Yellowed plastic is a common issue that can occur due to various factors such as UV light exposure, stains, or simply aging. While it may be tempting to reach for the paintbrush, there are several alternative methods to consider first. For example, you could try cleaning the plastic with a Magic Eraser, or soaking it in a solution of bleach and water. Other methods include using baking soda, white vinegar, or lemon juice. If these methods don't work, you may need to consider painting the plastic. However, it's important to use a plastic-bonding paint, such as Krylon Fusion, to ensure the paint adheres properly and doesn't flake off.

Painting yellow plastic white
If you wish to proceed with painting, it is crucial to choose a paint specifically designed for use on plastic, such as Krylon Fusion or a similar plastic-bonding paint. This ensures that the paint adheres properly to the plastic surface and prevents flaking or an uneven finish.
Before painting, it is essential to clean the plastic surface thoroughly. You can try soaking the plastic in a solution of bleach and water or using a Mr. Clean Magic Eraser to remove any stains or discolouration. Allow the plastic to dry completely before painting.
When painting, follow the instructions on the paint packaging for the best results. Typically, spray paint designed for plastic is the easiest to apply, offering a more uniform finish. Make sure to work in a well-ventilated area and use gloves and eye protection for safety.
With the proper preparation and the right type of paint, you can successfully paint yellow plastic white, restoring its original colour and appearance.

Soaking in bleach water
If you want to restore yellowed plastic to its original white colour, one method is to soak it in a bleach solution. This method can be effective, but it is important to exercise caution when working with bleach. It is recommended to wear gloves when handling bleach and to thoroughly rinse the plastic item after soaking. In addition, it is advised to avoid using bleach on items that will come into contact with food or children's toys, as bleach is toxic if ingested.
To create a bleach solution for soaking, fill a sink or container with water and add bleach. The exact ratio of water to bleach may vary depending on the source, but a common suggestion is to mix eight parts water with one part bleach. Submerge the plastic item in the bleach solution and let it soak until it turns white again. This process may take some time, and it is important to be patient to avoid over-soaking, which could potentially damage the plastic.
After the plastic has soaked and returned to its original white colour, remove it from the bleach solution and dispose of the solution safely. Wash the plastic item with mild soap and water to remove any residual bleach. Rinse the item thoroughly to ensure no bleach remains, as residual bleach can result in a strong chlorine taste. Finally, dry the item and enjoy your freshly whitened plastic!
While soaking plastic in bleach can be effective, it is important to note that bleach can potentially react with plastic and may not be suitable for all types of plastic. Therefore, it is recommended to test the method on a small, inconspicuous area first. Additionally, there are alternative methods for whitening yellowed plastic, such as using baking soda, white vinegar, or a Magic Eraser. These methods may be more suitable for certain items, especially those that will come into contact with food or children.

Using a Mr. Clean Magic Eraser
If you have yellowed plastic that you want to turn white again, there are several methods you can try. You can try cleaning it with a mild solution of soap and water, or try natural methods like lemon juice or vinegar. If that doesn't work, you can try using bleach or baking soda.
If you want to try a cleaning product, Mr. Clean Magic Eraser is a good option. Here's how you can use it:
- Start by wetting the Magic Eraser with water and wringing it out. The eraser should be damp but not soaked.
- Gently scrub the yellowed plastic with the Magic Eraser. Use gentle, circular motions and apply light pressure.
- Rinse or wipe the surface with a damp cloth to remove any residue from the eraser.
- Dry the surface with a soft, absorbent cloth or towel.
- Inspect the results. If the plastic is still yellow, repeat the process, but this time, apply a little more pressure while scrubbing.
It's important to note that while the Magic Eraser is a powerful cleaning tool, it may not always completely remove deep or set-in yellow stains. In some cases, the discolouration may be too severe, and painting may be the only option to restore the plastic to its original colour.
Additionally, the Magic Eraser is abrasive and can scratch delicate surfaces. Always test it on a small, inconspicuous area first to ensure it doesn't damage the plastic. If the plastic surface has a glossy finish, be cautious as the Magic Eraser can dull the sheen.
The Magic Eraser is a versatile tool that can be used on various surfaces, including walls, countertops, appliances, and more. It's an excellent option for removing tough stains and built-up dirt without the need for harsh chemicals.

Applying hair bleach
Before applying hair bleach, it is important to understand the risks involved. Hair bleach can damage your hair by stripping the protective fibres and oils from the hair, making it weaker, thinner, and more vulnerable to dryness and damage. Therefore, it is recommended to seek a skilled professional for an on-scalp lightening application. However, if you choose to apply hair bleach at home, here are some detailed steps to follow:
Preparation:
Before bleaching, proper preparation is essential to minimise damage and achieve the best results. Firstly, determine if your hair is healthy enough to bleach. If your hair is already showing severe signs of damage, such as frizziness, dryness, and breakage, it is advisable to consult a professional colourist. A week before bleaching, minimise the use of hot tools and heat styling. Additionally, skip harsh skincare products a few days before bleaching, as they can increase scalp sensitivity during the process.
Gathering Supplies:
Bleaching hair requires specific supplies, and it is important to have everything ready before starting. You will need bleach powder, a developer, gloves, a barrier cream or Vaseline, a mixing bowl, a whisk, a tinting brush, and plastic wrap. You can purchase a hair bleach kit, which typically includes the formula, gloves, a bowl, and an application brush. However, ensure you read the box carefully to confirm the included items.
Sectioning Hair:
Start by brushing your hair to ensure it is tangle-free. Then, section your hair into quarters, creating a centre part straight back to the nape of your neck. Secure each quarter with clips. Within each quarter, use the tapered end of your applicator to create horizontal parts, dividing the hair into smaller, more manageable sections.
Mixing and Applying Bleach:
Follow the instructions on your bleach powder and developer to determine the correct ratio for mixing. Put on your gloves and mix the bleach and developer in a plastic bowl using a whisk until properly blended. Apply the bleach mixture to your hair, starting at the ends and working your way up, leaving about 1 cm from the roots. Ensure your hair is fully saturated by applying the bleach generously. Cover both sides of each hair section. The backmost and bottommost sections of hair are generally darker and can tolerate extra processing time.
Processing and Rinsing:
Cover your hair with plastic wrap and set a timer to check the processing every 10 minutes. The processing time will depend on your hair colour, desired results, and package directions. Once you achieve your desired shade, rinse the bleach out with cold water and shampoo immediately.
Toning:
If you want to go platinum blonde or neutralise any unwanted brassy or orange tones, you will need to apply toner after bleaching. Use a clean tinting brush to apply the toner in sections, following the same application technique as the bleach. Let the toner sit for about 30 minutes, then rinse it out with cold water until the water runs clear. Use a shampoo designed for bleached hair to ensure all the toner is removed.

Using plastic spray paint
Painting yellow plastic white is a simple task that can be done using plastic spray paint. There are a few steps to follow to ensure the paint adheres well to the plastic surface and that you get a professional-looking finish.
Firstly, it is important to clean the plastic surface thoroughly. If the plastic has turned yellow due to sun exposure, it may not be possible to restore it to its original colour without using chemicals to melt and reform the plastic. However, a cleaning agent such as bleach, baking soda, or white vinegar can be used to whiten the surface. For electronic items, it is recommended to remove the plastic parts and soak them in a water and bleach solution before washing them with mild soap and water.
Once the plastic is clean and dry, it may need to be sanded, especially if it is older plastic with loose paint or other coatings. Use sandpaper to gently smooth the surface, then rinse and wipe the surface with a tack cloth to ensure it is free of debris. Allow the surface to dry completely before painting.
To ensure the paint adheres well to the plastic, it is recommended to use a spray paint that is specifically designed for use on plastic, such as Krylon Fusion All-In-One. These paints often have built-in primer, which helps the paint stick to the plastic surface. If your chosen spray paint does not have a built-in primer, you may need to apply a separate primer before painting.
When you are ready to paint, hold the spray can the recommended distance away from the surface of your project to minimise drips and areas of excess paint. This distance will be outlined on the can. Apply several light coats of paint, waiting 30-60 seconds between each coat, until you are satisfied with the appearance. Always start and finish your spray pattern off the object and release the spray tip at the end of each pass to ensure even coverage. Use a smooth, even sweeping motion and overlap your spray pattern by about one-third with each pass.
Finally, if your painted item will be used outdoors, consider applying a layer of clear, non-yellowing protection to shield the paint from the elements.
