Stained plastic containers are unsightly and off-putting, especially when it's time to eat. Fortunately, there are several methods to restore discoloured plastic containers to their original state. The best method depends on the type of stain and the colour of the plastic. For example, while bleach is highly effective at removing stains from white plastic, it can discolour coloured plastics. Other methods include using vinegar, hand sanitiser, baking soda, denture tablets, lemon, salt, and sunlight.

Using hand sanitiser
Hand sanitiser can be an effective way to remove stains from plastic, as the active ingredient, alcohol, can help dissolve certain types of stains. To use hand sanitiser to remove stains, follow these steps:
- Apply a small amount of hand sanitiser directly onto the stain.
- Let it sit for about an hour.
- Gently scrub the area with a moist cloth.
- Rinse the plastic item thoroughly with water to remove any residue.
- Dry the item.
It is important to note that hand sanitiser should be used wisely when removing stains from plastic. The high alcohol content may cause discolouration if left on the surface for too long. Always test a small area first before applying it to the entire stained surface. Additionally, use protective gloves when handling strong sanitisers to protect your hands from irritation.
Hand sanitiser can be particularly effective for removing ink stains or coffee stains. For more stubborn stains, you may need to repeat the process several times.
If you don't have hand sanitiser, you can also use rubbing alcohol, which has a similar effect due to its high alcohol content. Simply substitute hand sanitiser with rubbing alcohol in the steps above.

Bleach solutions
To remove stains from plastic containers, mix one part chlorine bleach with ten parts water. Apply this mixture to the stained area using a sponge or damp cloth and let it sit for 10 to 15 minutes before washing it off. For liquid stains, a mild bleach solution can be used: mix 1 tablespoon of chlorine bleach with 1 cup of hot water. Soak the stained container for 40 to 45 minutes, then discard the solution and wash the container with hot soapy water.
For coloured plastics, an alternative to bleach is a vinegar solution, which can effectively remove stains without causing discolouration.

Vinegar solutions
Vinegar is a natural cleaner that is generally safe to use on most types of plastic without causing any damage. It is an effective way to remove watermarks and weird odours from plastic. To make a vinegar solution, use one tablespoon of vinegar per cup of water. Pour the solution into the container and let it sit for 1 to 2 hours. For deeper stains, you can also try using 30% cleaning vinegar.
If you are looking to remove yellow stains from plastic, you can soak the plastic in vinegar. However, if the stain is in a container, it is recommended to pour vinegar into the container and let it sit for a few minutes before rinsing it out with soap and water. This will help to dissolve the stain.
Vinegar is a great alternative to bleach, which can be too strong for some users. It is also a more eco-friendly option. However, some people may not like the smell of vinegar, so it is important to wash and rinse the plastic thoroughly after using the vinegar solution. Additionally, some users have reported that vinegar is not effective at removing stains, especially older, deeper stains.

Baking soda paste
If your plastic containers are stained, baking soda paste is a great disinfectant that can clean plastics and remove liquid stains. Here is a step-by-step guide on how to use baking soda paste to restore your plastic items:
Step 1: Create the Baking Soda Paste
In a small bowl, mix 1 to 2 tablespoons of baking soda with warm water to form a paste. The paste should be similar in consistency to toothpaste—thick enough to spread easily but not runny.
Step 2: Apply the Paste
Take your plastic container and smear the paste all over the stained areas. Make sure to cover the stains completely.
Step 3: Let it Sit
Allow the paste to sit on the stained areas for about 20 to 30 minutes. During this time, the baking soda will work to lift the stains from the plastic.
Step 4: Wipe and Rinse
After the waiting period, use a damp cloth to wipe away the paste. Rub the stained areas well to ensure the stain is removed. Finally, rinse the container with warm water and dish soap to remove any residue.
Additional Tips:
- Always rinse your plastic items thoroughly after treating them with any cleaning solution to prevent residue build-up.
- If you don't have baking soda, hand sanitizer can be an effective alternative for removing stains from plastic. Its high alcohol content can help dissolve certain types of stains. Apply a small amount directly to the stain, let it sit for about an hour, and then scrub gently with a moist cloth. Remember to rinse thoroughly afterward to avoid potential discolouration from prolonged contact with the sanitizer.
- For a more organic approach, lemon juice and sunlight can be used to remove stains. Simply rub lemon juice on the stained area and leave the item exposed to sunlight for a day or two.
By following these simple steps and tips, you can effectively remove stains from your plastic items and restore them to their former glory!

Sunlight
Understanding Plastic and Sun Damage
Plastic is a synthetic material that contains a lot of oils, which give plastic its colour and shine. However, the sun's ultraviolet (UV) rays can slowly dry out these oils, causing the plastic to lose its colour and become brittle over time. This process occurs at the molecular level, making it challenging to restore severely damaged plastic.
Using Sunlight to Restore Plastic
Now, let's explore how we can harness the power of sunlight to restore stained plastic:
- Lemon Juice and Sunlight: Cut a fresh lemon in half and rub the lemon juice onto the stained plastic, ensuring it covers the stains. Place the plastic item in direct sunlight for a few hours to a couple of days. The combination of lemon juice and sunlight helps remove yellow stains, especially on plastic cookware and storage containers.
- Hydrogen Peroxide and Sunlight: If your plastic item has turned yellow, you can use hydrogen peroxide to restore it. Cover any coloured areas with tape to protect them, then apply a layer of 12% hydrogen peroxide cream to the stained area. Place the item in a clear plastic bag and set it in direct sunlight for about four hours. Rotate the bag every hour to ensure even exposure to sunlight. Finally, rinse off the cream with a damp rag.
- Gentle Heat and Sunlight: For plastic items that have lost their shine due to sun damage, you can use gentle and even heat to draw out the remaining oils from the interior of the plastic. Place the item in direct sunlight for a few hours, being careful not to let it get too hot and melt. This process can help restore some shine to the plastic.
- Peroxide Cream: If you're dealing with stained plastic appliances or electronics, you can apply a thin layer of peroxide cream to the affected areas. Cover the item with plastic wrap and expose it to sunlight or UV light for 12 to 24 hours. This method is effective but may require safety goggles and gloves.
Remember, when using sunlight to restore plastic, it's important to monitor the process closely. Too much exposure to sunlight can further damage the plastic, so regular rotation and checking are necessary. Additionally, always rinse and dry the plastic item thoroughly after treating it with any substance.
