Soak in vinegar and water
Vinegar is a natural plastic stain remover that is both effective and eco-friendly. To use vinegar to remove stains from a plastic bowl, follow the steps outlined below:
Step 1: Prepare the Vinegar Solution
Mix equal parts white vinegar and warm water. For a more concentrated solution, you can use undiluted white vinegar. Alternatively, for a larger container, use one tablespoon of vinegar per one cup of water.
Step 2: Soak the Bowl
Completely submerge the stained bowl in the vinegar solution. Ensure that the solution covers all stained areas of the bowl. Let the bowl soak for 15 to 30 minutes. For more stubborn stains, you may let the bowl soak for up to an hour or two.
Step 3: Scrub Gently
After soaking, use a soft sponge or cloth to gently scrub the stained areas of the bowl. This helps to loosen and remove any remaining stains. Be careful not to use a harsh scrubber that could scratch the plastic.
Step 4: Rinse and Dry
Once you have finished scrubbing, thoroughly rinse the bowl with warm water to remove any residual vinegar and stains. Dry the bowl immediately with a clean cloth to prevent water spots and promote a streak-free finish.
By following these steps, you can effectively use vinegar and water to remove stains from your plastic bowls, restoring them to their original white colour.

Bleach solution
Bleach is a highly effective method to remove stains from plastic bowls. However, it should be used with caution, especially when dealing with food-safe plastics. Here is a step-by-step guide on how to use a bleach solution to turn stained plastic bowls white again:
Preparation:
Before using bleach, it is important to take some safety precautions. Ensure you are working in a well-ventilated area to avoid inhaling the fumes, which can be harmful. Always wear gloves to protect your skin from irritation. Avoid mixing bleach with other cleaning products, especially inside the plastic containers, as certain combinations can produce toxic gases.
Mixing the Bleach Solution:
To create an effective bleach solution, mix one part chlorine bleach with ten parts water. For smaller containers, a common recommendation is to mix one tablespoon of bleach with one cup of water. You may need to adjust the amounts accordingly to fully cover the stain.
Applying the Bleach Solution:
Apply the bleach solution to the stained areas of your plastic bowl using a sponge or a damp cloth. Make sure to cover the entire stained area. Let the solution sit for at least 10-15 minutes, or longer if needed. The bleach will work to lift the stains from the plastic.
Rinsing and Washing:
After the bleach solution has been applied and the stain has lifted, it is important to thoroughly rinse the bowl with water to ensure no bleach residue remains. Wash the bowl with soapy water or run it through the dishwasher to completely remove any traces of bleach.
Post-Treatment Care:
Avoid exposing the treated plastic bowl to direct sunlight immediately after cleaning, as this may enhance discoloration. Always ensure your plastic bowls are well-rinsed and dried before their next use.
While bleach is a powerful stain remover, it may not work for all types of stains. Additionally, it may be challenging to completely eliminate the smell of bleach from plastic containers. Always exercise caution when using bleach, and consider testing the solution on a small area first if you are unsure of the results.

Baking soda paste
Baking soda is a gentle abrasive that can be used to remove tough stains from plastic bowls. To make a baking soda paste, mix baking soda with water until it reaches a thick paste consistency. The paste should be just a bit thinner than toothpaste, allowing it to spread easily without being runny.
Apply the paste to the stained areas of the bowl and let it sit for 15 to 30 minutes. After this, use a damp cloth or sponge to wipe the paste around the bowl, rubbing it well to scrub the stain. Finally, rinse the bowl with dish soap and warm water to remove any residue. Repeat the process if necessary.
For more stubborn stains, you can also add hydrogen peroxide to the baking soda and water paste. Apply this paste to the stain and let it sit for a few hours before rinsing thoroughly. Sunlight can also help fade discolouration, so placing the bowl in direct sunlight for several hours after rinsing can be beneficial.
It is important to note that while baking soda is generally gentle, it should be used with caution on plastic, as some plastics may be more sensitive to abrasion. Additionally, always rinse plastic bowls thoroughly after using the baking soda paste to ensure no residue is left behind.

Lemon juice and sun
Lemon juice is an effective natural stain remover for plastic containers. It acts as a bleaching or whitening agent, removing stains and disinfecting the container. The acid in the lemon juice, combined with the sun's UV light, will remove discolouration and kill bacteria.
To use lemon juice and the sun to turn your plastic stained bowls white, first rub lemon juice onto the stained areas of the bowl. You can cut a lemon in half and rub it directly onto the stain, or you can pour lemon juice onto the stain. Leave the lemon juice on the stain for around 15 minutes to allow it to soak in.
Next, place the bowl in direct sunlight. Leave the bowl in the sun for one to two days. The sun's UV light will naturally bleach the bowl, removing discolouration.
Finally, rinse and wash the bowl as usual. You may need to wash the bowl as you regularly would after this process because the area where the lemon juice was applied might be a bit stiff.
