I stream clean my microwave regularly every week in two of the following ways with a "hothead" or stream cleaner which I also use in the bathroom with hand scrubbing the floor. Two of my co-workers got on the subject and told me I was crazy when all that they do is wipe the microwave out with warm water, dish detergent, and bleach. Cutting corners to clean is not my thing. To me when it's done right it does show. My coworkers think I am crazy with cleaning the microwave and using a stream cleaning, as well as around the house. Hell I even do my bed twice a month, and my curtains every three months.
I was told that when you clean a microwave it will take away the flavor of your food. One thing about NA/AG you learn new things. I will clean mine this weekend
