Bleach solutions
Bleach is a powerful cleaning agent that can be used to remove stubborn stains from plastic containers. It is important to note that bleach should be handled with care and diluted with water before application. To create a potent bleach solution, mix one part chlorine bleach with ten parts water.
Preparation:
- Ensure the plastic container has been washed and is free of any stuck-on food or debris.
- Prepare the bleach solution by mixing one tablespoon of chlorine bleach with one cup of water. Always follow the instructions on the bleach packaging for dilution ratios and safety precautions.
- If you are concerned about using bleach on food containers, consider performing a patch test on a small, hidden area of the plastic to ensure it does not cause discolouration.
Application:
- Apply the bleach solution to the stained area of the plastic container using a sponge or damp cloth.
- Allow the solution to sit on the stain for at least one hour, or up to overnight, depending on the severity of the stain.
- After the stain has lifted, thoroughly rinse the container with water to remove any traces of bleach.
Additional Tips:
- For extra stubborn stains, you can increase the concentration of bleach by using one part bleach to five parts water.
- If you are concerned about using bleach, you can try alternative methods such as denture tablets, vinegar solutions, or soaking the container in hot water.
- Avoid exposing bleached items, especially plastic containers, to direct sunlight immediately after cleaning, as this may enhance discolouration.
By following these steps and taking the necessary precautions, you can effectively use a bleach solution to remove white stains from your plastic containers.

Vinegar solutions
Vinegar is a natural cleaner that is generally safe to use on most types of plastic without causing any damage. It is also eco-friendly, non-toxic, and food-safe, making it perfect for cleaning food containers.
To clean your plastic containers with vinegar, mix equal parts water and vinegar, using one tablespoon of vinegar per cup of water. Pour the solution into the stained container and let it soak for 2 to 3 hours. Afterward, drain the vinegar solution, then wash and dry the container. The vinegar smell will disappear after it dries.
For tougher stains, you can try using a higher concentration of vinegar. One source recommends using 30% cleaning vinegar, while another suggests using 5% distilled white vinegar. If you don't have distilled white vinegar, you can use regular white vinegar instead.
In addition to removing stains, vinegar can also be used to eliminate odors and hard water spots from your plastic containers.

Baking soda paste
Baking soda is a great cleaning agent that can be used to remove stains from plastic containers. Here is a step-by-step guide on how to use baking soda paste to effectively remove stains:
Step 1: Prepare the Baking Soda Paste
Start by sprinkling a thick layer of baking soda on the bottom of the container. Gradually add water to the baking soda and mix until a thick paste forms. The paste should be slightly thinner than toothpaste, allowing it to spread easily without being runny. The amount of baking soda and water required may vary, so adjust as needed to achieve the desired consistency.
Step 2: Apply the Paste to the Stained Areas
Once the paste is ready, use a spoon or your fingers to smear the paste all over the stained areas of the container. Make sure to cover the stains completely and evenly. This method is particularly useful for removing stains from the sides of containers.
Step 3: Let the Paste Sit and Work Its Magic
After applying the paste, let it sit on the stained areas for at least 30 minutes. During this time, the baking soda will work to lift and remove the stains from the plastic. If the stains are particularly stubborn, you can leave the paste on for an additional 30 minutes or longer, checking periodically to see if the stains have disappeared.
Step 4: Wipe and Rinse the Container
Once the stains are no longer visible, use a damp cloth to wipe away the baking soda paste from the container. Rinse the container thoroughly with warm water and, if desired, use a mild dish soap to ensure all traces of the paste are removed. Finally, allow the container to air dry or towel dry before using it again.
By following these steps and allowing the baking soda paste to penetrate and break down the stains, you can effectively remove them from your plastic containers, leaving them looking clean and refreshed. This method is a simple, yet powerful way to restore the appearance of your plasticware.

Hand sanitiser
If you have hand sanitiser stains on your plastic containers, there are a few methods you can try to remove them. Firstly, it is important to note that if the stain has been left for a long time, the plastic may have faded due to the high amounts of alcohol in hand sanitiser drawing out the oils from the plastic. In this case, you may not be able to remove the stain with cleaning solutions, and instead, you could try using a heat gun to restore the colour or painting over the area.
For fresh hand sanitiser stains, you can try the following methods:
If you have a lot of hand sanitiser, you can try using it to remove hand sanitiser stains from your plastic containers.

Then, wipe the container with a paper towel and wash the container with soap and water.
Vinegar
White vinegar is an effective cleaning solution for removing hand sanitiser stains from plastic. Its acidic properties break down stain particles. To use this method, mix equal parts vinegar and water in a spray bottle and spray the solution onto the stained areas. Let it sit for a few minutes, then use a scrub brush to remove the stains. Finally, rinse the container with clean water.
Dish Soap
Create a cleaning solution by mixing one part mild dish soap with ten parts water. Dip a microfiber cloth into the solution, then use it to wipe down the stained areas. Finally, dry the container with a dry cloth.
Bleach
Bleach is a powerful cleaning agent that can be used to remove hand sanitiser stains from plastic. However, it should be used with caution as it can be harmful and discolour coloured plastics. To use this method, mix one tablespoon of bleach with one cup of water. Place your plastic container in a larger container and pour in the bleach solution. Let the container soak for at least one to two hours, then wash and dry it.
It is important to note that these methods are for removing hand sanitiser stains from plastic containers. If you are trying to remove other types of stains, the methods may vary.
