What You'll Learn
Use vinegar and water to remove stains
Vinegar is a great natural, food-safe substance to use to remove stains from plastic containers. It is made from organic compounds and is eco-friendly and non-toxic. It can also help clear away hard water deposits from previous washings.
To remove stains from your plastic containers using vinegar, start by mixing equal parts white vinegar and warm water in a container. The mixture should be about one tablespoon of vinegar per cup of water. If you are dealing with tougher stains, you can use a little more vinegar, but be careful not to use too much, as it could damage the plastic.
Next, apply the mixture to the stained areas of the container. If the stain is on the bottom of the container, fill the container with about an inch of the mixture. If the stains reach up the sides, fill the container to the top. Place the lid on the container and leave it to soak for 30 minutes to 2 hours. The vinegar will break down any discolouration and neutralise odours.
After letting the mixture sit, pour it out and scrub the container with a sponge or cloth. You can also add a few drops of liquid dish detergent to help remove any remaining vinegar scent. Finally, rinse the container with clean water and let it dry.
For tougher stains, you can repeat the process or try using a baking soda paste.

Bleach as a stain removal solution
Bleach is a powerful cleaning agent that can be used to remove stains from plastic food containers. It is important to note that bleach should be used with caution as it can be harmful if ingested and can also damage certain types of plastics. When using bleach, always work in a well-ventilated area and avoid mixing it with other cleaning agents to prevent toxic chemical reactions.
To use bleach as a stain removal solution for plastic food containers, create a mild bleach solution by mixing one tablespoon of chlorine bleach with one cup of hot water. Ensure that the bleach is diluted sufficiently, as undiluted bleach can damage plastics. Always refer to the manufacturer's instructions for dilution ratios and safety precautions specific to the bleach product you are using.
Submerge the stained plastic container in the bleach solution and let it soak for at least one hour or up to overnight. The duration of soaking depends on the severity of the stain. For lighter stains, an hour may be sufficient, while deeper or older stains may require a longer soaking time.
After soaking, thoroughly rinse the container with hot water to remove any traces of bleach. It is crucial to ensure that all bleach residue is eliminated before using the container again. Wash the container with dish soap and hot water, scrubbing any remaining stained areas with a sponge or brush. Finally, allow the container to air dry before using it to store food items.
While bleach is effective for stain removal, it may not be suitable for all types of plastics or individuals sensitive to chemicals. In such cases, alternative stain removal methods using natural ingredients like baking soda, vinegar, lemon juice, or hand sanitizer can be explored. These methods may require more elbow grease but offer a gentler approach to whitening plastic food containers.

Baking soda paste for extra tough stains
To remove tough stains from plastic food containers, a baking soda paste is a great option. This method is especially useful for containers that have yellow stains.
To make the baking soda paste, start by pouring some baking soda into a small cup or container. Next, slowly add water and mix until the solution forms a paste. The paste should be thick but spreadable, similar to the consistency of toothpaste.
Once you have the desired consistency, apply the paste to the stained areas of the container. Use a sponge or paper towel to rub the paste into the plastic, pressing hard to ensure it gets inside the pores of the plastic. You can also use a sponge to scrub the paste onto the container in circular motions, as this will require some elbow grease.
Let the paste sit on the container for several hours or even overnight. For extra effectiveness, you can apply a second layer of paste after the first application has dried. This will prevent the paste from drying out too quickly and give it more time to remove the stains.
After the paste has had time to work, scrub the container with a sponge or rag to remove the paste. Then, rinse the container thoroughly with warm water to ensure all residue is removed.
If any stains remain, you can reapply the baking soda paste and repeat the process. Alternatively, you can try using a gentle abrasive with water to remove stubborn stains.
This method is a great way to remove tough stains from plastic food containers and restore them to their original appearance.

Soak in lemon juice and sunlight
To whiten plastic food containers using lemon juice and sunlight, start by cutting a lemon in half and rub the lemon on the stained area. Make sure to cover the stain with lemon juice. If the container has small nooks and crannies, spread the lemon juice into those areas.
After covering the stain, bring the container outside and place it in direct sunlight. Leave the container in the sun for a few hours to a whole day. The acid in the lemon combined with the sun's UV light will remove the discoloration and kill bacteria.
If the stain persists, leave the container in the sun for another day. For tougher stains, you can also try scrubbing the container with a mixture of lemon juice and salt using a damp cloth.
After the stain has been removed, rinse the container with warm water and dry it.

Rubbing alcohol or hand sanitiser
If you have a lot of extra hand sanitiser, this could be a great option for you. Firstly, check that your hand sanitiser is alcohol-based, as this is key to the method's success.
Pour or pump enough hand sanitiser onto the stained area of the container to completely cover it. Leave the sanitiser to sit for around 45 minutes to an hour. After this time, the stain should have lifted from the plastic and transferred onto the surface of the hand sanitiser. Pour the hand sanitiser down the drain, then wipe around the container with a slightly damp paper towel or soft cloth. Finally, wash the container with hot, soapy water and allow it to air dry.
This method is particularly effective for stains on the bottom of the container, as the hand sanitiser must cover the stain completely. It is also good for removing tomato-based stains.
