Your food storage containers smell because plastic absorbs odours from strong foods like garlic, curry and fish, and because trapped moisture and food residue can grow bacteria. To remove the smell, wash thoroughly, then deodorise with a baking soda paste, a vinegar soak, or by leaving the clean container in sunlight. Drying containers fully and storing them with lids off also prevents smells. This guide explains why containers smell and how to fix it.
Plastic absorbs odours from strong foods, and trapped moisture and residue cause smells. Wash well, then deodorise with a baking soda paste, a vinegar soak, or sunlight. Dry fully and store with lids off to prevent it.
Why Containers Smell
- Plastic absorbs odours: strong foods like garlic, curry and fish soak smells into plastic.
- Trapped moisture: sealing damp containers grows bacteria and musty smells.
- Food residue: bits left in seals and corners decompose and smell.
- Old or scratched plastic: holds odours more.
Key Takeaway: Smells live in the lid seal and the plastic itself. Scrub the gasket and corners where residue hides, deodorise the plastic with baking soda or sun, and store lids off so trapped moisture cannot turn musty.
How to Remove Container Smells
- Wash thoroughly, including the lid seal and corners.
- Rub a baking soda paste inside and leave for a few hours, then rinse.
- Or soak in equal parts warm water and vinegar, then wash.
- Leave the clean container in sunlight, which deodorises and disinfects.
- Dry completely before storing.
Preventing Smells
- Dry containers fully before sealing or storing.
- Store containers with lids off so air circulates.
- Rinse strong-smelling foods out promptly.
- Use glass for very strong foods. See glass vs plastic food storage.
When to Replace
If a plastic container holds smells despite cleaning, or is scratched and cloudy, replace it. See best plastic food storage containers.
