Given my recent extended cleaning sprees, I thought that I could share a household tip. The easiest way to clean a microwave is to fill a small microwave-safe bowl with water, add a squirt of lemon juice, and then microwave it on high for five minutes. Keep the microwave closed for a minute or so after the timer buzzes.
The steam loosens any caked-on splatter. The lemon freshens. All you need to do is wipe the microwave clean with a damp cloth, no elbow grease required.
* This method was tested when I returned from church today. I accidentally exploded leftovers in the microwave while rushing to feed the girls before the little ones napped. Worked like a charm.
