I just tried this and it is wonderful. Take 1/2 cup of white distilled vinegar and place it in a microwave safe bowl. Then mix 1/2 cup of water with the vinegar. Place the bowl in the microwave and heat it to a rolling boil. It will loosen any caked on food and remove any odor. Afterwards just wipe down with a clean rag. It took me all of about 4-6 minutes.
