Take a glance at any car, and you’ll see the black plastic cladding that protects the edges and edges. Over time this trim can oxidize, creating an aged effect. The black plastic trim details of your car can range from the typical window, and sunroof trims to the more hardy applications seen on off-road-ready SUVs. Recent trends have seen the addition of more and more black plastic trim to give the appearance of a rugged and off-road-ready vehicle. With these additions comes more maintenance and, ultimately, prevention from the effects of UV rays, contaminants from the road, and harsh weather off-road-ready conditions.

Tips On How To Clean Black Plastic Trim On Your Car
The use of black plastic trim on the exterior of cars as a means of protection is nothing new and is mainly a function of cost for manufacturers. It increases the design elements without worrying about bending steel to suit the same purpose.
Why Does The Black Plastic Trim On Cars Fade
Black plastic trim is found on many components of your car’s exterior.
Black trim can be described as any black plastic material lining the outer edges of the care and can be found in multiple places such as:
- Door handles
- Roof racks
- Sunroof trim
- Mud Flaps
- Window rubber gaskets
- Panel trim pieces
While plastic is now widely used on the exterior of cars, it does have its limitations. These areas are constantly exposed to UV rays, where subsequent fading ensues. In addition, the staining from wax products, harsh weather, and contaminants from the road can all contribute to an unsightly greyish hue to the trim.
So what is happening to cause this change?
When the black plastic trim is heated from the beating sun and regular driving, polymers in the plastic crystallize and appear as a white sheen on the plastic. Plastic also contains oils that degrade from UV exposure from dehydration of the plastic.
What results is a chalky appearance and a brittle feel. If this is already the case for your vehicle, rehabilitation should be done immediately, and prevention protocols added to your regular maintenance schedule.
The Quick Fix
The quick fix options listed below are essentially aesthetic band-aids that are temporary in nature lasting from 3 to 6 weeks. These solutions are well suited for minimal spot damage from gravel marks to localized white scuffs.
This handy household cleaning item is great for many do-it-yourself maintenance projects on your vehicle. To take white scuff marks off of the black plastic trim, just dampen the Magic Eraser sponge with a little water and wipe in a circular motion. Rinse and dry as usual.
To bring the shine up on your black plastic trim in a hurry, try applying a light coat of olive oil. Baby oil and linseed oil can also serve the same purpose.
The oil will sink in and rehydrate the plastic leaving behind a just like new deep black color. While this won’t retain the results as long as a professional trim conditioner, it will do the job in a pinch.
- Wash and dry the surface of the trim.
- Pour a coin-sized amount of olive oil on a soft cloth.
- Massage the oil into the plastic for several minutes to get maximum absorption.
- Buff the plastic with a dry cloth,
- Inspect for residual discoloration; there might be some spots that need additional restoration.
Trim dressing is like wax for our trim. It acts to protect and give a deeper black appearance to road-worn trim. This is generally thought to be a short term weeks-long fix. For longer-term results, a trim restoration product should be used, and the trim dressing applied after.
Solution Finish Black Plastic & Vinyl Plastic Trim Restorer has been noted among many car restorers as a top choice.
The product provides a like-new finish with a formula free of silicone and helps to reduce the dull appearance caused by oxidation and sun damage.
These permanent solutions are suited for overall restoration and by nature, are more time-consuming and intense treatments. In addition, these methods are best suited for overall UV damage causing a grey or dull look to black plastic trim.
A good quality plastic restorer will be absorbed by the plastic allowing it to break down oxidation damage. These products are built to bond with surfaces for long-term results.
In addition, a good dressing or sealant will create a protective layer, preventing future damage. Here are a few of our favorites.

Tips for Restoration
While trim restoration is relatively straightforward when the product directions are followed, there are a few things to keep in mind:
- Clean and dry your vehicle thoroughly before application.
- Consider using a degreaser agent to tackle hard to remove dirt and contaminants that can reduce the effectiveness of restoration products.
- Apply the trim restorer under a covered area to avoid being caught mid-application in foul weather, disrupting the product’s bonding time.
- Make sure the trim is thoroughly cleaned and decontaminated before applying the product.
- Use a small handheld microfiber cloth when possible.
- Tape any areas adjacent to the trim to avoid damage to the paint.
- Take care to apply the product evenly across the trim’s surface to avoid discoloration or inconsistency across the surface.
- Don’t neglect trims for long periods of time. A good maintenance schedule will help to avoid time-consuming restoration projects.
- If you apply a dressing, clean it off periodically. Layering dressings will eventually result in discoloration as the top most layer is not bonded to the plastic.
