I have a "continuous clean" oven. Never had to clean it.
Actually, the door and the bottom of the oven are usually not "continuous clean" coated. So the oven door, the oven bottom, the racks, certainly the oven window and the broiler compartment (if gas rather than an electric oven, and separate from the main oven cavity)do probably need some major touch-up by hand.
In my opinion, the catalytic (continuous-clean) coating for a toaster-oven were nice. Can't seem to find those easily now, either.
I have cleaned many a gas oven by hand in my day. Cleaning an electric one with exposed bake and broil elements is just a pain in the ass.
BTW can anyone please share with me how the bake element is now hidden in an electric oven? How is the heat directed into the oven rather than up the sides of the oven cavity (from the outside). Lovely concept, but spills now burn even more-so as they land on the hot metal of the oven's bottom. Why were plug-in oven elements done-away with? They would seem seem to make oven cleaning, and replacing the elements, a breeze
The way to make all oven cleaning easier is to soap down the entire door, the oven floor in a gas oven (and about two inches in from door all around the seal AFTER EACH USE. Particularly after broiling. Rinse twice. (Be sure door is cool or glass window may crack). This will prevent the grease from baking-on upon the next use of the oven. It will also make the oven LOOK and actually stay a great deal cleaner for a lot longer. The dirt an grease on the top and sides won't be as readily apparent to guests as the door and bottom would be. This way you can let the hard-to-reach areas really get dirty to merit the use of the pyrolytic self-clean cycle.
For the nay-sayers, self-cleaning oven are insulated so much better/more than standard-clean ovens that the energy saved during each use makes the energy used during pyrolysis (self-cleaning) less of a concern. The cost of energy is less than the cost of the chemicals and said to be "greener" overall. [this post was last edited: 10/30/2011-22:18]
