Soak containers in vinegar and water
Soaking containers in vinegar and water is an effective way to eliminate unpleasant odours. Here is a step-by-step guide:
Step 1: Prepare the Vinegar and Water Solution
Mix equal parts white vinegar and water. For a stronger solution, use one cup of vinegar with a quarter cup of baking soda in a large bowl and then add water. Alternatively, for a smaller container, you can use one tablespoon of vinegar with a generous amount of baking soda and then add water.
Step 2: Soak the Container
Place the plastic container in the bowl and add water until the container is completely submerged. Ensure all surfaces are coated by shaking the container with the lid secured.
Step 3: Soaking Time
Let the container soak for at least a few hours. For more stubborn odours, it is recommended to soak for 1-2 days.
Step 4: Rinse and Wash
After soaking, thoroughly rinse the container with cold water to remove both the odour and the vinegar scent. You can add a teaspoon of baking soda to the rinse water to neutralise any lingering vinegar smell. Finally, wash the container in the dishwasher or with soapy water to complete the process.
This method is an easy and natural way to remove unpleasant smells from plastic containers, leaving them fresh and ready for reuse.

Use lemon juice to clean containers
Lemon juice is a great natural way to clean your plastic containers and remove lingering odours. The citric acid in lemon juice is a powerful odour eliminator, breaking down the compounds that cause bad smells. It will leave your plastic containers with a fresh, citrusy scent.
To use lemon juice to clean your containers, start by mixing the juice of one lemon with equal parts water. Toss in the squeezed lemon halves as well, to ensure you get the most out of the fruit. Let the solution soak in the container for a few hours. If you don't have lemon juice, you can also rub a cut lemon around the interior of the container, or scrub the container with a sponge and some lemon juice.
After letting the lemon juice solution soak, rinse the container thoroughly with water. If there is still a lingering vinegar scent, you can add a teaspoon of baking soda to the rinse water to neutralise it.
Lemon juice can also be used to clean other plastic items, such as bins. For a quick clean, simply pour some lemon juice into the item and scrub the surface with a rag or sponge. For a more intense clean, cut a lemon in half and rub the fruit over the plastic. After cleaning, rinse off any leftover lemon juice and let the plastic air out for several hours.

Use baking soda and water
Baking soda is a powerful natural deodorizer that can help eliminate food stains and neutralize odors. To use it, mix one tablespoon of baking soda with one cup of water to create an odor-fighting paste. You can adjust the ratio of baking soda to water to form a paste of your desired consistency. Spread the paste inside the container, focusing on any problem areas.
For more intense smells, you can soak the container in warm water with one to two tablespoons of baking soda overnight before washing. Simply fill the container with warm water and add a generous amount of baking soda, stirring to dissolve. Let the container soak for several hours or overnight, then rinse thoroughly with clean water.
Alternatively, you can sprinkle baking soda into the container and add a bit of water to make a paste. Gently massage the baking soda into the plastic with wet hands. Leave the paste to sit for a few hours or overnight, then rinse clean and wash with dish soap and water.
If you're looking to neutralize the lingering smell of vinegar, add a teaspoon of baking soda to the rinse water.

Use charcoal to absorb odours
Charcoal is a great natural deodorizer and can be used to effectively remove odours from plastic containers. It is important to use food-safe charcoal, and not the kind used for grilling. Place a piece of charcoal in the container, seal the lid, and let it sit for a few days. The charcoal will absorb the bad food smells and neutralize them, leaving your container fresh and ready to use.
If your container has a lid, seal it and let the charcoal sit indefinitely. Check on an hourly or daily basis to see if the smell has gone. If your container does not have a lid, you can place the charcoal in a glass dish or make a little cup out of foil to hold the charcoal. This method is especially effective for plastic containers with persistent smells.
It is worth noting that this method may take longer than 24 hours, so it is important to be patient and allow the charcoal to work. Charcoal is a great, natural way to remove odours from plastic containers without the use of harsh chemicals.

Store containers in a cool, dry place
To get the smell out of plastic containers, it is important to store them in a cool, dry, and well-ventilated area when not in use. Here are some detailed tips to ensure proper storage and maintain the freshness of your containers:
Firstly, always dry your containers completely before storing them. Moisture buildup can lead to the development of unpleasant odors and provide an ideal environment for bacteria, mold, or mildew, all of which contribute to musty smells. Therefore, ensure your containers are thoroughly dried before placing them in a storage area.
Secondly, choose a storage location that is cool and dry. Avoid areas with high heat and humidity, as these conditions can accelerate the growth of odor-causing bacteria and the development of musty smells. Opt for a well-ventilated space to promote air circulation, which helps prevent odors from settling in.
Additionally, it is recommended to occasionally open the containers and let them air out. This practice helps prevent odors from becoming entrenched in the plastic. Regularly inspect your containers to catch any odor issues early on. If you notice any smells, address them promptly using odor-fighting methods such as baking soda, vinegar, or charcoal treatments.
Another tip is to store pungent foods separately. Keep strong-smelling foods in dedicated containers or seal them in airtight, disposable plastic bags before placing them inside the plastic containers. This practice helps prevent the transfer of pungent odors to the plastic and maintains the freshness of your containers for longer.
Finally, pay attention to the condition of your containers. Plastic containers have a lifespan, and over time, they may develop scratches, cracks, chips, or discoloration, making them more susceptible to odor retention. If you notice any signs of wear and tear, consider replacing the containers. Additionally, if the lids become damaged or no longer fit tightly, it may be time for new containers.
