We gave you a great cleaning method for removing baked-on foods from the inside of your microwave, see
Easy Microwave Cleaning. However to remove stains and freshen your microwave make a paste of baking soda and warm water. Rub the paste on all of the plastic surfaces inside your microwave with a sponge. Wipe clean with more warm water and a clean towel. The baking soda will remove the stains and will freshen your microwave, removing all of the food smells!
