Distraction from the microwave cooking process may result in a microwave fire. Like any other kitchen fire, a fire in the microwave oven results in smoke and a strong, lingering odor. The smoke smell will remain in your kitchen and surrounding rooms until you get rid of it by using the correct cleaning supplies and techniques.
Fill a bucket with 1 gallon of warm water. Add 1/2 cup of ammonia.
Put on rubber gloves to protect your skin from the ammonia mixture. Soak a clean cloth in the diluted ammonia.
Wash your kitchen surfaces to remove smoke or soot film that contributes to the odor. Rinse the cloth as necessary.
Pour 1 quart of water into a cooking pot. Cut a lemon into slices with a paring knife. Add the lemon slices to the water. Bring the lemon and water mixture to a boil. Adjust the heat to allow the mixture to simmer.
Fill small bowls halfway with white vinegar. Leave the bowls in the rooms affected by the smoke smell for two or three days to absorb the odor. Replenish the vinegar as needed.
