If food spills in your oven, it will likely begin to burn and smoke, causing an unpleasant smoky smell in your home. You can stop the burning while it is happening with a simple home remedy. You will then need to remove the burnt-on food to remove the source of the smell and to prevent it from burning and smelling the next time you bake something in your oven.
Pour salt over the food currently burning in your oven. It will absorb the odor and stop it from burning. You can do this carefully while you are baking, or you can do it after baking if the burnt food is still smoking and causing more odors.
Remove the oven racks after the oven cools and wipe up any spills with a damp rag or paper towels.
Clean the inside of the oven with hot soapy water and a rag. Use steel wool to scrub away the harder-to-remove stains and foods.
Soak a rag with ammonia and set it on top of stubborn burnt-on foods. Let it sit for 30 minutes. Ammonia helps soften burnt or baked-on foods in the oven so you can easily remove them.
Rinse the inside of the oven well, using a clean rag and a bucket of warm water. Rinse the rag often, wring it out and continue to clean the oven. Change the water as necessary.
Set a bowl filled with an odor-absorbing material in and near your oven if you can still smell the burnt odor. Vinegar, baking soda and activated charcoal. Remove the material from inside your oven before you use the oven again.
