Remove Hard Grease From Your Microwave

Hard grease inside a microwave can be stubborn, affecting both performance and odor. This expert guide covers proven, safe methods to remove baked-on grease from the interior walls, ceiling, door, and turntable, restoring shine without harsh chemicals.

Safety first and prep

• Unplug the appliance before you begin and remove the turntable and roller ring for separate cleaning.
• Use non-abrasive sponges or microfiber cloths and a mild dish soap. Avoid metal scrubbers or strong solvents that can damage coatings.
• If you’re unsure about your model’s coating, test a small, inconspicuous area first and wipe clean with a damp cloth.

Best methods to tackle heavy grease

For hard grease, start with steam-based cleaning to loosen residues, then finish with gentle scrubbing and thorough drying. Repeat as needed for stubborn spots.

1) Steam cleaning with lemon (the most reliable method)

• Fill a microwave-safe bowl with 1 cup (240 ml) of water and add 2–3 lemon slices or 2 tablespoons of lemon juice. The acidity helps break down grease and deodorize the interior.
• Place the bowl in the center and run the microwave on high for 5–7 minutes, letting the steam thoroughly coat the interior walls.
• Carefully remove the hot bowl with oven mitts. The steam will have loosened the grease; wipe the ceiling, walls, door, and turntable with a damp sponge or microfiber cloth. This method is a simple way to clean microwave with lemon.

2) Baking soda paste for stubborn spots

• Mix 2 tablespoons baking soda with enough water to form a thick paste.
• Apply the paste to stubborn grease spots on interior surfaces using a non-abrasive sponge. Let it sit for 5–10 minutes to soften baked-on residue.
• Gently scrub in circular motions, then wipe away with a damp cloth. Rinse the area and repeat if necessary.

3) Vinegar wash and deodorize

• Combine equal parts white vinegar and water in a microwave-safe cup. Heat the cup in the microwave on high for 3–4 minutes to produce steam and dissolve grease.
• Wipe down the interior with a clean cloth, paying attention to corners and the door seal. Rinse with a little plain water and dry.

Clean the turntable, roller ring, and interior surfaces

Remove the turntable and roller ring and wash them with warm, soapy water. Rinse, dry completely, and reassemble. Wipe the interior ceiling and walls with a damp cloth, then dry to prevent streaks. If your glass turntable is heavily stained, a brief wipe with a gentle glass cleaner may help, but avoid leaving any cleaner on plastic or coated surfaces.

Post-cleaning deodorizing and prevention tips

• Run a short dry cycle or leave the door ajar for a few minutes to air out odors and dry the interior thoroughly.
• To minimize future grease buildup, cover foods with microwave-safe lids or splatter guards, wipe surfaces after cooking, and clean the microwave regularly rather than waiting for heavy buildup.

Tip: clean wooden utensils after cooking to prevent grease from transferring to dishes and countertops.

Maintenance tip: descale coffee machine regularly to prevent mineral buildup that could affect performance and flavor of beverages.

With consistent attention, heavy grease can be eliminated efficiently, preserving the microwave’s longevity and maintaining a fresh kitchen environment.
