Soak in hydrogen peroxide
So, you want to restore some old plastic items from the 1950s to their former glory? Well, you've come to the right place. Here's a detailed, step-by-step guide on how to do just that using hydrogen peroxide.
First things first, you'll want to use 3% hydrogen peroxide for this process. If your plastic item has any non-plastic parts, be sure to remove them. Now, fill a plastic container or bag with enough hydrogen peroxide to cover the plastic item. If your item has a lot of surface area, you may want to use a container that is large enough to accommodate the item and then pour in the hydrogen peroxide.
Once you have your item submerged, place it in direct sunlight. The UV rays from the sun, in combination with the hydrogen peroxide, will work to turn your plastic from yellow back to white. Leave your item to soak for 3 to 4 hours. If your item is particularly yellowed, you may need to leave it for longer. You could also try the Retrobrite process, which involves lining the outside of the container with UV LED light strips and covering it with aluminium foil. This ensures a more concentrated application of UV light.
After your item has soaked, give it a rinse with clean water. If your item is a cookware or toy, or if you used bleach, be sure to wash it with soap as well. And that's it! Your plastic should now be looking much whiter. If any yellow stains remain, simply repeat the process.

Use vinegar
Vinegar can be used to whiten old plastic items from the 1950s. To do this, you will need to create a mixture of equal parts warm water and distilled white vinegar or cleaning vinegar. Place the plastic item in the mixture and leave it to soak for at least 24 hours. After this, pour out the mixture, wash the container with hot soapy water, and rinse with warm water.
Alternatively, you can dilute vinegar and use it to dampen a melamine sponge. Scrub the stained area of the plastic item with the sponge, then rinse and dry the item.
Another method is to add a tablespoon of detergent, two cups of vinegar, and some water to your sink. Allow the plastic items to soak in this mixture for 15-30 minutes, then use a bristle brush to scrub them. Rinse the items with water and dry them.
You can also try submerging the plastic item in vinegar. If the item is too big to submerge, scrub it with a paste made from vinegar and baking soda.
For electronics or old game consoles, you can wet a Magic Eraser with vinegar, wring it out, and scrub the plastic with it. Dip and wring out the eraser as needed. Continue to scrub the plastic, then wipe it down with a dry towel.

Apply lemon juice
To whiten old plastic from the 1950s, one method that can be used is the application of lemon juice. This method is known for being safe and gentle on plastic, leaving behind a fresh scent.
To begin the process of whitening old plastic with lemon juice, start by pouring lemon juice into a container. The amount of lemon juice required will depend on the size of the plastic item being treated. Ensure that you have enough lemon juice to thoroughly cover the surface of the plastic. If you are working with a lemon that has been cut in half, simply rub the lemon onto the plastic to apply the juice directly. Make sure to cover all the stains and yellowed areas.
After applying the lemon juice, the plastic item should be placed in direct sunlight. The UV rays from the sun will work in combination with the lemon juice to help remove the yellow stains. The amount of time the plastic needs to be left in the sun can vary. Some sources recommend allowing the plastic to soak in the sun for at least an hour, while others suggest a few hours or even an entire day. It is important to monitor the progress and adjust the duration as needed.
Once the plastic has had sufficient time to soak in the sun, use a brush to scrub off any remaining residue. A soft-bristled brush can help gently remove any stubborn stains. After brushing, rinse the plastic item with water to remove any leftover lemon juice and residue. Finally, dry the plastic thoroughly.
It is important to note that the lemon juice method is most effective for small items and may not produce the desired results for larger plastic items. Additionally, this method may not be suitable for plastic items that cannot get wet, such as certain electronic devices or old game consoles. For such items, alternative whitening methods, like using a magic eraser, might be more appropriate.

Try baking soda
If you want to whiten old plastic from the 1950s, one method you can try is using baking soda. This is a natural, gentle abrasive that can help remove light staining from plastic.
To use this method, start by mixing baking soda and water to form a paste. You can do this by pouring some baking soda into a small cup or container and slowly adding water while mixing. Adjust the amount of water until the paste reaches your desired thickness. If you're having trouble getting the right consistency, a good rule of thumb is to mix 2 tablespoons of baking soda with 1 teaspoon of water.
Once you have your paste, use a sponge or paper towel to rub it into the stained areas of the plastic. Make sure to press firmly so that the paste gets inside the tiny pores of the plastic. Let the paste sit for a while—some sources recommend at least a few hours, while others suggest leaving it for a full day. This will give the paste time to work on the stains.
After letting the paste sit, dampen your sponge and gently scrub the plastic. Then, wash the plastic with hot, soapy water and rinse it well. If needed, you can repeat the process until the stains are removed.
For items that can't be scrubbed, you can try spraying them with a mixture of water and baking soda paste. Alternatively, you can try combining the baking soda paste with other whitening agents, such as peroxide or lemon juice, for a more powerful cleaning solution.
Using baking soda is a simple and effective way to remove light stains from old plastic, but for heavier stains, you may need to combine it with other methods or try a different approach altogether.

Sunlight and UV light
Leaving plastic items out in the sun is a simple and natural way to whiten and brighten them. The sun's UV rays can act as a natural bleaching agent, helping to lift stains and discoloration from plastic items. This method is particularly effective for older plastics, as the sun's rays can help to break down the yellowing and discoloration caused by years of exposure to light, heat, and air. Here's how you can use sunlight and UV light to your advantage:
Exposing plastic items to direct sunlight is the most basic and easily accessible method. Place your plastic items in a sunny spot, ensuring they are in direct sunlight and not shaded by other objects. The intensity of the sunlight will depend on your location and the time of year, but generally, the brighter the sunlight, the better. Aim for a few hours of direct sunlight each day, and leave the item out for several days or weeks, depending on the severity of the discoloration. You may want to rotate the item regularly to ensure even exposure and prevent uneven bleaching.
For more controlled and concentrated UV exposure, you can use a UV light source. Special UV lamps are available for this purpose, emitting UV-A, UV-B, or a combination of both types of rays. Place the lamp so that it shines directly on the plastic item, and leave it on for a predetermined amount of time, usually around 15-30 minutes at a time. Be cautious and follow safety instructions when using UV lamps, as prolonged exposure to UV rays can be harmful.
The sun's UV rays work to break down the chemical bonds in the discolored areas of the plastic, effectively bleaching it. This process can take time, depending on the severity of the staining and the intensity of the UV light source. Regular and consistent exposure is key to achieving noticeable results. Additionally, some modern plastics may be more responsive to this treatment than others, so it is important to test a small area first if possible.
Finally, while sunlight and UV light are effective whitening tools, they can also be drying. Prolonged exposure to UV rays can make plastic brittle over time, so it is important to monitor the progress and condition of your plastic items. After whitening, be sure to treat the plastic with a conditioner or oil to restore moisture and prevent cracking or further discoloration. With the right approach, sunlight and UV light can be a powerful tool to bring new life to old plastic items.
