Yellowing of plastic is a common issue, often caused by exposure to sunlight, fluorescent lighting, or heat. While it may seem like an eyesore, there are several effective methods to restore discoloured plastic to its original state. This includes using household products such as vinegar, baking soda, and lemon juice, as well as commercial products like bleach and hydrogen peroxide. The specific approach may vary depending on the type of plastic and the extent of yellowing, but with the right techniques, you can effectively address the issue and restore the aesthetic appeal of your plastic items, including faucets.

Soak in a hydrogen peroxide solution
Soaking plastic items in hydrogen peroxide is an effective way to remove yellow stains and restore discoloured plastic to its original colour. This method is ideal for small plastic items that have turned entirely yellow, rather than items that are only stained in one spot.
To start, you will need to fill a plastic bag or container with enough hydrogen peroxide to cover the plastic item. Then, place the item in the container and set it out in direct sunlight. If the plastic item floats, weigh it down with something heavy, like a stainless steel bolt or screw. Leave the item to soak for 3 to 4 hours, or longer if it is still yellow after the initial soak. Finally, rinse the item with clean water.
If you are removing stains from a plastic container, simply pour the hydrogen peroxide directly into the container and let it sit for a few minutes before rinsing.
While hydrogen peroxide is a safer alternative to bleach, it is still a chemical that requires caution when handling. It is always recommended to wear gloves and work in a well-ventilated area when using this product. Additionally, if you are unsure about using hydrogen peroxide on a specific type of plastic, it is best to test it on a small, inconspicuous area first.
For a more intensive cleaning method, you can try the Retrobrite process. This involves lining the outside of a plastic container with UV LED light strips and pouring enough 12% hydrogen peroxide into the container to cover the plastic pieces. Then, line the outside of the container with aluminium foil, turn on the lights, and leave the parts to soak for 12 to 24 hours. This method is specifically used to remove yellowing from electronics, such as computers and game consoles.

Bleach as an alternative
Bleach is an effective alternative to other cleaning solutions for unyellowing a plastic faucet. It is a heavy chemical that can make plastic brittle over time, so it should be used sparingly. When using bleach, it is important to wear protective gear, such as a respirator mask, gloves, and goggles, and to work in a well-ventilated area.
To use bleach to unyellow a plastic faucet, create a bleach solution by mixing one tablespoon of liquid chlorine bleach with one cup of warm water. You can also use powdered oxygen bleach instead of liquid bleach. The amount of bleach used should be about one tablespoon per cup of water.
Once the bleach solution is ready, submerge the plastic faucet in it and let it soak until the yellow colour fades. This may take anywhere from 10 minutes to a few hours, or even overnight, depending on the severity of the staining. If the plastic is only stained in a small area, you can use a sponge to apply the bleach solution directly to the stain. Cover the paste with plastic wrap to keep it moist and activated.
After soaking or applying the bleach solution, scrub the plastic with a brush or sponge to remove any remaining stains. Finally, rinse the plastic faucet thoroughly with soap and water to remove any residual bleach.
It is important to note that bleach may not be suitable for all types of plastic, especially electronic parts. Always test the bleach on a small, inconspicuous area of the plastic first to ensure it doesn't cause any damage.

Baking soda and water paste
Baking soda and water can be combined to form a natural, gentle abrasive paste that effectively removes light staining from plastic. This paste can be used to clean yellowed plastic faucets, restoring them to their original appearance.
To make the paste, mix two tablespoons of baking soda with one teaspoon of water. If the paste is too thick to spread, add a few more drops of water. The paste should be thick but spreadable.
Once you have achieved the desired consistency, spread the paste onto the stained areas of the faucet using a soft sponge. Let the paste sit for about 5-10 minutes. After this, dampen the sponge and gently scrub the faucet, working the paste into the plastic.
Rinse the faucet with warm, soapy water to remove the paste and any remaining residue. If necessary, repeat the process until the yellow stains are removed.
This method is a safe and effective way to clean yellowed plastic, but it may require some elbow grease for best results. It is important to note that, while baking soda is a gentle abrasive, it should still be used with care to avoid any potential scratching or damage to the plastic surface.

Vinegar and water solution
Vinegar is a popular cleaning solution for faucets due to its ability to break down grime deposits and mineral buildup. However, it is important to note that vinegar is an acid and may damage different finishes. Thus, it is recommended to test a small area of the faucet first to ensure the vinegar does not ruin the finish.
To clean a plastic faucet with a vinegar and water solution, start by mixing equal parts water and vinegar. You can fill a plastic bag with this mixture, submerge the faucet head in it, and secure the bag with a rubber band. Let the faucet head soak for 30 minutes to one hour, then remove the bag. For more sensitive fixture finishes, do not exceed 30 minutes. Alternatively, you can spray the vinegar and water mixture directly onto the faucet head or soak a cloth with the mixture, secure it around the faucet head, and let it sit for 30 minutes.
After soaking, scrub the faucet head with a toothbrush or scrub brush to remove any remaining residue and grime. You can also use a mild pH-neutral cleaner or a mixture of citric acid and water for tougher stains. Rinse the faucet head thoroughly with water to remove any remaining solution.
For extra-tough stains, you can add baking soda to the vinegar and water mixture. The baking soda will react with the vinegar to create a fizzy cleaning solution that can help loosen and remove stubborn buildup. You can also create a baking soda paste by combining baking soda with water and applying it directly to the faucet head. Let it sit for 30 minutes, then scrub and rinse.

Lemon juice for small plastic toys
Lemon juice can be used to remove yellowing from small plastic toys. Soak the toys in lemon juice for at least an hour, allowing the acidic properties of the juice to break down the yellowing. This method is natural and citrusy, and it is effective for small plastic toys.
There are other methods to unyellow plastic, such as using a bleach solution. However, bleach should be handled with caution as it is a strong chemical. When using bleach, always wear gloves and work in a well-ventilated area. Avoid using bleach on coloured plastics, as it may cause discoloration. Instead, use bleach on white or clear plastics that have yellowed over time. To use bleach, submerge the plastic in a mixture of 8 parts water and 1 part bleach, and allow it to soak until it turns white again.
Another alternative is to use hydrogen peroxide, which is a mild bleach. Apply a small amount of hydrogen peroxide to a clean cloth or sponge, and gently rub it onto the yellowed plastic in circular motions until the yellowing fades away. Hydrogen peroxide is safer than bleach, but it still requires caution when handling. Always wear gloves and work in a well-ventilated area when using this method.
Additionally, a homemade paste made with baking soda and dish soap can be effective in removing yellowing from plastic toys. Mix equal parts baking soda and dish soap to create a thick paste, and apply it to the yellowed plastic surface. Use a soft cloth or sponge to rub the paste in circular motions, then rinse off the paste with warm water and pat dry. The abrasive nature of baking soda combined with the cleaning power of dish soap will help remove stains and yellowing.
It is important to note that exposure to sunlight, fluorescent lighting, and heat can contribute to plastic yellowing. To prevent discoloration, store plastic items in a cool, dark place. Some types of plastic, such as polyvinyl chloride (PVC), are more prone to yellowing due to their chemical composition.
