Crown Spray Power. I take the door off and lay it flat. Spray it on and wait 2 or 3 minutes and you can wipe the black off with a paper towel. It rolls right up. Beats the heck out of scrubbing and scraping. Haven't tried it while the stove is hot but I bet it will work just as good. You can get it at Walmart,dollar stores, just about anywhere.
