Bleach solutions
- Prepare the Bleach Solution: In a large container, mix one tablespoon of chlorine bleach with one cup of hot water. Ensure you are in a well-ventilated area when handling bleach.
- Soak the Stained Container: Submerge the stained plastic container in the bleach solution. If the container is too large to submerge, use a sponge or damp cloth to apply the solution to the stained area.
- Let it Sit: Allow the container to soak in the solution for at least one hour or up to overnight. This will give the bleach solution time to break down the tough stains.
- Rinse and Wash: After soaking, remove the container from the bleach solution and thoroughly rinse it with water. Wash the container with hot, soapy water to ensure all traces of bleach are removed.
- Air Dry: Once rinsed and washed, let the container air dry completely.
It is important to note that you should not expose bleached plastic containers to direct sunlight immediately after cleaning, as this may enhance discolouration. Additionally, always protect your hands and eyes when working with bleach, and never mix bleach with other cleaning agents to avoid dangerous chemical reactions.
For an alternative to chlorine bleach, you can use lemon juice and sunlight. The acid in lemon juice acts as a natural bleach, and when combined with UV rays from the sun, it can effectively fade stains and kill bacteria on plastic containers.

Vinegar solutions
Vinegar is an effective, eco-friendly, and non-toxic solution for removing 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 use vinegar to remove stains, mix equal parts vinegar and water. The general recommendation is to use one tablespoon of vinegar per cup of water. However, if your container is large, you may need to double or triple the amount of vinegar and water. Soak the stained plastic in this mixture for around 30 minutes to 2-3 hours. Then, rinse the container thoroughly with hot water and wash it with dish soap to remove any residual vinegar scent. You can also leave the solution in the container for up to overnight.
Vinegar is particularly effective at removing stains caused by carotenoids, such as tomato sauce and turmeric. It can also remove water marks. However, it may not be the best option for older, deeply set stains.
If you want to try a different natural cleaning solution, you can use lemon juice or baking soda paste.

Denture tablets
To use denture tablets to remove stains from plastic containers, simply fill the container with warm water and drop in one or two tablets. Allow the tablets to dissolve and the fizzing action to do its work. For very stained containers, you can leave the solution to soak overnight. In the morning, wash the container in hot, soapy water, rinse, and dry.
The fizzing action of the denture tablets, known as effervescence, is powerful enough to dislodge stains from the nooks and crannies of your plastic containers. This method is especially useful for removing tomato sauce or tea and coffee stains from plastic containers.
Additionally, denture tablets can be used to remove the plasticky taste and smell from water bottles and containers. Fill the bottle or container with warm water and a denture tablet, and wait for the fizzing to stop. Pour out the solution, rinse the container, and it's good to go!

Hand sanitiser
If you have a plastic container with stubborn stains, hand sanitiser can be used to remove them. The active ingredient in hand sanitiser, alcohol, can help dissolve certain types of stains on plastic surfaces.
To use hand sanitiser to remove stains, first, apply the hand sanitiser directly onto the stain. Make sure you use enough hand sanitiser to completely cover the stain. Then, let the hand sanitiser sit for about an hour. After this, gently scrub the stain with a moist cloth and wipe the container out with a paper towel. Finally, wash the container with soap and water.

Baking soda
To use baking soda to remove stains from plastic containers, start by sprinkling a thick layer of baking soda on the bottom of the container. You will need to use enough baking soda to completely cover the stain. Next, add a small amount of water to the baking soda to form a thick paste. The paste should be just a little thinner than toothpaste. You want it to spread easily but not be too runny.
Once you have your paste, smear it all over the stained areas of the container. Let the paste sit for 15-30 minutes. After this time, wipe the paste around with a damp cloth, rubbing it well, then rinse with dish soap and warm water. If the stain is still visible, you can give it another 30 minutes and try again.
If the baking soda removes the stain but not the food odors, try crumpling up some newspaper and gently packing it into the container. Seal the container with the lid and let it sit for 1-2 days. Then, discard the newspaper and wash the container with hot, soapy water.
