Black plastic on cars is prone to fading and discolouration over time. The sun's UV rays are the main cause of this, as they dehydrate and degrade the plastic. This process is accelerated by environmental contaminants like road salt, dirt, and grime. Luckily, there are several ways to restore black plastic trim on cars. One popular method is to use a heat gun to draw out the natural oils in the plastic, but this is only a temporary solution. Another option is to use a high-quality trim restorer, which provides a more effective and long-lasting result. For a quick fix, household items like olive oil or WD-40 can also be used to temporarily darken and add shine to the plastic.

What You'll Learn
Clean the plastic trim thoroughly to remove dirt and grime
To revive black plastic on a car, it is important to start with a clean surface. This is because dirt and grime can accelerate the degradation of plastic trim. Therefore, it is crucial to clean the plastic trim thoroughly before attempting to restore it.
Begin by washing the plastic trim with soap and warm water. Use a microfiber cloth to gently wipe away any dirt, grime, or other contaminants. Microfiber cloths are ideal for this task as they are effective at picking up and retaining dirt particles. Ensure that you clean all crevices and corners of the trim, as dirt can accumulate in these areas.
After washing the trim, dry it off with a clean towel. It is important to remove all moisture before moving on to the next step of the restoration process. Once the trim is completely dry, you can proceed with confidence, knowing that you have prepared the surface properly.
If your trim has been affected by UV rays, you may notice discoloration or fading. This is because UV rays dehydrate and degrade the plastic on a molecular level. By thoroughly cleaning and preparing the surface, you are taking the necessary steps to restore the trim's original deep black finish.

Apply heat to the plastic to draw out the oils
To restore black plastic on a car, you can use a heat gun to draw out the oils from the plastic. This method is primarily suitable for car trims and bumpers. It is important to note that this is not a long-lasting solution, as the plastic will eventually fade again, and after several treatments, it will no longer have enough natural oils to be drawn out through heating.
Before applying heat, it is crucial to clean and dry the plastic surface. Use soap and water to wash the plastic, removing as much debris as possible. Then, dry it off with a towel. This step is essential because using a heat gun on a dirty plastic surface can burn in any dirt or stains.
When using a heat gun, be sure to cover nearby non-plastic objects with a flame-resistant tarp. Heat guns can warp or discolour the surfaces of non-plastic items. Hold the heat gun several inches away from the plastic surface and move it in small circles around the discoloured area. Avoid keeping the heat gun in one place for too long to prevent burning the plastic or causing uneven discolouration.
The heat from the gun will draw out the natural oils in the black plastic and restore its lustre. This process, known as flame polishing, involves melting the plastic's surface just enough to smooth it out and give it a fresh, polished look.
While this method can effectively restore the appearance of black plastic on a car, it is important to use it with caution and follow the necessary safety precautions.

Treat the plastic with olive oil, WD-40, or a restorer product
One way to restore black plastic on a car is to treat it with olive oil, WD-40, or a restorer product.
Olive Oil
To treat black plastic with olive oil, start by washing and drying the plastic surface with soap and warm water. Then, pour a coin-sized amount of olive oil onto a washcloth or paper towel, and rub it into the plastic. After a few minutes, buff the plastic with a dry cloth to remove any excess oil. If this process does not restore the plastic, you can spray it with black paint, but be sure to use a primer first.
WD-40
Some car owners have reported success using WD-40 to remove wax buildup and restore black plastic trim. However, it is unclear whether WD-40 actually removes the wax or simply covers it up.
Restorer Product
There are many restorer products available for black plastic trim, such as Solution Finish Trim Restorer and Solution Finish Over The Top Plastic Sealer. These products can restore and protect black plastic trim, and some also offer UV protection. When using a restorer product, always read the instructions carefully and follow any safety precautions. For example, Solution Finish can stain clothing and skin, so it is recommended to wear gloves and eye protection.

Apply UV protectant to maintain results
To maintain the results of your black plastic restoration, it is important to apply a UV protectant. This will help prevent sun damage and maintain the deep black finish. There are a variety of products available for this purpose, such as UV-resistant trim shine, plastic sealant, or a product specifically designed to protect against harmful UV rays, like the Solution Finish Over The Top Plastic Sealer.
UV rays from sunlight are the main culprit behind the degradation of black plastic on cars. These rays dehydrate and break down the plastic on a molecular level, causing it to lose its colour and become brittle. By applying a UV protectant, you can create a barrier that shields the plastic from these harmful rays, helping to maintain its appearance and prolong its lifespan.
It is recommended to apply the UV protectant regularly, especially if the car is exposed to direct sunlight for prolonged periods. Parking in a garage or shaded area can also help minimise sun damage. Additionally, it is important to avoid harsh chemicals and automatic car washes, as these can strip away protective coatings and accelerate fading.
When using a UV protectant, always follow the manufacturer's instructions for the best results. Some products may require multiple coats, while others might need time to dry before the treated area can be washed. It is also important to ensure that the plastic surface is clean and dry before applying any protectant, as this will ensure better adhesion and prevent contaminants from getting sealed in.
By taking these proactive measures, you can effectively maintain the restored condition of your car's black plastic trim, preserving its deep black finish and protecting it from the damaging effects of UV rays.

Re-treat the plastic regularly, especially if parked under the sun
To keep your car's black plastic trim looking its best, regular retreatment is necessary, especially if the car is often parked under the sun. Sunlight is the main culprit behind the fading of black plastic, with UV rays dehydrating and degrading the plastic on a molecular level. Therefore, it is important to take preventive measures to ensure your car's plastic trim maintains its deep black finish.
If you are using a heat gun to restore the plastic, it is recommended to retreat the plastic with olive oil, WD-40, or a trim restoration product after heating. This will enhance the protection of the plastic against sun damage. However, the heat gun method is not a permanent solution, as the plastic will eventually deplete its natural oils, leading to discoloration.
To maintain the results of your restoration efforts, you should re-treat the black plastic exterior trim regularly. It is suggested to do this before the start of each season or at least once a month if your car is frequently parked under direct sunlight. This will help shield your car's plastic trim from UV damage and keep it looking new.
Additionally, you can apply a UV protectant or plastic sealant to provide extra protection against sun damage. These products act as a barrier, safeguarding the plastic from the harmful effects of UV rays. By regularly re-treating the plastic and using protective products, you can effectively prolong the life of your car's black plastic trim and maintain its deep black appearance.
