Plastic containers are convenient for storing food, but they can also retain odours due to their porosity. To eliminate musty smells, it is essential to clean the containers thoroughly and address any residual food particles or moisture that may be causing the odour. While soap and water are typically used for cleaning, stronger methods may be required for stubborn odours. For example, creating a paste with baking soda and water and applying it to the container can help absorb lingering food smells. Similarly, crumpled newspaper, charcoal, and salt are known to absorb unpleasant odours. For a fresh scent, lemon juice or vanilla extract can be utilised. Alternatively, a mixture of vinegar and baking soda can be used, followed by a thorough rinse. Proper ventilation and direct sunlight are also effective in breaking down odour-causing molecules.

Exposing to sunlight
Sunlight is a natural disinfectant and deodorizer. It can effectively eliminate unpleasant odours from plastic containers without the use of harsh chemicals. Here is a guide on how to use sunlight to get rid of musty smells in your plastic containers:
First, ensure your plastic container is clean and dry. Wash the container with soap and hot water to remove any residual food particles or stains. Rinse it thoroughly and dry it completely before proceeding to the next step.
Next, place the clean and dry container in an area that receives direct sunlight. If possible, place it outdoors in direct sunlight. If you don't have access to an outdoor space, you can place it on a windowsill that receives ample sunlight. Make sure the container is open to maximize exposure to sunlight. Remove the lid or open any compartments to ensure that the sunlight reaches all the inner surfaces.
Leave the container in direct sunlight for at least a few hours. The duration may vary depending on the intensity of the sunlight and the severity of the odour. In some cases, it may be necessary to leave the container in the sun for a full day or two. If you are placing the container outdoors, you can leave it open to the fresh air, which will also help eliminate odours.
It is important to rotate the container periodically to ensure that all sides are exposed evenly to the sunlight. This will ensure that all odour-causing molecules are broken down effectively. If there are areas of the container that are shaded or blocked from direct sunlight, make sure to reposition the container to ensure complete exposure.
Finally, after exposing the container to sunlight, bring it back indoors and wash it again with mild soap and water. Rinse it thoroughly and dry it completely before using it to store food items. Exposing your plastic containers to sunlight is a simple, natural, and effective way to eliminate musty smells and keep them fresh and odour-free.

Using lemon juice
Lemon juice is a great natural deodorizer for plastic containers. The citric acid in lemon juice is a powerful odour neutralizer and will leave your plastic containers with a fresh, citrusy scent.
To use lemon juice to get rid of that musty smell, start by giving your container a good scrub with soap and warm water. Then, pour some lemon juice into the container and use a cloth or sponge to scrub the juice all over the interior surface. You can also cut a lemon and rub the lemon slice around the inside of the container for the same effect. Leave the lemon juice to work its magic for a few hours or overnight. If there is a particularly strong odour, you may need to leave the lemon juice for a few days. Wash the container with warm water and soap the next day, and your container should be odour-free.
Lemon juice can also help to lighten any lingering food stains. If you don't have lemon juice, you can also leave a freshly cut lemon inside the container, seal it, and let it sit overnight. The lemon will help to absorb the bad smells and leave your container smelling fresh.
You can also use lemon juice in combination with other natural deodorizers. For example, you can add a few drops of vanilla extract to the lemon juice before scrubbing. The powerful scent of vanilla will help to mask bad odours. Just be sure to rinse the container thoroughly with water after letting the mixture sit for a few hours.

Using charcoal
Charcoal is a great way to get rid of musty smells in plastic containers. It is a natural odour absorber and can be used to eliminate odours without the use of harsh chemicals. Here is a step-by-step guide to using charcoal to freshen up your plastic containers:
Step 1:
Start by giving your container a good scrub with soap and hot water. This will help to remove any residual food particles or stains that may be contributing to the odour. Make sure to dry the container completely before moving on to the next step.
Step 2:
Take a piece of charcoal and place it in your plastic container. It is important to use plain charcoal without any mesquite or easy-light properties. If you have leftover charcoal from a BBQ, that should work well.
Step 3:
Seal the container with the lid tightly closed. The container needs to be airtight for this method to work effectively.
Step 4:
Let the charcoal sit in the sealed container for at least 24 hours. The charcoal will work its magic and absorb the unpleasant odours from the plastic. The longer you leave it, the more effective it will be, so you can even leave it for up to 48 hours if needed.
Step 5:
After the charcoal has had enough time to absorb the odours, remove it from the container. Give your container a quick wash with dish soap and water to remove any residual charcoal dust or odours.
Additional Tips:
- If you don't have a full piece of charcoal, you can place the charcoal in a glass dish or shot glass inside the container.
- Make sure to use this method in a well-ventilated area, as the odours will be released into the air during the process.
- Charcoal is a natural and non-toxic odour absorber, making it a safe and effective choice for eliminating musty smells from plastic containers.
By following these steps, you can effectively use charcoal to get rid of musty smells and leave your plastic containers fresh and ready to use again.

Using salt
If your plastic container has an unpleasant musty smell, you can use salt to get rid of it. Here's how to do it:
First, rinse out any larger pieces of food or residue from the container. Then, fill the container with warm water and add a generous amount of salt. You can also add a tablespoon of baking soda to enhance the odour-fighting properties of the solution. Seal the container with its lid and let it soak for a few hours or even overnight. The salt and baking soda will work to absorb and neutralize the unpleasant odours.
After the soaking period, pour out the salty water and rinse the container thoroughly with clean water. If the smell still lingers, repeat the process, allowing the container to soak for a longer period. You can also try sprinkling baking soda over the damp container and letting it sit for a few minutes before rinsing again. This will provide an extra odour-fighting boost.
Additionally, sunlight is a great natural deodorizer. After rinsing the container, leave it open in direct sunlight for a day or two. Rotate the container periodically to ensure all sides receive direct sunlight. The UV rays will help break down any remaining odour-causing molecules.
As a preventative measure, always ensure your plastic containers are properly cleaned and thoroughly dried before storing them. Residual food particles and moisture can lead to the development of unpleasant odours. You can also store your containers with a pinch of salt or baking soda inside to help absorb any lingering smells.
By following these simple steps, you can effectively use salt to eliminate musty smells from your plastic containers and keep them fresh and odour-free.

Plastic containers can develop a musty smell if they are not cleaned or stored correctly. If the containers are not cleaned properly, residual food particles can release odors. If they are stored away before they are completely dry, moisture can accumulate, creating an environment for mold and mildew to grow.
To prevent musty smells from developing in your plastic containers, wash them with soap and water after every use and ensure they are completely dry before storing anything new inside. You can also store strong-smelling food items separately and seal them in airtight bags before placing them in the containers.
