While most of your car is made of metal, significant parts of both the interior and exterior rely on plastic components. From bumpers and grilles to side mirrors and trim, plastic is always a part of your car. However, prolonged exposure to sunlight, harsh weather, and road debris can cause these once-deep black trims to fade into a dull, grayish color, making your car look older than it is.
If you’ve noticed the plastic trim losing its original color, the good news is that permanent restoration of the black plastic trim is possible. Whether you prefer professional-grade solutions or simple DIY fixes, there are multiple ways to bring back that deep black finish.
Here are some most effective techniques to clean and restore black plastic trim on the car:
Professional Methods to Restore Black Plastic Trim
Using a Trim Restorer for a Permanent Fix
One of the most effective ways to restore black plastic trim is by using a high-quality trim restorer. Unlike temporary solutions, trim restorers penetrate the plastic’s surface, replenishing lost oils and providing UV protection. Look for a product that offers long-term durability, such as Torque Detail Plastic Restore.
How to Use Trim Restorer
- Clean the trim thoroughly with isopropyl alcohol to remove any residue.
- Use a microfiber applicator to apply the trim restorer evenly.
- Allow the product to absorb for a few minutes before buffing off excess residue.
- Let it cure for at least 6 hours before exposing the trim to moisture.
This method can keep plastic trim looking new for up to a year with proper maintenance.
Heat Gun Method for Oil Redistribution
Applying heat to faded plastic draws out the oils trapped within the material, temporarily restoring its black color.
How to Use Heat Gun to Restore Plastic Trim
- Wash and dry the plastic trim.
- Set the heat gun to a low or medium setting to avoid warping the plastic.
- Move the heat gun in slow, sweeping motions, ensuring even heat distribution.
- Once the trim darkens, apply a UV protectant to maintain the results.
While effective, the heat gun method is not a permanent fix to restore the plastic trim since the natural oils will eventually deplete again.

Household DIY Options to Restore Black Plastic Trim
If you need a quick, budget-friendly fix, some household items can temporarily improve the appearance of faded trim.
Olive Oil or WD-40
Both olive oil and WD-40 can temporarily darken plastic trim and add shine. However, these solutions are short-lived as they wash off easily with rain or car washes. To apply:
- Clean the plastic trim thoroughly to remove dirt and grime.
- Apply a small amount of olive oil or WD-40 onto a clean microfiber towel.
- Rub the towel onto the faded trim in circular motions.
- Buff off any excess product to avoid streaking.
Restoring Trim with Peanut Butter
Yes! Peanut Butter sounds weird but it is a common technique used by car owners to restore plastic trim. Peanut butter contains natural oils that can darken faded trim, but it’s a messy process with a strong scent. If trying this method:
- Apply smooth peanut butter onto a clean microfiber cloth.
- Rub it into the trim in circular motions.
- Let it sit for 5-10 minutes before buffing off with a dry towel.
- Clean the surface with mild soap and water to remove any residue.
Using Paint Thinner for Oxidation Removal
Paint thinner can remove oxidation buildup but should be used cautiously as it may damage plastic if over-applied. To use:
- Dampen a microfiber cloth with a small amount of paint thinner.
- Gently wipe the affected areas in small sections.
- Immediately wipe off excess with a clean, dry towel.
- Apply a UV protectant to prevent further fading.
These DIY methods may provide short-term results but may have long-term effects on your car. We recommend you to get a professional service to prevent future damage.
Why Black Plastic Trim Fades
Plastic trim is made from polymer compounds that contain essential oils. Over time, exposure to UV rays depletes these oils, causing the surface to dry out and lose its deep black finish. Environmental contaminants like road salt, dirt, and grime further accelerate the degradation process, making regular maintenance necessary.
Protecting Restored Trim from Future Fading
Once your trim is restored, taking preventive measures ensures it stays black for as long as possible.
- Apply a UV protectant or plastic sealant to prevent sun damage.
- Shield your car from direct sunlight by using a car cover or parking in a garage or any shaded area.
- Avoid harsh chemicals and automatic car washes that strip protective coatings and accelerate fadings.
- Regularly clean and maintain the trim to extend its lifespan.
Restoring black plastic trim is simple with the right approach. While DIY solutions offer temporary improvements, a high-quality trim restorer provides the most effective and lasting results. Protect your trim with proper maintenance to keep your vehicle looking sharp for years to come.
