How do I remove a burnt smell from my Microwave oven?

 To remove a burnt smell from the microwave, try the following: 

• Clean the interior of the microwave with a solution of vinegar and water or a grease-removing cleaning fluid. 
• Place two cups of water in a microwave-safe container, along with either some vanilla extract, 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 then let stand for ten to thirty minutes without opening the door. 
• Repeat if needed.
