5 Easy Ways to Get Burnt Popcorn Smell Out of Your Microwave

How to Get Burnt Popcorn Smell Out of Your Microwave? To get burnt popcorn smell out of your microwave, try steaming a mixture of vinegar and water or lemon juice and water for 3-5 minutes. You can also use baking soda to absorb odors, or place coffee grounds or activated charcoal inside the microwave overnight. Wipe down the interior afterward for best results.

In this guide, we’ll walk you through some tried-and-true ways to eliminate burnt popcorn odors, using common household items and easy-to-follow techniques.

Why Burnt Popcorn Smells Linger in the Microwave

The smell of burnt popcorn can linger in your microwave for hours or even days, and that’s because of how odors interact with the microwave’s surfaces. The combination of burnt oils, moisture, and food particles creates a perfect storm for persistent odors. Here’s why the smell sticks:

Residue and Moisture

When popcorn is overcooked, especially with the butter or oil that’s often added, it can leave behind residual oils in the microwave. These oils can cling to the microwave walls, turntable, and ventilation areas, which makes the smell stick around longer.

Popcorn kernels also contain moisture that gets released during the popping process. When exposed to heat, this moisture turns into steam and can cause the smell to spread and cling to the inside of the microwave.

Burnt Particles

If popcorn is overcooked, burnt particles can get lodged in small crevices in the microwave, like around the door seal or in the waveguide cover. These particles continue to release odor long after the popcorn is gone.

This combination of burnt oils, moisture, and food particles is the primary reason why burnt popcorn smells can be so difficult to remove.

5 Methods to Get Burnt Popcorn Smell Out of Your Microwave

Now that we understand why burnt popcorn smells linger, let’s explore the most effective methods to eliminate these odors and freshen up your microwave. These methods use common household items that are both natural and effective in deodorizing.

Vinegar and Water Steam

One of the most effective ways to remove burnt popcorn smells is by using a vinegar and water steam solution. The acidity of vinegar helps neutralize odors, while the steam works to loosen any residue inside the microwave.

How to use:

  1. Combine 1 cup of water and 1 cup of white vinegar in a microwave-safe bowl.
  2. Place the bowl in the microwave and heat on high for 3-5 minutes, until the solution boils and creates steam.
  3. Keep the door closed for about 15 minutes to allow the steam to fill the microwave, breaking down odor-causing particles.
  4. Carefully remove the bowl and wipe down the microwave interior with a clean cloth.

Why it works: Vinegar is a natural odor neutralizer and steam helps to break down grime and odors from burnt popcorn.

 

Lemon Steam Cleaning

Lemon offers a natural, refreshing scent while also acting as an effective deodorizer due to its acidity. This method works similarly to vinegar but provides a fresh citrus fragrance.

How to use:

  2. Place the bowl in the microwave and heat for 3-5 minutes until steam begins to form.
  3. Let the microwave sit for about 15 minutes to allow the steam to neutralize the burnt popcorn smell.
  4. Remove the bowl and wipe the microwave clean with a cloth.

Why it works: Lemon’s fresh scent helps mask odors, while its natural acidity breaks down odor-causing substances.

Baking Soda Absorption

Baking soda is one of the best natural odor absorbers, making it perfect for removing stubborn smells from your microwave. By simply placing a bowl of baking soda inside the microwave, you can absorb the remaining burnt odor.

How to use:

  1. Place an open box or a shallow bowl of baking soda inside the microwave.
  2. Leave it overnight, allowing the baking soda to absorb lingering odors.
  3. In the morning, remove the baking soda and clean any remaining residue.

Why it works: Baking soda’s absorbent properties neutralize and trap odors, helping to refresh your microwave.

 

Coffee Grounds as a Natural Deodorizer

Coffee grounds are known for their strong ability to mask and absorb odors. The scent of coffee also helps to freshen up your microwave while eliminating the burnt popcorn smell.

How to use:

  1. Place fresh coffee grounds in a bowl.
  2. Put the bowl in the microwave and leave it overnight to absorb odors.
  3. Discard the coffee grounds the next day.

Why it works: Coffee grounds are an excellent deodorizer, absorbing persistent odors and leaving a pleasant scent behind.

 

Activated Charcoal for Persistent Smells

Activated charcoal is a powerful deodorizer used to absorb and neutralize strong odors. This method is particularly effective if the burnt popcorn smell is persistent or if the microwave hasn’t been cleaned in a while.

How to use:

  1. Place a container of activated charcoal inside the microwave.
  2. Leave it in for 12-24 hours to absorb the odors.
  3. Remove the charcoal and clean any remaining surfaces if necessary.

Why it works: Activated charcoal has high absorbent properties, making it highly effective for eliminating even the strongest odors.

Preventing Future Burnt Popcorn Smells

Once you've successfully removed the burnt popcorn smell from your microwave, it’s important to take steps to prevent the odor from coming back. Here are some tips to help you avoid future burnt popcorn smells and keep your microwave smelling fresh.

Regular Cleaning

To keep your microwave in top shape, make it a habit to clean the interior regularly. Cleaning the microwave every 1–2 weeks can help remove any buildup of oil, food particles, or residue that can contribute to lingering smells. Wipe down the microwave with a damp cloth after each use, paying special attention to areas like the turntable, walls, and door seal.

Use Microwave Covers

Prevent food splatters and spills by using a microwave-safe cover when cooking popcorn or other foods. Covers help to contain moisture, steam, and food particles, reducing the likelihood of odors forming. If you frequently cook popcorn, consider using a microwave-safe bowl with a lid to keep the process mess-free.

Ventilation is Key

After each use, leave the microwave door open for a few minutes to allow moisture and steam to escape. This helps reduce any potential buildup of odors. Proper airflow allows the microwave to dry out and prevents moisture from getting trapped, which can contribute to smell.

Store Popcorn Properly

If you store popcorn in your microwave for later use (such as bags of pre-popped popcorn), make sure they are sealed tightly in an airtight container. Exposure to air and moisture can make the popcorn stale, which will lead to odors. Keeping your popcorn sealed helps maintain its freshness and prevents unnecessary odors from accumulating.

Regular Maintenance

Ensure your microwave is ventilated properly, and check that the turntable is moving freely. Periodic maintenance, such as cleaning the fan or the vent filter (if applicable), helps keep the microwave in good working order and prevents any odor buildup caused by neglected areas.

By following these simple tips, you can avoid having your microwave fill with the unpleasant scent of burnt popcorn in the future.

Cleaning the Microwave Turntable and Interior

After dealing with burnt popcorn odors, it's important to thoroughly clean the microwave’s interior, including the turntable, to prevent any lingering smells and ensure your microwave remains hygienic. Here's how to clean the turntable and the microwave's interior effectively.

Cleaning the Turntable

  • Remove the Turntable: Carefully remove the turntable from the microwave. Most turntables are made of glass, making them easy to clean.
