Good afternoon, everyone! Recently, I came into the possession of a couple of new old skillets. The seasoning is pretty messed up on them (I think the previous owner's idea of seasoning a skillet was to never clean out stuck-on food). Anyway, I've been trying to remove the seasoning so's I can make a new one... But the old is very, very resistant, especially in the built-up areas (over 1/8" in places). Baking soda slurry overnight only did so much. A wire wheel didn't do much more. Easy off didn't touch it. Are there any suggestions out there? I don't have a self-cleaning oven. I also don't have the facilities for a bonfire in my backyard (or anywhere nearby). Right now this is a half-completed project taking up space in the kitchen. HELP!
