Vinegar steam clean.

White vinegar heated with water creates an acidic steam that dissolves grease and neutralizes alkaline odor compounds trapped on microwave walls and ceiling. The initial vinegar scent dissipates within minutes, carrying unwanted smells with it.

Method

Combine equal parts white vinegar and water in a microwave-safe bowl. Heat on high for five minutes, then let the bowl sit with the door closed for two to three minutes. Wipe the softened residue and moisture away with a cloth.

Effectiveness

Vinegar is one of the strongest natural deodorizers for enclosed spaces. It handles heavy odors from fish, burnt food, and spice buildup better than most other household remedies.
