The default for most self cleaning ovens is 4 hours but if your oven is not that dirty, you can set it for less. I have not ever had a self cleaning oven that allowed for more than 4 hours. That would be a waste of energy as well as being highly unnecessary.
If you have a self-cleaning oven, you can use Easy-Off for self-cleaning ovens which will be less harsh on the porcelain finish. You can also use the Ammonia method: First, turn the oven on, let it warm to 150Â°F (65Â°C), and then turn it off. Place a small bowl containing 1/2 cup ammonia on the top shelf and a large pan of boiling water on the bottom shelf. Close the oven door, and let it sit overnight. The next morning, remove the dish and pan, and let the oven air out awhile. Then wipe it clean using the ammonia and a few drops of dishwashing liquid diluted in a quart of warm water -- even old burned-on grease should wipe right off.
