450 and burn off whatever crap is on there and then reseason.

Not sure what does "smell like chemicals" mean, since all smells are from chemicals. I will assume you mean a repulsive kind of smell. This can be many things. If it smells metallic, then it is probably that you can a rustic pan. If it smells rotten, then you probably have rancid oil. If it smells like chemical solvents (like those household cleaner), then I have absolutely no idea.
Based on the photo, the pan can use a bit better seasoning. If you have food residue and build on crud, then you can scarp it off with a metal tool .
All in all, I cannot tell the damage done to the pan. I may opt for a complete reseasoning. You can find many articles on CHOWHOUND and other sites for complete re-seasoning. If you have specific questions, please let us know.
