Learn why your reusable storage bag develops odors and how to deodorize it with simple cleaning methods. Keep your bags fresh and long-lasting.
Quick answer
Odors in reusable storage bags usually come from trapped food oils or bacteria. A simple baking soda soak or vinegar rinse can deodorize them, but avoid harsh scrubbing that damages the seal.
Why odors cling to reusable bags
Reusable storage bags are made from materials like PEVA or silicone, which are non-porous but can still absorb strong-smelling food compounds—especially oils from garlic, onions, or tomato sauce. If not cleaned promptly, these residues can cause persistent smells.
Another common cause is moisture trapped in the zipper seal. Even a small amount of water left after washing can create a breeding ground for mold or mildew, leading to a musty odor.
Material matters: PEVA vs silicone
PEVA bags, like the Ello Reusable Gallon Storage Bags, are lightweight and less prone to absorbing odors than silicone, but they still need proper drying. Silicone bags are more heat-resistant and can be boiled for deep cleaning, but they tend to retain smells from fatty foods. Knowing your bag's material helps you choose the right deodorizing method.
Diagnosis and fix steps
- Symptom: A strong food smell (garlic, onion, tomato) lingers even after washing with soap and water. If the smell is mild, a quick rinse may be enough; if strong, proceed to the cause step.
- Likely cause: Residual food oils or trapped moisture in the zipper seal. Oils can cling to the material even after a normal wash. Check the seal area for visible residue or moisture before moving to corrective action.
- Corrective action: Fill the bag with a mixture of warm water and baking soda (1 tablespoon per cup) or equal parts water and white vinegar. Let it soak for 15-30 minutes, then scrub gently with a soft sponge. Rinse thoroughly and air dry completely with the zipper open. For stubborn odors, repeat the soak or add a few drops of lemon juice. Do not use bleach or abrasive cleaners.
- Stop or choose another option: If the smell persists after two deep-cleaning attempts, the bag may have a compromised seal or mold inside the zipper track. At this point, replace the bag to ensure food safety. Inspect the zipper for black spots or warping. If damaged, recycle the bag and start fresh.
Product fact
- Reusable Gallon Storage Bags, Set of 2: Made from food-grade PEVA material. One bag displaces up to 300 plastic baggies. PEVA is less absorbent than silicone, so odors are easier to remove with a simple baking soda soak.
