What You'll Learn
Soak containers in vinegar
Soaking containers in vinegar is an effective way to remove yellow stains from plastic. This method is particularly useful for food containers stained by tomato sauce, buffalo sauce, turmeric, or other foods. White vinegar is a gentle, yet powerful cleaning agent that is safe for use on items that come into contact with food and children.
To start the process of removing stains by soaking containers in vinegar, you will need to prepare a mixture of vinegar and water. Combine equal parts of white vinegar and water in the stained container. It is recommended to use distilled white vinegar or cleaning vinegar, which has a higher concentration. If you are cleaning multiple containers or items, you can prepare a large batch of the vinegar solution in a sink or basin. Ensure that the vinegar solution completely covers the stained portions of the container.
After mixing the vinegar and water, let the containers soak for an extended period. The soaking time can vary depending on the severity of the stains. For lighter stains, 2 to 3 hours of soaking may be sufficient. However, for more stubborn stains, you can leave the containers to soak overnight or even for 24 hours. During this time, the vinegar solution will work to break down and lift the yellow stains from the plastic.
Once the soaking period is complete, you can pour out the vinegar solution and proceed to rinse the containers. Wash the containers with hot, soapy water and then rinse them thoroughly with warm water. This step ensures that any remaining vinegar residue is removed, along with the loosened stains. If desired, you can repeat the process, especially if there are any stain remnants remaining.
Soaking containers in vinegar is a simple, yet effective method for removing yellow stains from plastic. It is a gentle alternative to harsh chemical cleaners and can be easily performed with household items. By following the steps outlined above, you can restore your plastic containers to their original, stain-free appearance.

Use denture tablets
If your plastic containers have yellow stains, you can use denture tablets to get rid of them. This method is especially useful if the stains are caused by oily or greasy food residue.
To use denture tablets, start by filling the container with warm water. Then, add a single denture tablet and let it soak for at least a couple of hours. For more stubborn stains, it is recommended to leave the container to soak overnight. The denture tablet will dissolve in the water, activating a cleaning agent that will help lift off the stains and bacteria.
After letting the solution work its magic, pour out the mixture and wash the container thoroughly in hot, soapy water. Finally, rinse and dry the container, and you should be left with spotless, stain-free plastic.
Denture tablets are a great, budget-friendly cleaning hack that can be used for more than just dentures and plastic containers. They are made from non-toxic ingredients, including baking soda, and can be used to clean everything from burnt pots and pans to coffee-stained mugs.

Bleach solution
Bleach is a powerful tool for removing stubborn yellow stains from plastic containers. To make a bleach solution, mix one part chlorine bleach with ten parts water. Alternatively, you can use one tablespoon of bleach per cup of water. Before applying the bleach solution, ensure that the plastic is at room temperature and free of any visible food particles. Test the bleach on a small section of the plastic first to ensure it won't harm the material. When handling bleach, wear protective gear such as a respirator mask, gloves, and goggles, and work in a well-ventilated area.
Once you've prepared the bleach solution, apply it to the stained areas of the plastic container using a sponge, damp cloth, or old toothbrush. Scrub the bleach into the plastic, pressing hard to ensure the solution reaches into the pores of the plastic. Let the bleach solution sit on the plastic for 10 to 15 minutes. For stubborn stains, you can let the solution sit overnight or for up to 24 hours.
After the bleach solution has had time to work, rinse the plastic container thoroughly with soap and water to remove any residue. Wash the container in hot, soapy water or place it in the dishwasher for a thorough cleaning. Avoid exposing the container to direct sunlight immediately after cleaning, as this may enhance discoloration.
For plastic items that cannot hold liquid, adjust the application method. Pour the bleach solution into a separate container and place the plastic item inside, ensuring it is fully submerged. Rinse the item with clean water afterward to remove any residual bleach.

Rubbing alcohol
To start, ensure that the plastic container is at room temperature and free of any visible food particles. If the container is not at room temperature, you can place it in a sink and run lukewarm water over it until it reaches the desired temperature. Next, pour rubbing alcohol (isopropyl alcohol) into the container, filling it until all the yellowed areas are covered. If the container has a wide opening, you may need to tilt it slightly to ensure that the alcohol comes into contact with the stained areas. Allow the alcohol to sit in the container for about 10 to 15 minutes. The duration may vary depending on the severity of the stains.
Once the time has passed, pour out the alcohol. Rinse the container with clean water to ensure no alcohol remains. Then, wash the container thoroughly with hot, soapy water. If necessary, use a soft sponge or cloth to gently scrub away any remaining stains. Finally, rinse the container well with warm water to remove any soap residue.
If you don't have enough rubbing alcohol to fill the container, there is an alternative method. Simply soak some paper towels in the alcohol and line the inside of the container with them, ensuring they cover the stained areas. Leave the paper towels in place for a similar duration, then remove and continue with the rinsing and washing steps as outlined above.
It is important to note that while rubbing alcohol is generally safe for use on plastic, it is always a good idea to test a small area first if you are concerned about potential discolouration or damage. Additionally, ensure the area is well-ventilated when using rubbing alcohol, and avoid contact with skin and eyes. Keep it out of the reach of children.

Baking soda paste
To remove yellow stains from plastic containers using baking soda paste, start by creating the paste. Mix water and baking soda in a cup or similar container until the solution forms a paste. You can also add dish soap to the paste. Next, apply the paste to the yellowed plastic. If the container cannot hold liquid, pour the paste into a separate container and place the plastic item inside.
Let the paste sit for several hours. Then, scrub the paste off with a sponge or rag, dampening the sponge if necessary. Finally, rinse the container well with warm water and dry with a towel.
If you are removing stains from a plastic container, you can also pour the paste directly inside. Alternatively, you can apply the paste to a sponge and scrub the stained areas. Let the paste sit for five to ten minutes, then dampen the sponge and gently scrub the plastic. Wash the container in hot, soapy water and rinse well. Repeat if needed.
For tough stains, you can try a different cleaning method first, such as soaking the container in vinegar or denture tablets, before applying the baking soda paste.
