There are few things more disgusting than opening a microwave oven to find cooked-on extraneous matter clinging to every surface. The way to avoid this, of course, is to clean the appliance thoroughly after every use. Or unfortunate explosion. Uh-huh. Right.
Let’s get real. A microwave with frequent use, whether at home or at work, doesn’t get a thorough cleaning every single time. It’s going to get dirty so it’s good to know how to clean it effortlessly. With steam!
Steam cleaning a microwave oven is super easy with ordinary plain white vinegar and water.
Step 1: Vinegar and water
Pour one cup plain white vinegar and one cup water into a microwavable container like a glass bowl or measuring cup (as a safety precaution stick a chopstick, skewer, or wooden spoon in the cup to prevent the unlikely occurrence of exploding water). Place it in the microwave.
Step 2: High for 5-10 minutes
The more challenging the situation, the longer you want the water and vinegar to steam away. Keep an eye on it, however, as you do not want the cup or bowl to boil dry.
Step 3: Remove container
Very carefully, using an oven mitt or potholder, remove the cup. Notice how all interior surfaces including the door is dripping wet with hot steam.
Step 4: Wipe it clean
Using a sponge, cloth, or paper towel, wipe down the oven’s interior—so easy because the steam has softened and melted every bit of goo and grime.
*A reasonable substitute for plain vinegar is lemon juice—either bottled or freshly squeezed, in which case throw the lemon rinds into the cup as well.
