Kitchen hack for cleaning the microwave

Maybe most of you already know this, but I somehow never thought of it until a couple of days ago.

Wiping off the inside of the microwave is so much easier, quicker, and more effective, if I microwave a bowl of water for a few minutes first! Hot steam gets into all the crud on all the sides and top and bottom, and a single wet soapy shop towel can get it alloff in like a minute.
