What You'll Learn

Use baking soda and water
If your plastic container has an unpleasant smell, baking soda and water can help eliminate it. Start by mixing one tablespoon of baking soda with one cup of water to create a thick paste. You can also add a bit of dish soap to the mixture. Generously apply the paste to the interior of the container, ensuring all surfaces are covered. Let the paste sit for at least an hour or preferably overnight. The baking soda will work its magic by absorbing and neutralizing odours.
After letting the paste sit, thoroughly wash the container with water and dish soap. If there are stubborn stains or odours, you can repeat the process. Alternatively, you can fill the container with warm water and add a generous amount of baking soda, stirring to dissolve. Let this mixture soak for several hours or overnight, then rinse thoroughly with clean water.
For extremely stubborn odours, you can try a more intensive method. Mix one cup of white vinegar with 1/4 cup of baking soda in a large bowl, being careful as this mixture will fizz. Place your plastic container in the bowl and add water until the container is submerged. Soak the container in this solution for one to two days. Finally, wash the container in the dishwasher or with soapy water to get rid of any lingering vinegar smell.
Always remember to dry your containers completely before storing them to prevent moisture buildup, which can lead to odours. Additionally, occasionally opening containers and letting them air out can help prevent odours from setting in. By following these simple steps, you can effectively use baking soda and water to remove even the toughest odours from your plastic containers.

Soak in lemon juice
Soaking in lemon juice is an effective way to remove odours from plastic containers. Lemon juice contains citric acid, which is a powerful odour neutralizer and eliminator. It also leaves behind a fresh, citrusy scent.
To start, squeeze the juice of one lemon into the container. Add an equal amount of water and toss in the squeezed lemon halves. Let the mixture soak for a few hours, then thoroughly rinse the container.
You can also scrub the inside of the container with a sponge soaked in lemon juice or rub the interior with a cut lemon slice. Lemon juice can help lighten any lingering food stains as well.
After soaking or scrubbing with lemon juice, wash the container with soap and water. Then, leave the container to dry in direct sunlight for one to two days. The sunlight will help break down any remaining odour-causing compounds.
Remember to always wash containers with soap and water immediately after use to prevent odours from building up. When cleaning, use a non-abrasive sponge or brush to avoid scratches that can trap food particles and odours.

Leave in direct sunlight
Sunlight is a natural odour eliminator, as it breaks down the compounds that cause unpleasant smells. Leaving a plastic container in direct sunlight is an effective way to remove unwanted odours.
First, ensure the container is washed and dried thoroughly. Then, place the container without its lid in direct sunlight for one to two days. Rotate the container occasionally to ensure even exposure to the sunlight. If you are unable to leave the container outdoors, you can place it on a windowsill, leaving the window open to let fresh air help eliminate the odours.
This method can also help lighten any food stains in the container. However, it is worth noting that some people express concern over potential UV radiation damage to the plastic, which may cause the release of molecules that are unsafe for ingesting.
Leaving plastic containers in direct sunlight is a simple and effective way to remove odours, but it may take some time, and there are other methods you can try in conjunction with sunlight exposure, such as using baking soda or vinegar.

Seal with newspaper
Plastic containers are a convenient choice for storing food, but they can retain strong food odours due to their porous nature. To remove these odours, crumple up some newspaper, seal it inside the container, and leave it overnight or longer. Then, wash the container thoroughly with soap and water.
Newspaper is effective at absorbing unpleasant odours lingering in plastic containers. This method is best used in combination with other techniques, such as washing the container with soap and water beforehand or leaving the container in direct sunlight for a few hours.
It is important to note that even clean containers can retain smells if they are stored before drying completely. Therefore, it is recommended to store containers in a cool, dry, and well-ventilated area when not in use, and to avoid heat and humidity, which can accelerate odour development.
Additionally, to prevent odours from setting in, it is advisable to occasionally open containers and let them air out. Dating stored food can also help track freshness and prevent spoilage, while regular inspections can help catch odour issues early on.
By following these simple steps, you can effectively remove odours from plastic containers and keep them fresh for longer.

Use charcoal
Charcoal is a great natural deodorizer and can be used to remove tough odours from plastic containers. It is important to use natural charcoal without any easy-light additives or mesquite.
To use charcoal to remove odours, place a piece of charcoal in the container and seal the lid. Leave the charcoal in the container for one to two days. The charcoal will absorb the bad food smells, leaving your container fresh.
You can also put the charcoal in a glass dish or shot glass inside the container or make a little cup out of foil to hold the charcoal. This method is especially useful if you do not want to wait for the container to be completely odour-free before using it again.
To prevent odours from building up in plastic containers, it is important to avoid heat and humidity, which can accelerate odour development. Store containers in a cool, dry, and well-ventilated area when not in use. Additionally, avoid microwaving food in plastic containers as it can cause the container to absorb more smells and stains.
By following these simple steps, you can effectively use charcoal to remove odours from plastic containers and keep them fresh for longer.
