What You'll Learn
Using vinegar and water
Vinegar is an excellent natural alternative to cleaning stains from plastic containers. Its acidic properties break down stain particles. White vinegar is the best option, as other types may leave their own stains or discolourations.
To make a vinegar and water solution, mix equal parts vinegar and water. For example, mix one cup of hot water with one tablespoon of vinegar. You can also use a ratio of one tablespoon of vinegar per cup of water. Pour the solution into the stained container and let it soak for two to three hours. If the stain is particularly stubborn, you can increase the vinegar concentration to 30% cleaning vinegar.
After soaking, drain the vinegar solution, then wash and dry the container. The vinegar smell will disappear once the container is dry. This method is eco-friendly and non-toxic, making it perfect for cleaning food containers.
If the stain persists, you can repeat the process or try making a baking soda paste. Sprinkle baking soda into the container, then add water to form a paste. Spread the paste over the stained areas and let it sit for 30 minutes. After 30 minutes, wipe the paste with a damp cloth, then rinse with dish soap and warm water.

Baking soda paste
Baking soda is a great natural ingredient for cleaning plastic containers. It can be used to clean and remove stains and lingering scents from plastic containers.
To make a baking soda paste, sprinkle a thick layer of baking soda on the bottom of the container. Next, sprinkle water over the baking soda to form a thick paste. The paste should be just a tiny bit thinner than toothpaste; you want it to spread easily but not be runny.
Once the paste is ready, smear it all over the stained areas of the container. Let the paste sit for 30 minutes. After 30 minutes, wipe the paste around with a damp cloth, rubbing the bottom well, then rinse with dish soap and warm water.
If the stain is still visible after 30 minutes, give it another 30 minutes. Once the stain is gone, wash out the baking soda residue and allow the container to dry.
Baking soda can also be used in conjunction with vinegar to remove stains.

Bleach
When using bleach, it is important to wear rubber gloves and mix it with water before applying it to your containers. The general ratio is one tablespoon of bleach to one cup of water, but this can be adjusted depending on the severity of the stain. Mix the liquids lightly with a whisk or by shaking the container gently.
Once the solution is ready, pour it into the stained container until the stain is covered. You can then close the lid and gently shake the container to ensure the solution comes into contact with the stain. Allow the container to sit for at least an hour, or even overnight if necessary.
After the bleach solution has had time to work, thoroughly wash the container with hot, soapy water and allow it to air dry. It is important to ensure that all traces of bleach are removed, so continue washing until you can no longer detect the smell of bleach. You may also want to run the container through the dishwasher to ensure it is completely clean.
By following these steps, you can effectively use bleach to remove food residue and stains from your plastic containers. Just remember to always exercise caution when working with bleach and to thoroughly wash the containers afterwards.

Lemon juice and sunlight
It is important to note that while this method is effective for removing stains, it may not be sufficient for removing odors. To address odors in plastic containers, it is recommended to wash the containers with soap and water after each use and ensure they are completely dry before storing. Additionally, it is suggested to store the containers in a well-ventilated area and use tight-fitting lids to prevent the development of unpleasant smells.
Lemon juice has been known to have a dissolving effect on some plastics. While the impact may be negligible, it is important to be cautious when using lemon juice to clean plastic containers. It is recommended to thoroughly rinse the containers with water after treating them with lemon juice to avoid any potential negative effects.
Combining lemon juice with sunlight is a great organic way to remove stains from plastic containers without the use of harsh chemicals. This method may require some patience, as the process can take a couple of days to fully work. However, it is a hands-off approach that allows the sun to naturally do the work of removing discoloration and eliminating lingering scents.

One option is to use baking soda, which can be applied as a paste or sprinkled over the stain, and then rinsed with water after 20-30 minutes. Another option is to use vinegar, which can be applied directly to the stain or mixed with water, and then rinsed off after a few minutes.
