How to Remove Microwave Smells
A microwave oven, like any other kitchen appliance, needs to be cleaned regularly so that it continues to work well and lasts for a long time. If not maintained properly, it can emit a smoke smell or other unpleasant odor.
Cleaning the Filters
Most over-the-range units have two different filters that need to be cleaned or changed regularly.
Charcoal filter: This filter absorbs pollutants from the foods you cook on your stovetop. The filter is made up of tiny pores located on the surface that trap the toxins and smoke smell. Over time, the pores get filled up. When that happens the filter will need to be replaced. Most manufacturers recommend that you replace your charcoal filter every six months. If your over-the-range unit has vents that blow air directly to the outside of your home, however, the charcoal filter doesn’t need to be replaced because the air in the hood is not recirculating.
Grease filter: This filter should be cleaned out about once a month. Just soak it in hot water and detergent and then gently remove any debris with a soft brush. It’s important to remember to avoid using any cleaning products that contain ammonia. If you have questions about how frequently to clean the grease filter, refer to the owner’s manual.
General Cleaning: You should never allow food particles to build up on the inside walls of your unit. Wiping the walls down with warm water and dish detergent after each use will make it easier to keep the appliance clean. Crusted food is hard to remove and it may also prevent your unit from working properly. You should also keep the vent grill clean by wiping it gently with warm water and detergent regularly.
