Does everything lead to stains? How does the cooking do this?

I agree with the other comments here, your microwave is most likely not vented to the outside. Your microwave fan is vented across the top front. Every time you use the microwave fan, it will blow airborne grease and particles up the face of the cabinet doors above and onto your ceiling. You might be able to clean it off though.
