Here’s how to disinfect and deodorize a kitchen towel and clean your grimy microwave all at the same time. Rinse your kitchen towel in the sink, and ring out the excess moisture. Place it inside your microwave and zap it on high for about 2 minutes. The microwave will disinfect the towel by heating it up, while the moisture from the towel releases steam, loosening up grime and making cleanup a breeze. Just wait a minute before wiping away the inside of the microwave with a damp sponge -- or use the towel inside and then launder as usual.
