If you want to bring your yellowed plastic electronics back to life, there are several methods you can try. The discolouration is caused by bromine and exposure to UV light, but you can use common household products like vinegar, bleach, or hydrogen peroxide to whiten the plastic. You can soak the plastic in a mixture of water and vinegar, bleach, or hydrogen peroxide, or scrub it with baking soda or lemon juice. For a more intensive treatment, you can try the Retrobrite process, which involves using UV LED light strips and hydrogen peroxide. With a bit of time and effort, your plastic electronics can be restored to their original colour.

What You'll Learn

Soak in hydrogen peroxide
So, you want to whiten your yellowed plastic electronics, specifically by soaking them in hydrogen peroxide? Well, you've come to the right place. Here's a detailed, step-by-step guide on how to do just that:
First things first, you'll want to gather your materials. You'll need a container, some hydrogen peroxide, and, of course, the yellowed plastic electronics you want to whiten. It's important to use a container that is large enough to completely submerge the plastic pieces you're trying to whiten. Additionally, it is recommended to use 3% or 12% hydrogen peroxide solutions, which can be purchased at most hardware stores or online.
Once you have your materials, it's time to get started. If your electronics are still assembled, carefully disassemble them and remove any non-plastic parts. Then, place the plastic pieces in the container and cover them completely with the hydrogen peroxide solution. Make sure that the container is open or clear, as you will need access to sunlight or a UV lamp later in the process.
Now, this is important: do not let the peroxide dry. Place the container in direct sunlight or under a UV lamp. The UV light is essential to the whitening process, as it reacts with the peroxide and the plastic to remove the yellowing. If you are using sunlight, make sure to turn the pieces over occasionally to ensure even exposure. If you are using a UV lamp, you may want to cover the container with aluminum foil to concentrate the UV light on the pieces.
Let the plastic pieces soak for at least 3-4 hours. For more severe yellowing, you may need to let them soak for 12 to 24 hours or even a few days. Keep an eye on them and adjust the soaking time as needed. Remember, it's important to be patient, as it may take more than one attempt to remove stubborn stains.
Finally, once the plastic has regained its original colour, remove the pieces from the peroxide solution and rinse them thoroughly with clean water. Wash the parts with soap and water to ensure that all residual peroxide is removed. And that's it! Your yellowed plastic electronics should now be nice and white.
A few things to keep in mind: while this method is effective, it may not work on all types of plastic, and the results may be temporary. Additionally, hydrogen peroxide can make plastics more prone to yellowing in the future. Always exercise caution when handling chemicals, and be sure to wear gloves and safety goggles if necessary.

Use vinegar
To whiten yellowed plastic electronics with vinegar, you can try the following methods:
Vinegar Soak
First, remove any plastic pieces from the electronic device. Then, fill a container with equal parts warm water and distilled white vinegar or cleaning vinegar. Submerge the plastic pieces in the mixture and let them soak for at least overnight, but 24 hours is preferable. After soaking, remove the plastic pieces from the mixture, wash them in hot soapy water, and rinse with warm water. The vinegar smell will disappear once the plastic is washed and dried.
Vinegar Scrub
Put on a pair of cleaning gloves to protect your hands from the vinegar. Then, soak a soft cloth or sponge in distilled white vinegar and gently scrub the yellowed areas of the plastic. Let the vinegar sit for a moment, then wipe the area clean with a damp cloth.
Vinegar and Baking Soda
Mix vinegar with baking soda to form a paste. Apply the paste to the yellowed plastic and let it sit for a few hours. Then, use a sponge or towel to rub the paste into the stain before rinsing it off with warm water.
Vinegar and Dawn
Mix two cups of vinegar with a tablespoon of Dawn and some water in the sink. Allow the plastic pieces to soak in the mixture for 15-30 minutes. Use a bristle brush to scrub the pieces, then rinse with water and dry.
It is important to note that vinegar should not be used on all plastics, as it can damage certain types. Always test on a small, hidden area first to ensure it is safe for the specific plastic you are trying to clean.

Bleach
If using bleach, the first step is to mix one tablespoon of liquid chlorine bleach with one cup of warm water. Gloves should be worn to protect the skin. For items that can be submerged, place them in a bucket or bowl filled with the bleach solution and allow them to soak until they return to their original white colour.
For electronic parts that cannot be fully submerged, soak paper towels with the bleach solution and cover the yellowed plastic. Press the paper towels firmly against the surface and keep them moist until the plastic whitens. Re-wet the paper towels as needed.
After removing the plastic from the bleach solution, rinse it with clean water and wash with a mild detergent. Allow the pieces to air dry completely.
It is important to note that bleach should not come into contact with surrounding areas, as it can discolour them. Additionally, always handle bleach with caution and follow safety guidelines.

Peroxide cream
Firstly, it is important to wear gloves and safety goggles for protection. Peroxide cream can be purchased from beauty supply stores. The cream is then applied to the yellowed plastic surface. It is important to ensure a thin layer of the cream covers the entire stained area.
The next step is to cover the plastic piece with plastic wrap. This prevents the cream from drying out too quickly and causing streaking. The plastic is then placed in direct sunlight or under a UV lamp. The sunning process can vary from a few hours to a few days, depending on the severity of the yellowing.
Once the desired colour is achieved, the plastic is washed thoroughly to remove any residual cream. It is important to note that the whitening effect is not permanent, as the yellowing can re-occur over time. Additionally, some people believe that the process may make the plastic more brittle and fragile.

Retrobrite
To use the Retrobrite process, start by lining the outside of a plastic container with UV LED light strips. Then, remove the plastic pieces from the device and place them in the container. Put on gloves and safety goggles, and pour enough 12% hydrogen peroxide into the container to cover the plastic pieces. You can also add a small amount of the "active oxygen" laundry booster TAED as a catalyst. Line the outside of the container with aluminium foil and turn on the lights. Then, leave the parts to soak for 12 to 24 hours. If the plastic pieces float, weigh them down with a stainless steel bolt or screw. If the plastic is still yellow after 24 hours, let it soak for longer.

Frequently asked questions
There are several ways to whiten yellowed plastic electronics. You can use the Retrobrite process, which involves soaking the plastic pieces in hydrogen peroxide and setting them under UV LED light strips. Alternatively, you can soak the plastic in a mixture of bleach and water, or use a peroxide cream and set it under sunlight or UV light.
It is important to identify the type of plastic before attempting to whiten it. ABS plastic, often used in electronics, is known to turn yellow when exposed to UV light. This type of plastic can be whitened using the methods mentioned above.
Household products such as vinegar, baking soda, lemon juice, and rubbing alcohol can be used to whiten yellowed plastic. Simply soak the plastic item in vinegar or rubbing alcohol, or scrub it with baking soda or lemon juice.
