I’ve found a great way to clean my microwave. I take a rag, wet it, and ring it out—but not tightly. I place it in the microwave and turn it on for 25 seconds.
When I open the microwave, the rag is hot enough to remove any buildup but not too hot that I can’t hold it. I use this to wipe out the microwave and it works every time in a matter of minutes.
I got the idea from those expensive microwave cleaner packs that work the same way. Debbie
