It's more of a kitchen tip than a cooking tip; regardless, a grungy microwave keeps Shirley up at night. Here's her hack to keep your microwave squeaky clean:
1/2 cup of water
1/2 cup of white vinegar
Damp sponge or microfiber cloth
1. Place the water and vinegar in a bowl and microwave on high until the mixture comes to a rolling boil and the window steams up.
2. Allow the microwave to cool for a few minutes, then easily wipe the interior down with the sponge or cloth.
Oh and don't forget to clean the microwave keypad while you're at it!
