What You'll Learn
Using bleach
Bleach is a highly effective method for removing stains from plastic containers. It can be used to remove ink, juice, soda, coffee, tea, tomato sauce, and paste stains, as well as food dyes. However, it is important to note that bleach can discolour coloured plastics, so it is advisable to test a small area first. When using bleach, always wear rubber gloves to protect your skin.
To use bleach to remove stains from a plastic container, start by mixing one tablespoon of chlorine bleach with one cup of hot water. You can also use powdered oxygen bleach or hydrogen peroxide bleach. If you are using powdered oxygen bleach, create a paste by mixing it with warm water. Apply the paste to the stained area and cover it with plastic wrap to keep it moist. Let it sit for at least four hours, or overnight for best results.
If you are using liquid bleach, pour the solution into the stained container, ensuring that all the stained areas are covered. Let the container soak for at least one hour, or up to overnight, until the stain has lifted. For stubborn yellow stains, you may need to soak the container in bleach for 1-2 hours.
After soaking, pour out the bleach solution and wash the container thoroughly with hot, soapy water. You can also put the container in the dishwasher for a more thorough cleaning. Be sure to rinse the container well to ensure no residue remains, as trace amounts of bleach can be harmful.
Finally, let the container air dry. To remove any remaining bleach smell, place the container outside in direct sunlight for two full days. The sun's ultraviolet rays will also help to fade any remaining stains.

Hand sanitiser
To use hand sanitiser to remove stains, first, apply some sanitiser directly onto the stain. You may need to use enough sanitiser to completely cover the stain. Then, let it sit for around an hour. Finally, wipe the container out with a paper towel and give it a good wash. You should notice the stain transferring onto the paper towel as you wipe.
There are several other methods for removing stains from plastic containers. One is to use vinegar, which is a food-safe, natural cleaner. To use vinegar, mix equal parts of white vinegar and warm water and soak the stained plastic in this mixture for at least an hour or even overnight. Then, rinse the container and wash it with dish soap to remove any trace of the vinegar scent.
Another option is to use baking soda, which can be made into a paste by mixing a tablespoon or two with a little water. Apply this paste to the stained area of the container and let it sit for 20-30 minutes before wiping it around with a damp cloth and rinsing with soap and water.
Yet another alternative is to use denture tablets, which can be placed in water inside the container and left to dissolve and work their magic. After an hour or two, wash the container with warm soapy water and dry it with a clean dish towel.
Remember to always test a small area first when using any new cleaning product or method, and to wear protective gloves when handling strong sanitizers or other potential irritants.

Baking soda
Stains on plastic containers can be unsightly and off-putting, especially when it's time to reuse them. Baking soda is a natural ingredient that can be used to remove these stains without the use of harmful chemicals. It is a gently abrasive substance that helps loosen stains and odours. Here is a step-by-step guide on how to use baking soda to remove stains from plastic containers:
Step 1: Create a Baking Soda Paste
In a small bowl, mix baking soda with water to form a thick paste. The amount of baking soda and water may vary depending on the size of the stained area and the severity of the stain. A good starting point is to mix 1-2 tablespoons of baking soda with enough warm water to create a spreadable paste.
Step 2: Apply the Paste
Using a clean cloth, sponge, or your fingers, apply the baking soda paste directly to the stained areas of the plastic container. Make sure to cover the entire stained area generously.
Step 3: Let it Sit
Allow the paste to sit on the stained areas for 15 to 30 minutes. During this time, the baking soda will work to loosen and lift the stain from the plastic.
Step 4: Rinse and Inspect
After the waiting period, use a moist cloth or sponge to gently wipe away the paste. Rinse the container with warm water to ensure all residue is removed. Inspect the container to see if the stain has been removed.
Step 5: Repeat if Necessary
If the stain persists, repeat the process as needed until the stain is gone.
Additional Tips:
- Be careful not to scrub too hard when applying or rinsing off the paste, as baking soda is abrasive and can potentially scratch the plastic.
- If the baking soda removes the stain but not the odour, crumple some newspaper and gently pack it into the container. Seal the lid and let it sit for 1-2 days. Then, discard the newspaper and wash the container with hot, soapy water.
- For tough stains, especially those caused by food dyes, tomato sauce, or other highly pigmented foods, consider using a combination of methods. For example, you can first treat the stain with lemon juice and sun exposure, then follow up with the baking soda paste for a thorough clean.
By following these steps and tips, you can effectively use baking soda to remove stains from your plastic containers, making them look and smell fresh again!

Lemon juice
To remove stains from plastic containers with lemon juice, start by rubbing a cut lemon over the stained areas. If you don't have a fresh lemon, you can also use bottled lemon juice, ensuring you pour enough to cover the stain. Allow the lemon juice to soak into the stain for around 15 minutes. For deeper stains, you may wish to leave the lemon juice for 2-3 hours.
For more stubborn stains, you can also add salt to the lemon juice to create a scouring paste. The salt grains will act as a natural scrub to help dislodge stain particles.
After allowing the lemon juice to soak, rinse the container with water and, if necessary, a mild soap. You can then leave the container to air dry.
For deeper stains, you can also try leaving the lemon-soaked container outside for 1-2 days. The sun's UV rays will work with the lemon juice to help fade stains and kill bacteria.

White vinegar
To use white vinegar to clean stained plastic containers, you can try the following methods:
Soaking Method
Fill the stained plastic container with a solution of equal parts white vinegar and water. Allow the container to soak for several hours, or even overnight. Then, empty the container and wash it with dish soap and water. This method is especially useful for removing stains caused by tomato sauce, turmeric, or buffalo sauce.
Spray Bottle Method
Create a solution of equal parts white vinegar and water in a clean spray bottle. Spray the solution liberally onto the stained plastic container, ensuring that the affected areas are thoroughly soaked. Use a clean cloth or sponge to wipe the solution around the container and scrub any areas with built-up grime. Finally, rinse the container with clean water and dry it with a towel.
Vinegar and Baking Soda Method
Combine 1 2/3 cups of baking soda, 1/2 cup of liquid soap, and 2 tablespoons of white vinegar with 1/2 cup of water to form a paste. Apply this paste to the stained areas of the plastic container and let it sit for a while. Then, scrub the paste into the plastic using a cloth or an old toothbrush and rinse it off with water.
It is important to note that vinegar may not be effective for removing all types of stains, and it may require multiple applications or the use of a stronger acid like bleach. Additionally, while vinegar is generally safe for cleaning plastic, it should be avoided on certain materials like natural stone, stainless steel, and rubber, as it can cause corrosion or discolouration.
