Here's a little trick I learned several years ago.
After scrubbing endlessly at caked on gunk in my microwave,
I was introduced to the most efficient way to clean my favorite kitchen appliance.
No effort, no fuss.
What You Will Need:
1 quart glass or ceramic bowl (or larger)
1 cup water
1 cup vinegar
Combine liquids in bowl.
Microwave for 5 minutes.
Carefully remove bowl after time is up.
Wipe with a damp cloth.
No scrubbing necessary!
This is a great task to do while washing dishes.
