Disinfect and Clean Your Microwave
The disinfecting properties of hydrogen peroxide are equally effective when cleaning your microwave. To clean the inside of your microwave, place a cup with 3% hydrogen peroxide solution and water. Turn it on and let it run for ten minutes. Afterward, wipe down the inner surfaces using a sponge.
Most people forget to clean the exterior panel of their microwaves when they are also rife grounds for bacteria. Use a hydrogen peroxide-soaked sponge to wipe down the outer surfaces too. Avoid spraying the solution on your microwave, though, because it might seep into the vents.
