Easy tip to clean microwave:
I use a kitchen sponge, but don’t want it to be a hotbed of germs. This is how I keep the sponge and my microwave clean.
1. Once or twice per week, rinse sponge with hot, soapy water. Squeeze out excess.
2. Add a few tablespoons white vinegar to the sponge (until it is fairly saturated).
3. Plop the sponge into the microwave and nuke on high for about two to two-and-a-half minutes. Let cool for 1 min.
4. Remove warm sponge. Wipe out interior of microwave with moist cleaning cloth or paper towels.
The combination of heat and white vinegar helps kill germs in the sponge and the steam produced loosens grime in the microwave, making it easy to wipe away.
