I don't think anyone likes cleaning a microwave. Let's face I don't like cleaning anything. If you are as busy as me you don't get the chance to wipe it down every time you use it and it starts to get splattered and smell like the food, then this is the best trick for you. I bought a book a long time ago called the Queen of Clean and learned a very cool trick to cleaning my microwave easily and it smells wonderful when I am done.
1st cut a lemon in half and stick it in about 2 cups of water in a microwave safe bowl. I added another old piece of lemon just because I was about to throw it out anyway. 2 nd put the bowl of water and lemons in the microwave and cook on high for 3 minutes. Sometimes 3 minutes is just enough depending on how dirty the microwave was. If it is very moist inside and all the stains look wet then you are done. If not do it for another 3 minutes. 3 rd remove the bowl and plate and spray with a mild cleaner. You don't need the cleaner but makes it just that much easier to wipe. I have used cleaner on the tougher messes but most of the time you don't even need a cleaner. 4 th wipe with a sponge and clean your plate and it should turn out sparkling and smelling like lemons or no scent at all.
