Plastic containers are convenient and practical solutions for food storage. However, they can sometimes emit less-than-pleasant odors. The reasons can vary: it might be the material itself or food remnants that left their mark. The smells from the food can be quite persistent. Fortunately, there are numerous ways to eliminate them. You can use liquid soap, vinegar, baking soda, and other absorbent substances. With a little effort, you can restore freshness to your containers. Keep reading to find out how.

Using Soap and Water

Step 1. Remove Food Residues.

Step 1

First, clear the container of any leftover food. If the odor is coming from the food, make sure to thoroughly remove all remnants. If you face difficulties, you can use a spatula or another tool. It’s also a good idea to pour warm water into the container to make the process easier.

  • Make sure to remove any grease and oil. Even after removing food remnants, there may still be a greasy film on the walls of the container. To remove it, use a paper towel to soak up any excess oil or grease.[1] X Source

Step 2. Soak the Container in Soap Solution.

Fill the sink or a large bowl with warm water and add dishwashing detergent, then soak the container. This will help get rid of the most stubborn odors. Leave it in the solution for about half an hour.

Step 3. Dry the Container.

Step 3

After soaking, take the container out and rinse it with clean water. Then, dry it with a cloth or paper towel. Now check if you’ve managed to eliminate the odor. EXPERT TIP: If the smell remains, sprinkle a little baking soda inside the container, leave it for a few minutes, and then wash it again.

Step 4. Place the Container in the Dishwasher.

Absorbing and Masking Odors
