Sun exposure can cause plastic to fade, discolour, crack, and lose its structural integrity. This is due to the ultraviolet (UV) rays in sunlight, which break down the chemical bonds in plastic, drying out the oils within and damaging the material at a molecular level. Fortunately, there are several methods to restore sun-damaged plastic, including the use of hydrogen peroxide, heat guns, and paint.

Use hydrogen peroxide to reverse sun damage
Sun-darkened plastic is a common problem, especially for car owners. The sun's ultraviolet (UV) rays break down the chemical bonds in plastic, causing it to fade, discolour, become brittle, and lose its structural integrity. This process happens slowly but surely, damaging the plastic at a molecular level.
One way to reverse sun damage on plastic is to use hydrogen peroxide. Hydrogen peroxide is an organic compound consisting of two hydrogen (H) atoms and two oxygen (O) atoms, written as H2O2. It is available in various strengths, typically between 3% and 35%. For reversing sun damage on plastic, a 12% solution is ideal. Stronger solutions can be dangerous if not handled or stored properly.
Before applying hydrogen peroxide, it is important to clean the plastic thoroughly with rubbing alcohol or another cleaner to remove dirt, dust, or other debris that may cause streaking and spots. If the item is small, such as a transistor radio case, it can be submerged in the hydrogen peroxide liquid. For larger items, a cream or paste can be applied liberally with a paintbrush or old toothbrush.
After applying hydrogen peroxide, the plastic item should be exposed to strong, even UV light. One way to do this is to place the item in direct sunlight for about four hours. It is important to rotate the item every hour so that the sunlight hits the discoloured area evenly. Alternatively, an indoor setup with a UV LED light source can be used, providing more control over the UV exposure.
It is important to note that hydrogen peroxide will only work on white or grey plastic products and should not be used on metal items, as it will damage them. Additionally, while sunlight can reverse sun damage on plastic, it can also cause melting or distortion, so caution should be exercised.

Apply hair cream with hydrogen peroxide to discoloured sections
If you want to use hair cream with hydrogen peroxide to lighten sun-darkened plastic, there are a few things to keep in mind. Firstly, hydrogen peroxide is generally safe to use on hair and skin, but it can cause skin, lung, and eye irritation, so it's important to be cautious when handling it. It's also important to start with clean and healthy hair to achieve the best results. Make sure your hair is free of any dirt or product residue, and consider using a natural shampoo and conditioner before applying the hydrogen peroxide.
When applying the hair cream with hydrogen peroxide, section your hair into smaller parts using clips to ensure that every strand is covered. You can use a cotton ball or a spray bottle to apply the cream, making sure to cover the discoloured sections evenly. If you have thin or fine hair, be extra cautious as peroxide can easily spread and lighten your hair more than desired. Leave the cream on for a few minutes, checking periodically to see if it has reached your desired colour. You can leave it on for up to 30 minutes, but it's recommended to rinse it out with cold water as soon as you're happy with the colour.
After rinsing, apply a deep conditioner to your hair to reduce the risk of damage to the hair cuticle. Massage it into your scalp to address any dryness or irritation caused by the peroxide. Then, rinse your hair with cool water and allow it to air dry. If you want to lighten your hair further, you can repeat this process, but keep in mind that oxidative dyes like hydrogen peroxide can cause oxidative stress, leading to hair ageing and potential hair loss.
To use this method for lightening sun-darkened plastic, you would need to apply the hair cream with hydrogen peroxide to the discoloured sections of the plastic item. Follow a similar process as you would for hair, but instead of rinsing, you can wipe off the cream with a damp cloth before it dries to avoid scratching the plastic. Seal the plastic item in a clear plastic bag and place it in direct sunlight for about four hours. The sunlight, in combination with the hydrogen peroxide, will help reverse the sun damage. Remember to rotate the bag every hour to ensure even lightening, and always handle the plastic with care to avoid any scratches or further damage.

Prevent sun damage with commercial plastic conditioning products
Sunlight can wreak havoc on plastic, causing it to fade, discolour, crack, and lose its structural integrity. This is because the sun's ultraviolet (UV) rays break down the chemical bonds in plastic polymers, resulting in a process known as photodegradation. To prevent sun damage to your plastic items, you can use commercial plastic conditioning products. Here are some tips to protect your plastic belongings:
Choose the Right Plastic
Start by selecting plastic items made from UV-resistant materials. Different types of plastic have varying degrees of UV resistance. Acrylic, for instance, is inherently UV-resistant, suffering minimal degradation over time. Polycarbonate is another option that offers relative UV resistance, along with its renowned strength and durability.
Apply Commercial Plastic Conditioners
To enhance the UV resistance of your plastic items, use commercial plastic conditioning products. These conditioners are designed to protect plastic from UV rays and prevent discolouration and cracking. Apply a coin-sized drop of conditioner to the plastic surface, using more as needed to cover the entire area. Buff the conditioner into the plastic using a soft, clean microfiber cloth in circular motions until it is no longer visible. Make sure to wipe away any excess conditioner after it dries.
Regular Maintenance
Maintain your plastic items by regularly cleaning and polishing them. Wash the plastic surface with lukewarm water and a microfiber cloth to remove any dirt, dust, or debris. For tough stains, create a mixture of liquid laundry detergent and warm water. Remember to dry the surface thoroughly before applying any conditioner.
Protect Outdoor Items
If you have outdoor plastic items, such as furniture or pool accessories, they are particularly vulnerable to sun damage. Use products like 303 Aerospace Protectant to shield exposed plastic surfaces from UV rays. This protectant is suitable for various materials, including plastic, rubber, fiberglass, and vinyl. By applying this protectant, you can maintain the longevity and appearance of your outdoor items.
Consider Additional Measures
In addition to commercial conditioners, you can employ other strategies to limit sun exposure. Store your plastic items indoors or in shaded areas when not in use. If possible, cover them with UV-resistant fabrics or materials to provide an extra layer of protection from direct sunlight.

Buff out scratches with a cloth and buffing product
Sun-darkened plastic can be lightened with hydrogen peroxide, which can reverse the damage, but only on white or grey products. Another method is to seal the item in a clear plastic bag and leave it in direct sunlight for four hours, ensuring that the sun-damaged area is exposed. The sunlight can reverse the damage as long as the item is coated in hydrogen peroxide cream.
If your plastic item has scratches, you can buff them out with a cloth and a buffing product. First, clean the plastic surface thoroughly with warm water and a few drops of dish soap, or a small amount of rubbing alcohol applied with a clean cloth. This will ensure that loose debris doesn't further scratch the plastic.
Next, get a buffing product designed for plastic. Place a coin-sized amount on a cloth rag and buff the scratch using circular motions. Be careful not to scrub the area, as this will wear down the plastic. Buffing products come in varying strengths, so choose one that is suitable for the depth of your scratches. If you are dealing with deeper scratches, you may need to use progressively finer-grit sandpaper, up to around 2,000 grit, until the scratch disappears.
After buffing, wipe off the product with a microfiber cloth, removing any residue before it dries. Finally, spray on a plastic polish to restore shine to the surface.

Wash plastic with a mixture of laundry detergent and warm water
To lighten sun-darkened plastic, one of the suggested methods involves washing the plastic with a mixture of laundry detergent and warm water. This method is particularly effective for removing tough stains.
First, you need to mix the cleaning solution. For this method, you will need 0.5 fl oz (15 mL) of liquid laundry detergent and 16 fl oz (470 mL) of warm water. Mix these together thoroughly.
Next, you will need to apply the solution to the plastic. You can use a cloth or sponge to do this, ensuring that you work the solution into any affected areas. If the plastic is heavily soiled or stained, you may need to agitate the surface with a soft-bristled brush to help loosen any dirt or debris.
After applying the detergent mixture, you should rinse the plastic thoroughly with clean, warm water to remove any residual detergent. Ensure that you direct the rinse water away from any areas where it could cause damage, such as gardens or water features.
Finally, dry the plastic surface with a clean, soft cloth. It is important to ensure that the plastic is completely dry before using it or storing it away. You can also apply a plastic conditioner after washing to help protect the surface and restore its shine.
This method is a simple and effective way to clean and lighten sun-darkened plastic. However, if the discolouration is severe, you may need to repeat the process several times or consider using alternative methods, such as hydrogen peroxide treatments or plastic polishing products.
