Soak in vinegar and water
So, you want to remove those yellow stains from your plastic containers, utensils, and toys? White vinegar is a safe alternative to harsh cleaners and works wonders on yellowed plastic. Here's a detailed, step-by-step guide on how to do it:
Step 1: Prepare the Vinegar Solution
Mix one part white vinegar with one part water in a container. You can also add a tablespoon of dish soap to the mixture for extra cleaning power. If you're dealing with tough stains, you can use a higher ratio of vinegar to water, such as two cups of vinegar to one cup of water.
Step 2: Soak the Plastic Items
Submerge the yellow-stained plastic items in the vinegar solution. Make sure that the items are completely covered by the liquid. If you're removing stains from a plastic container, simply pour the vinegar mixture inside it. Let the plastic items soak for at least two to three hours. For tougher stains, you can leave them to soak overnight or even up to 24 hours. The longer they soak, the more effective it will be at removing stubborn stains.
Step 3: Rinse and Wash
After soaking, remove the plastic items from the vinegar solution and rinse them thoroughly with clean water. You can then wash the items with soap and warm water to remove any remaining vinegar residue and ensure they are completely clean.
Step 4: Dry and Enjoy
Once rinsed and washed, dry the plastic items with a clean towel or let them air dry. The vinegar smell will disappear once the plastic is thoroughly washed and dried. And that's it! Your plastic containers, utensils, or toys should now be stain-free and looking much brighter.
This method is a safe and effective way to remove yellow stains from plastic without resorting to harsh chemicals. It may take a little time, but the results will be worth it!

Use a lemon juice and salt scrub
To remove yellow stains from a plastic container using lemon juice and salt, start by cutting a lemon in half and rubbing the lemon over the plastic so that the juice covers the stains. Then, sprinkle salt over the lemon juice-covered stain. Take the item outside and let it sit in the sun for a few hours to a whole day. The ultraviolet rays of intense sunlight, combined with the citric acid in the lemon and the abrasive quality of the salt, will help remove the yellow stains. After this, rinse the container with water and dry it.
This method is especially effective on plastic storage containers, utensils, and cutting boards. Make sure you spread the lemon juice and salt into the nooks and crannies of a stained piece of plastic, such as the yellowing marks on a cutting board.
If you are cleaning a smaller item, such as a child's toy, you can also try soaking the item in lemon juice for at least an hour in the sun. After soaking, use a brush to scrub off the toy, then rinse and dry it.

Bleach solution
Bleach is a popular method for removing yellow stains from plastic containers. It is a powerful tool for breaking down tough stains that refuse to budge otherwise. However, it should be used with caution as it can damage the plastic if not used properly.
To use the bleach solution method, start by mixing one part chlorine bleach with ten parts water. Always test the bleach on a small section of the plastic first to ensure it doesn't harm the surface. Wear protective gear, such as a respirator mask, gloves, and goggles, and work in a well-ventilated area when using bleach.
Once you've mixed the solution, apply it to the stained area of the plastic container using a sponge or damp cloth. Let the solution sit for 10 to 15 minutes before rinsing it off with warm water. If the stain is particularly stubborn, you can let the solution sit for up to an hour or even overnight.
After rinsing, wash the container with mild soap and water to remove any residue. You can also place the container in the dishwasher for a thorough cleaning. Avoid exposing the container to direct sunlight immediately after cleaning, as this may enhance discolouration.
For electronic parts, a different approach is needed. In this case, fill a sink with an 8:1 water-to-bleach mix. Put on gloves for protection and submerge the plastic in the solution. Soak the item until it returns to its original white colour. Finally, remove it from the solution, wash it with mild soap, and rinse it thoroughly.

Baking soda paste
Baking soda and water form a natural, gentle abrasive paste that can effectively remove light yellow stains from plastic containers. To make the paste, mix two tablespoons of baking soda with one teaspoon of water. If the paste is too thick, add a few more drops of water to adjust the consistency.
Once you have the desired consistency, use a soft sponge to spread the paste on the stained areas of the container. Let the paste sit for about five to ten minutes. After, dampen the sponge and gently scrub the container. Wash the container in hot, soapy water and rinse it well. Repeat the process if necessary.
For tougher stains, you can also try using a mixture of one part chlorine bleach and ten parts water. Apply this mixture to the stained areas with a sponge or damp cloth and let it sit for 10 to 15 minutes before rinsing. Be sure to handle bleach with care and avoid exposing bleached items to direct sunlight immediately after cleaning, as this may enhance discolouration.
Additionally, you can try using vinegar to remove yellow stains. Fill the container with equal parts warm water and distilled white vinegar or cleaning vinegar, and let it sit overnight or for up to 24 hours. Then, pour out the mixture, wash the container with hot soapy water, and rinse it with warm water.
