How to Remove Fish Smell from Microwave: A Simple and Effective Guide


Microwaves are essential kitchen appliances that make cooking and reheating food quick and convenient. However, using them to cook fish can leave a strong and unpleasant odor that lingers inside the microwave. If you’ve ever experienced this, you know how challenging it can be to get rid of the fish smell. But worry not! In this article, we’ll provide you with some easy and effective methods to eliminate fish odor from your microwave, leaving it smelling fresh and clean.

Understanding the Fish Odor

Before diving into the solutions, it’s essential to understand why fish odor tends to cling to microwave interiors. When fish is heated in the microwave, its volatile compounds, including trimethylamine, are released as gas. These compounds are responsible for the characteristic fishy smell. The steam and fumes from cooking fish can permeate the microwave’s interior, leaving behind an unpleasant odor that can be quite persistent.

Cleaning with Natural Agents

1. Lemon and Water

Lemons are known for their natural deodorizing properties, making them a perfect solution for eliminating fish smells. Cut a fresh lemon in half and squeeze the juice into a microwave-safe bowl filled with water. Place the bowl inside the microwave and run it on high power for two to three minutes. The steam generated by the lemon-water mixture will help neutralize the fish odor, leaving behind a refreshing citrus scent.

2. Vinegar Solution

White vinegar is another excellent natural deodorizer that can tackle fish odors effectively. In a microwave-safe bowl, mix equal parts of white vinegar and water. Heat the solution in the microwave for three to five minutes on high power. The acidic nature of vinegar helps break down the fish odor molecules, leaving your microwave smelling fresh.

Cleaning with Baking Soda

Baking soda is a versatile and natural odor absorber. It can effectively eliminate strong smells, including fish odor, from your microwave.

3. Baking Soda Paste

Create a thick paste by mixing baking soda with water. Apply the paste to the interior surfaces of the microwave, focusing on areas with the most noticeable odor. Let it sit for about 30 minutes to allow the baking soda to absorb the odors. Then, wipe off the paste with a damp cloth or sponge.

4. Baking Soda and Vinegar

For a powerful odor-fighting combination, sprinkle some baking soda on a microwave-safe plate and add a small dish of vinegar beside it. Place them both inside the microwave and heat on high power for two minutes. The chemical reaction between the baking soda and vinegar will release carbon dioxide and effectively neutralize the fish odor.

Prevention Tips

5. Covering Food

To prevent fish odor from permeating your microwave in the first place, cover the fish with a microwave-safe lid or a microwave-safe cover while cooking. This will help trap the odors and prevent them from spreading throughout the microwave.

6. Ventilation

Ensure proper ventilation in your kitchen while cooking fish in the microwave. Open a window or turn on the exhaust fan to allow the odors to dissipate quickly.

7. Cleaning Spills Promptly

Clean up any spills or splatters in the microwave as soon as possible, especially after cooking fish. Prompt cleaning will prevent the odors from settling and becoming challenging to remove later.


Microwaves are incredibly convenient appliances, but dealing with lingering fish odors can be bothersome. By using natural agents like lemon, vinegar, and baking soda, you can easily and effectively remove fish smells from your microwave. Additionally, implementing prevention tips will help you avoid the problem in the future, keeping your microwave fresh and odor-free.

Now you can enjoy cooking fish dishes without worrying about the persistent smell! Follow the simple steps mentioned in this guide, and your microwave will be ready for the next delicious meal.
