Cleaning the microwave oven is one of the nastier house cleaning chores. Here is a solution to make that job much easier.
Pour 1/2 cup vinegar plus 1 & 1/2 cups water into a large microwave-safe bowl. Place bowl in microwave. Set microwave on high. Heat vinegar and water solution in microwave for 5-6 minutes.
Carefully remove the HOT bowl. Wipe down microwave’s interior sides, top, and bottom with cleaning cloth. Even hardened food should wipe up easily now.
