Plastic is a vital component of modern cars, used for everything from headlights to bumpers. However, it is susceptible to sun damage, with UV rays causing plastic to fade, discolour, crack, and deteriorate. This can make a car look older than it is. Luckily, there are several ways to restore plastic to its original shine, from using heat guns and olive oil to applying plastic restorers, water-based dressings, and gel treatments.

What You'll Learn
Using a heat gun
Before using a heat gun, it is important to clean the plastic surface with soap and water to remove any dirt or grime. Cover nearby non-plastic objects with a tarp, as the heat gun can warp or discolour their surfaces. During the process, maintain a safe distance from the plastic, and keep the heat gun moving in a slow, circular motion to avoid overheating and discolouration. Stop heating once you achieve the desired result.
It is crucial to understand that the key to success with this method is maintaining control over the heat. Excessive heat can cause the plastic to warp, melt, or become brittle, while insufficient heat will not produce the desired effect. Therefore, this process requires patience and precision, as rushing may result in uneven results or permanent damage to the plastic.
After applying heat, allow the plastic to cool completely before touching or applying any products. For additional protection and shine, you may apply a plastic restorer to seal the surface and protect it from future fading. This step is optional but can help extend the lifespan of the restoration.
The heat gun method is a fast, cost-effective, and efficient way to restore faded plastic trim. However, it is important to note that improper use can lead to melted or damaged plastic. Therefore, it is recommended for those confident in their ability to control the heat and follow the process carefully.

Applying olive oil
Olive oil can be used to restore the shine of plastic surfaces in cars. It is a natural alternative to chemical cleaners and can restore the colour of discoloured plastic.
To use olive oil to restore the shine of plastic in your car, first, wash and dry the plastic surface with soap and warm water. Dry the surface with a towel to ensure that the olive oil will be absorbed properly. Next, pour a coin-sized amount of olive oil onto a cloth. You can use a washcloth or a paper towel. It is important to note that a little goes a long way, and you can always add more later if needed.
Rub the olive oil onto the plastic surface for a few minutes. Then, take a dry washcloth and wipe the plastic in circular motions. Apply heavy pressure as you do so to get rid of the olive oil grease and add an extra shine. If you don't have another cloth, use the part of the first paper towel or washcloth that isn't oily.
Finally, inspect the plastic for any residual discolouration. If you notice any patches that the olive oil didn't restore, try the process again with more oil, directly targeting the stubborn area. For severe fading or discolouration, you may need to resort to other methods, such as using a heat gun or spray painting the plastic.

Using a plastic restorer
Steps to Follow:
- Clean the plastic surface: Wash the plastic trim with a cleaning agent such as isopropyl alcohol to remove any residue and ensure only bare plastic remains.
- Apply the plastic restorer: Use a microfiber applicator or foam applicator to apply the plastic restorer evenly onto the plastic surface. You can use products such as Solution Finish Trim Restorer, Turtle Wax Black in a Flash Trim & Tyre Dressing, Koch Chemie PSS, or Adams Graphene Tire Dressing.
- Wipe off excess product: Use a clean microfiber towel to wipe away any excess restorer from the plastic surface.
- Allow drying time: Let the plastic restorer dry completely. The recommended drying time varies depending on the product used, ranging from 6 hours to 12 hours.
- Inspect the results: After the first application, your plastic trim should regain its original colour and shine. Inspect the trim for any residual discolouration or areas that require additional attention.
- Reapply as needed: For best results, consider applying a second coat of the plastic restorer. This can further enhance and prolong the results.
Additional Tips:
- To extend the life of the treatment, consider using a UV protectant product, such as Solution Finish Over The Top Plastic Sealer, as a topper over the plastic restorer.
- For severe fading or discolouration, you may need to use an alternative method, such as spray painting the plastic trim black.
- Be cautious when using a heat gun method, as it can warp or discolour the plastic if not done carefully.

Cleaning with soap and water
To restore the shine to plastic on your car, one of the easiest methods is to use soap and water to clean the plastic. This is a great start to maintaining black plastic trim. You should use a gentle automotive soap and water to clean the plastic. This will remove dirt, debris, and any residues.
Before you begin, make sure you are wearing gloves to protect your hands. You should also work in a well-ventilated area to avoid inhaling any chemical fumes.
First, wash the plastic trim with soap and warm water. You can use a gentle automotive soap or a strong yet gentle super cleaner like Nonsense All Purpose Cleaner to remove stains, grime, grease, and dirt. Rinse the soap off with water and dry the plastic trim with a towel.
You can then use a water-based dressing like Silk Shine, VRP, Tire Kicker, or Natural Shine to maintain the look of your rejuvenated exterior trim. These products are great for future maintenance and will help to restore the shine to your plastic trim.
It is important to note that you should avoid using too much product as this can lead to a greasy or sticky finish that fails to dry correctly, attracting dust and dirt. Regular washes, polishes, and proper storage are also important to take care of your car, especially if you live in a place with intense summers and winters.

Protecting against UV rays
UV rays can cause significant damage to your car's exterior and interior, including discolouration, cracking, and deterioration of plastic components. Here are some detailed, direct, and instructive tips to protect your car's plastic from UV damage:
Park in the Shade
Park your car in shaded areas whenever possible. This simple yet effective method minimizes direct sun exposure, reducing the impact of UV rays on your vehicle.
Use Sun Shields and Window Tints
Install sun shields or window shades inside your car to reflect UV rays away from the interior. Additionally, consider applying window tints with UV-protective properties, such as ceramic tinting, to block UV rays from entering the car through the glass.
Apply Protective Coatings
Use protective coatings designed to shield your car's exterior and interior surfaces from UV rays. For example, products like CARPRO DLight are plastic coatings with strong UV absorbers and light stabilizers, effectively blocking harmful UVA and UVB rays, preventing discolouration, fading, and cracking.
Maintain Regular Cleaning
Regularly clean your car to remove contaminants such as bird droppings, tree sap, and bug splatter. These contaminants can interact with UV rays, causing indirect sun damage to your car's paintwork and surfaces. The two-bucket washing method is recommended: use one bucket with soap and another with clean water to prevent debris transfer back onto the car's surface.
Choose Paint Protection Films (PPFs)
While expensive, PPFs offer comprehensive protection for your car's paintwork. They shield against UV rays, oxidation, heat, and even physical damage like scratches.
By implementing these measures, you can effectively protect your car's plastic components and other surfaces from the damaging effects of UV rays, maintaining the vehicle's aesthetic appeal and resale value.
