Cleaning an oven sounds simple but just try to research about it in the internet and you can discover just how many different tips and tricks people are reading just to know how to do it the right way. It basically depends on the person who owns the oven. I saw someone sharing a video on how she cleans her oven and she uses a commercial oven cleaner as if it was just plain water. She doesn't ware protective gloves and just sprays the cleaning agent liberally.
For someone who knows better, that is not the wisest thing to do. These cleaners contain lye which can be very poisonous so for someone who is a more environmental and health conscious, this approach is definitely not acceptable. Some would want to use the more natural cleaning products like baking powder or even vinegar. Sounds OK, but it sure has the tendency of making your next casserole taste like vinaigrette.
This why companies have created and manufactured the self cleaning oven that uses high temperatures of 900 degrees Fahrenheit to burn off spills that were leftover from baking without the use of any chemicals. Just wait for its auto lock feature to turn off and you just clean off the remaining residue.
The problem with self cleaning ovens is that there have been many reports that the fumes coming from the self cleaning process can be very dangerous and not only to humans but for animals as well. Although there hasn't been any clear and formal study if it can cause cancer, would you risk you family exposing them to this hazard in your very home?
Probably the last and best option that you have is to simply hire a professional oven cleaner to do the job for you. Most of these oven cleaning services use natural and environmentally safe cleaning agents to comply with good company standards so you can be sure your family's health is secured. A professional oven cleaner is trained to clean your oven properly saving you time and worries of being exposed to any dangerous fumes. So if you are not completely sure about using that self cleaning function, then it's a risk not worth trying.
