How to Clean a JennAir Built-In Microwave Inside and Out 1

Regular cleaning prevents odors, staining, and performance issues in your JennAir built-in microwave. Learn the best methods for interior and exterior surfaces.

Why Regular Cleaning Matters

Food splatters inside a microwave absorb microwave energy during subsequent uses, which reduces heating efficiency and can cause hot spots or even arcing. Baked-on residue becomes progressively harder to remove the longer it stays. JennAir built-in microwaves feature a stainless steel interior that is durable but can stain if neglected. Cleaning the microwave after each significant use is the easiest approach.

Steam Cleaning Method — Best for Routine Cleaning

  1. Fill a microwave-safe bowl with two cups of water and two tablespoons of white vinegar or the juice of one lemon.
  2. Place the bowl in the center of the microwave.
  3. Run at full power for 3 to 5 minutes until the water is boiling and the interior is filled with steam. The steam loosens baked-on food and grease.
  4. Do not open the door immediately — let the steam work for another 5 minutes with the door closed.
  5. Open the door carefully (the bowl will be very hot) and remove the bowl with oven mitts.
  6. Wipe down all interior surfaces with a damp microfiber cloth. Most residue should come off easily. For stubborn spots, use a paste of baking soda and water on a soft sponge.
  7. Remove and wash the turntable and turntable ring with warm soapy water. Dry and replace.

Cleaning the Interior Without Steam

If you prefer not to use the steam method:

  • Mix a solution of warm water and mild dish soap.
  • Dampen a soft cloth or sponge with the solution and wipe all interior surfaces — ceiling, walls, floor, and door interior.
  • For grease, apply a small amount of baking soda directly to the cloth and scrub gently.
  • Rinse the cloth with plain water and wipe all surfaces again to remove soap residue.
  • Dry with a clean cloth.

Cleaning the Exterior

JennAir built-in microwaves typically have a stainless steel exterior that matches the surrounding cabinetry or wall oven:

  • Wipe the exterior with a damp microfiber cloth.
  • For fingerprints and smudges, use a stainless steel cleaner. Spray it on the cloth, not directly on the appliance, to avoid getting liquid into the vent openings.
  • Wipe in the direction of the grain of the stainless steel for a streak-free finish.
  • Clean the control panel with a barely damp cloth. Do not spray cleaner directly on the controls — liquid can seep behind the panel and damage the electronics.

Cleaning the Vent and Grease Filter

If your JennAir built-in microwave is installed over a cooktop (over-the-range style) or has a ventilation function, it contains a grease filter:

  1. Locate the grease filter on the underside of the microwave. It is usually a mesh screen that slides or snaps out.
  2. Soak the filter in hot water with a tablespoon of dish soap and a tablespoon of baking soda for 15 minutes.
  3. Scrub gently with a soft brush, rinse, and allow to dry completely before reinstalling.
  4. Replace the grease filter entirely if it is damaged, discolored, or does not come clean after soaking.

What Not to Use

  • Abrasive pads or steel wool — they scratch the stainless steel interior
  • Oven cleaner — it is too harsh for microwave interiors and leaves toxic residue
  • Bleach — can damage the interior finish and leave fumes
