Suggested earlier oven cleaner Easy-Off would be the last thing to try. Yes, it removes almost anything. It also makes a lot of fumes that are either chlorine or sulfuric acid, really bad stuff, your throat would feel it immediately. Wearing gloves with this thing is a must, it's very damaging to skin.
I could use Goof Off in a big kitchen or a room if I had to, but Easy-Off I would only use in the open air, in short strikes, trying not to breath at all at that moment. Or wear a gas mask. There is a fume-less version as well, which must be either not the same stuff (= not same effect) or not really fume-less.
