how to deep clean microwave

To deep clean a microwave safely and effectively, use steam plus a gentle cleaner like baking soda, vinegar, or dish soap, then wipe all surfaces and removable parts thoroughly. This method loosens baked-on splatters, removes odors, and is recommended by major appliance and cleaning brands.

Quick Scoop

  • Use steam (water with baking soda, vinegar, or lemon) to loosen gunk.
  • Wash the turntable and any racks in hot, soapy water like regular dishes.
  • Wipe inside, door, and exterior controls with a damp cloth and mild cleaner, not harsh abrasives.

Step-by-step deep clean

  1. Prep and unplug (if easy)
    • Unplug the microwave or at least be sure the cord and plug stay dry for safety.
 * Remove the glass turntable and roller ring so you can reach all the corners.
  1. Steam to loosen grime
    • In a microwave-safe bowl, mix about 1 cup of water with either 1–2 tablespoons baking soda, a few tablespoons white vinegar, or lemon slices with their juice.
 * Microwave on high until it boils and the window steams up (about 3–5 minutes), then keep the door closed for another 5–10 minutes so the steam can soften dried splatters.
  1. Wipe the interior
    • Carefully remove the hot bowl, then use a soft cloth or sponge to wipe the ceiling, walls, floor, and around the door opening.
 * For stubborn spots, dip your cloth in the warm baking-soda or soapy water and rub gently instead of using steel wool or anything scratchy.
  1. Clean the turntable and parts
    • Wash the glass plate, roller ring, and any rack in hot water with dish soap; treat them like regular dishes.
 * Rinse and dry fully before putting them back so you don’t trap moisture under the plate.
  1. Door, exterior, and vents
    • Wipe the inside and outside of the door with a mild all-purpose cleaner or soapy water, focusing on edges and the door seal where grease builds up.
 * Spray cleaner onto the cloth, not directly on vents or electronic controls, to avoid pushing liquid into openings.

Extra-deep tips and odors

  • Really baked-on mess
    • Repeat the steam step, then make a paste of baking soda and a little water and apply it to stuck-on areas for a few minutes before gently scrubbing.
  • Bad smells
    • Run a cycle with water, vinegar, and lemon slices, then wipe dry to help neutralize lingering odors.
  • Grease-heavy microwaves (over range)
    • If your model has a removable filter, many manufacturers recommend soaking it in warm soapy water, sometimes with added baking soda, then rinsing and drying before reinstalling.

Keeping it clean longer

  • Cover food with a microwave-safe cover, plate, or paper towel to prevent splatter.
  • Wipe small spills as soon as the interior cools instead of letting them bake on through multiple uses.
  • Do a quick steam-and-wipe once a week if you use the microwave daily; this keeps deep cleans much easier.
