How To Get Smells Out of a Microwave

Microwaves can trap lingering odors from various foods, making your kitchen less pleasant. Whether it’s the smell of burnt popcorn, spicy foods, or other strong odors, restoring your microwave to its fresh state is simple with these proven methods.


Why Do Microwaves Retain Odors?

  1. Food Residues: Grease and food particles left behind can emit unpleasant smells over time.
  2. Steam Absorption: Microwaves absorb strong food odors through steam, which can cling to the interior walls.
  3. Burnt Food: Residue from burnt foods can leave persistent odors.

Step-by-Step Methods to Remove Microwave Smells

1. Steam Cleaning with Vinegar

Vinegar is a natural deodorizer that helps break down grease and neutralize odors.

  • Steps:
    1. Fill a microwave-safe bowl with one cup of water and two tablespoons of white vinegar.
    2. Place the bowl in the microwave and heat on high for 3–5 minutes.
    3. Leave the door closed for an additional 5 minutes to allow the steam to loosen residue.
    4. Wipe down the interior with a damp cloth or sponge.

2. Lemon Steam Freshener

Lemon is excellent for cutting through grease and leaving a fresh citrus scent.

  • Steps:
    1. Slice a lemon in half and squeeze the juice into a microwave-safe bowl of water.
    2. Place the lemon halves in the bowl as well.
    3. Heat on high for 3–5 minutes, then let it sit for another 5 minutes.
    4. Wipe the interior clean with a soft cloth.

3. Baking Soda Solution

Baking soda is an effective odor absorber.

  • Steps:
    1. Mix two tablespoons of baking soda with one cup of water in a microwave-safe bowl.
    2. Heat the mixture in the microwave for 3–5 minutes.
    3. Let the microwave cool slightly, then wipe it clean.
  • Alternative: Leave an open container of baking soda inside the microwave overnight to absorb lingering odors.

4. Coffee Grounds

Coffee has strong deodorizing properties and can replace bad smells with a rich aroma.

  • Steps:
    1. Place damp coffee grounds in a microwave-safe container.
    2. Heat on high for 2–3 minutes.
    3. Leave the container in the microwave for 1 hour before wiping it down.

5. Charcoal or Activated Carbon

Activated charcoal is a powerful odor absorber that works without heat.

  • Steps:
    1. Place a small bowl of activated charcoal or charcoal briquettes in the microwave.
    2. Leave it overnight to absorb odors naturally.

6. Vanilla Extract

Vanilla not only neutralizes odors but also leaves a pleasant scent.

  • Steps:
    1. Mix one tablespoon of vanilla extract with one cup of water in a microwave-safe bowl.
    2. Heat on high for 2–3 minutes.
    3. Wipe down the interior with a clean cloth.

Cleaning the Microwave for Persistent Odors

1. Remove and Clean the Turntable

  • Take out the turntable and wash it with warm, soapy water.
  • Dry it thoroughly before placing it back.

2. Scrub the Interior

  • Use a mixture of dish soap and warm water to scrub the walls and ceiling of the microwave.
  • Pay attention to corners where residue can accumulate.

3. Check the Vents

  • Inspect the microwave vents for trapped grease or food particles. Clean them gently with a damp cloth.

Preventing Odors in the Future

  1. Cover Food: Always use a microwave-safe cover to prevent splatters and odors.
  2. Clean Regularly: Wipe down the interior after each use to remove food particles and spills.
  3. Use Baking Soda: Keep an open container of baking soda in the microwave when it’s not in use to absorb smells.
  4. Ventilation: After using the microwave, leave the door open for a few minutes to let residual steam escape.

When to Replace the Microwave

If odors persist despite thorough cleaning, it could indicate that the smell has permeated the interior components. In such cases, replacing the microwave might be the best option.


By following these tips, you can quickly and effectively eliminate odors from your microwave, ensuring it stays fresh and functional for daily use.
