In this video, Charlie from Mr. Appliance shows us how to clean ovens and microwaves. When any cook top becomes stained, it's always best to clean it right away or it will stain easily and be harder to clean later on. When you use the self-clean option in your oven, make sure you remove the racks as well as any big fool spills that exist in the oven. Microwaves should be easy to maintain and the best way to clean is with soap and water. You can also place a bowl of water and microwave it for around 3 minutes which will make it hot and steamy and easier to clean.
