The microwave in my house tends to get a build up of dried on food spatters. As I do my weekly cleaning, I put a glass bowl that can hold about a pint of water and turn the microwave on for about 10 minutes. The steam from the water helps loosen dried on food! I do other cleaning while the bowl is in the microwave cooking. Most times I just wipe it all out and then rinse with bleach-water. For tougher food spatters, just repeat!
