Bleach solutions
To make a bleach solution, mix one tablespoon of chlorine bleach with one cup of hot water. Alternatively, a more potent solution can be made by mixing one part chlorine bleach with ten parts water. This solution can be applied to the stained area of the container using a sponge or damp cloth. Allow the solution to sit for 10 to 15 minutes before rinsing it off. For tougher stains, let the container soak in the solution for up to two hours.
After treating the stain, it is crucial to thoroughly wash the container with hot, soapy water and let it air dry. Bleach should not be left on the plastic for too long, as it can eat away at the material over time. Always ensure that the container is thoroughly rinsed and no residue remains. Avoid exposing bleached containers to direct sunlight, as this may enhance discolouration.
Bleach is particularly effective at removing stains caused by ink, juice, soda, coffee, tea, tomato sauce, and food dyes. It is a powerful tool for breaking down tough stains that refuse to budge with other methods. However, it should be used sparingly and with caution, as overuse or misuse may result in discolouration or weakening of the plastic.

Vinegar soaks
Vinegar is an excellent option for cleaning stained plastic containers. Its acidic properties work wonders in breaking down stain particles. To make a vinegar soak, mix equal parts white vinegar and warm water. You can also use a ratio of one tablespoon of vinegar per cup of water. Next, pour the solution into the stained container and let it soak for 30 minutes to 2 hours. For tougher stains, let the solution sit for up to 12 hours. After soaking, rinse the container thoroughly with hot water.
It is important to note that vinegar may not work on very old food stains. If you are dealing with particularly stubborn stains, try letting the vinegar solution soak for longer or adding a bit of hot water. Additionally, while vinegar is generally safe for use on plastic, it is always a good idea to test a small area first to ensure it does not cause any discolouration.
The vinegar smell will disappear once the container is dry. Not only will vinegar help remove stains, but it can also deodorize and remove grease from your plastic containers.

Baking soda pastes
Baking soda is a gentle abrasive that helps to lift and remove stains and odours from plastic containers. To make a baking soda paste, mix a couple of tablespoons of baking soda with a small amount of warm water. The paste should be slightly thinner than toothpaste, so it spreads easily but is not runny.
Smear the paste all over the stained areas of the container, ensuring that it gets into all the nooks and crannies. You can use a cloth or an old toothbrush to apply the paste. Leave the paste to sit for 15 to 30 minutes. The longer you leave it, the easier it will be to remove the stains.
After the paste has had time to work, wipe it away with a damp cloth, making sure to rub the bottom of the container well. Rinse the container with warm water and dish soap to remove any remaining paste. Wash the container with hot soapy water and air dry.
For stubborn stains, you can also add vinegar to the baking soda paste. This combination is especially effective at removing tomato sauce stains and their lingering aromas.

Denture tablets
To use denture tablets for cleaning plastic containers, fill the container with warm water and add one or two denture tablets, depending on its size. Allow the denture tablets to dissolve and activate, which will cause fizzing. For best results, let the solution sit for at least a couple of hours or preferably overnight. The longer the soak, the more effective it will be at removing stubborn stains and residue.
After soaking, pour out the solution and rinse the container thoroughly with hot, soapy water. Finally, dry the container before using it again. This method is especially useful for removing tomato-based stains, which can seem like permanent stains on plastic containers.
In addition to cleaning plastic containers, denture tablets can also be used to clean a variety of other items, such as mugs, tea kettles, coffee pots, jewellery, and even toilets. They are a great alternative to harsh chemicals and can be used to effectively remove stains, grease, and odours from various surfaces.

Hand sanitiser
If you're looking to remove crud from plastic containers using hand sanitiser, here are some detailed steps you can follow:
Firstly, determine if your container is suitable for this method. If the stain has been left for a long period, the plastic may have faded due to the alcohol in the hand sanitiser drawing out the oils from the plastic. In this case, you may need to use a heat gun to restore the colour or paint over it.
Now, if your container is suitable, pour enough liquid hand sanitiser into the container to completely cover the stain. You can also apply hand sanitiser directly to the stained area if you prefer. Let the hand sanitiser sit for around 45 minutes to an hour.
After this, wipe the container with a paper towel or a soft cloth. You should see the stain transfer onto the paper towel or cloth. Then, wash the container with hot soapy water and air dry it.
If you're looking for an alternative to hand sanitiser, you could try using a paste made from baking soda and water. Apply this paste directly to the discoloured areas, let it sit for 20-30 minutes, and then rinse and dry the container.
