What Microwaves Have Vents?

Not all microwaves have traditional vents that can be removed and cleaned. Countertop microwave vents, for instance, are simply used to disperse residual heat, so they won’t get greasy or dirty. Over-the-range microwaves, however, sit directly over oven burners, so these vents can easily become dirty and gross over time. Left unmaintained, these vents can become damaged and lead to further damage throughout the microwave, leading you to learn how to fix a microwave door hinge and related repair issues.

Place the entire vent in the container and let it sit for 20 minutes or so, rotating regularly so you don’t miss any part of the vent. Once that is done, remove the vent from the soapy water, rinse it off with warm water, and wipe it down to dry. Make sure it is completely dry before reattaching it to the microwave oven.

Toothbrush and Cleaner

You can use a toothbrush and a standard cleaning formula on a microwave vent. Just spray the cleaning solution on the toothbrush and carefully scrub between each vent. After, make sure the vent is dry by using a paper towel, a dishtowel, or clean cloths.
