How do self-cleaning ovens work?
The basic idea is “burn baby, burn!” Self-cleaning ovens use an approximately 900 degrees Fahrenheit (482 degrees Celsius) temperature cycle to burn off spills leftover from baking, without the use of any chemicals. A self-cleaning oven is designed with a mechanical interlock (patented in 1982) to keep the oven door locked and closed during and soon after the high-temperature cleaning cycle, which can be approximately three hours. The door stays locked to prevent burn injuries. You can open the oven door after the oven cools to approximately 600 F (315 C). Self-cleaning ovens have the added benefit of more insulation, which helps the energy efficiency for regular baking. This is similar in concept to an increased R-factor for home insulation. You will also save energy costs by using the self-cleaning cycle right after baking, to make use of the already partially heated oven.
