How to Remove Smell from Food Containers

Why Food Containers Develop Persistent Odors

Plastic food containers absorb food odors at a molecular level — especially from garlic, onions, fish, curry, and fermented foods. Even after washing, these odors can linger for weeks. Glass and stainless steel containers are far less prone to odor absorption, but can still develop smells from the lid seals.

What You'll Need

• Baking soda
• White vinegar
• Dawn Platinum Dish Soap
• Cup lid gap cleaning brush set
• Newspaper or activated charcoal (optional)

Method 1: Baking Soda Soak (Best for Most Odors)

1. Add 2 tablespoons of baking soda to the container
2. Fill with warm water and stir to dissolve
3. Let soak for 30 minutes to several hours for strong odors
4. Wash with dish soap and rinse thoroughly
5. Air dry with the lid off

Method 2: White Vinegar Soak

1. Fill the container with equal parts white vinegar and warm water
2. Let soak 30 minutes
3. Wash with dish soap and rinse thoroughly — the vinegar smell dissipates as it dries

Method 3: Baking Soda Dry Absorption (For Stubborn Odors)

1. Wash and dry the container completely
2. Place 2–3 tablespoons of dry baking soda inside
3. Close the lid and leave overnight or for 24–48 hours
4. Discard the baking soda and wash normally

Dry baking soda absorbs odor molecules from the plastic surface over time — more effective than a quick soak for deeply embedded smells.

Method 4: Newspaper Trick

Crumple newspaper and stuff it inside the clean, dry container. Close the lid and leave overnight. Newspaper absorbs odors effectively. Discard and wash normally.

Don't Forget the Lid Seal

The rubber or silicone seal in the lid traps odors just as much as the container body. Remove the seal if possible and soak separately in vinegar solution. Use a lid gap brush to scrub the seal groove thoroughly.

Preventing Food Container Odors

• Rinse immediately after use — don't let food sit
• Store with the lid off when empty — airflow prevents odor buildup
• Use glass containers for strongly scented foods like garlic, fish, and curry
• Wash promptly — the longer food sits, the deeper odors penetrate

Final Thoughts

Baking soda — either as a soak or dry overnight treatment — is the most effective odor eliminator for food containers. Always clean the lid seal with a gap brush and store empty containers with the lid off to prevent odors from returning.
