Plastic containers are incredibly convenient for storing food, but they also can harbor bad smells. Whether it be the plastic-y smell of the container itself or the odors of the food of days past, smells can ingrain themselves in the container and be quite stubborn. Try hand washing, cleaning using vinegar and baking soda, or absorbing the smell with various absorbing agents. With some effort, your container will be odor-free and ready to use!

Use vinegar and baking soda.

  1. Take a large bowl or pot, and pour in a cup of white vinegar before adding in ¼ cup of baking soda (52.2 g). Stir the baking soda into the vinegar until they are mixed. Then, drop the plastic containers into the bowl with the vinegar and baking soda, remembering to also add the lids. Add enough water to submerge the containers, stir the mixture in the bowl, and let the containers soak for 24-48 hours. [1]
    • Put the plastic container in the dishwasher afterward, since vinegar can leave behind a strong scent itself. If you don't have a dishwasher, scrub thoroughly using water and dishwashing detergent.

    Just do it with soap and water. Do not use acidic products on a regular basis, as they can eat away of plastic over time.

    Take some good dish soap and hand wash it. If that doesn't work, then put the water bottle in the freezer open, with no water in it.

      Tips

      • If smelly plastic containers are a recurring problem, consider investing in glass containers. Though it's more fragile, glass does not absorb odors or stain like plastic does. It also does not come with an unpleasant plastic-y smell. [7]
      • In general, the cheaper or softer the plastic, the more likely it will smell bad. If you can, always try to sniff the plastic container before purchasing to see if it has a plastic-y odor.
      • Avoid microwaving food in plastic containers. This can ingrain food odors into the plastic.
