How do I eliminate odors in the microwave? Easy! Clean the interior of the microwave with a solution of white vinegar and water or a grease-removing cleaning fluid. Place two cups of water in a microwave-safe container and add lemon juice or teabags. Place a wooden skewer or chopstick in the container. Heat on high for five minutes or until the water comes to a boil, and let stand for ten to thirty minutes without opening the door. NOTE: Repeat as many times as needed.
