How Long Does a Self-Cleaning Oven Take?

Before the self-cleaning cycle is started, the oven racks must be removed and any liquid spills wiped from the bottom. Once the self-cleaning cycle is turned on, the oven locks and heats up to 880 degrees Fahrenheit for around three hours. When the self-cleaning cycle is over, the oven turns off, cools down and then unlocks the door. Ashes are left behind and should be swept out with a dust pan and broom.
