Method 2: Baking Soda Paste for Tough Stains

For caked-on grime and stubborn stains, baking soda works wonders.
Steps:

How To Remove Odors from Your Microwave
If your microwave smells even after cleaning, here are a few odor-eliminating tricks:

Cleaning the Exterior of the Microwave
Don’t forget the outside!
