Looking good!
Simple Green won't cut that baked on stuff. If you get a can of Oven Cleaner, Easy Off, (don't buy the cheap brand, it don't work as good), you could of had the lid and bowl done in a couple hours. Take the Aluminum ash Ring and bucket off so the oven cleaner don't mess it up. Spray it on, let it sit for awhile, then use an SOS Pad or scrape it off. Repeat if needed till clean. Wash with soap and rinse it good with water. Makes the job so much easier!
