Bill Krier, president and CEO of highly the rated Broad Ripple Appliance in Indianapolis, recommends cleaning your microwave regularly to remove food particles.
“Even though it’s stuck on there, the microwave is going to keep heating the food pieces,” he says. “After time it’s going to get hard as a rock.”
Krier says microwaves heat food particles at high temperatures, which can then burn the top and sides of the microwave. He recommends cleaning the inside of the microwave with glass cleaner.
To remove stubborn food bits, boil a cup of water or white vinegar in the microwave to loosen the food particles, which you can then easily wipe off with a sponge.
