Over and over, I’ve been told to put my old, slightly mildewy smelling, wet kitchen sponges into the microwave to nuke the bacteria out of them.

So I tried it.

Still smells gross. But! After 30 seconds, the sponge put out enough steam to loosen the leftover crud on the top of the microwave. It was so easy to clean!

Still nuke that sponge but for a new use!
