I thought everyone cleaned their microwave this way, but just in case you haven't heard,
the absolute easiest, tried-and-true, neverfail way to clean your microwave is this:
Microwave a bowl of water with some lemon slices for about five minutes. When it's done, open the microwave and let all that lovely citrusy steam escape, then effortlessly wipe out with a paper towel. Easy peasy lemon squeezie.
