What You'll Learn

Clean trim with a towel and cleaning solution
To revive plastic car trim, cleaning the trim with a towel and a cleaning solution is an important first step. This will ensure that the trim is free of dirt and grime before applying any treatment products.
Firstly, park your vehicle in a sunny spot. This will allow the plastic trim to heat up and soften, making it easier to clean. It is important to note that direct sunlight can cause oxidation and disintegration of the plastic surface over time, so this step should be done with caution.
Next, gather your supplies. You will need a clean towel, a cleaning solution, and a plastic brush. The towel should be made of a soft, absorbent material such as microfiber. It is important to ensure that the towel is clean to avoid scratching the plastic surface.
For the cleaning solution, you can use a dedicated plastic trim cleaner or a mild detergent mixed with water. Some popular plastic trim cleaners include Mothers Back to Black Heavy Duty Trim Cleaner and Meguiar's Ultimate Black. These products not only clean but also help restore the colour and shine of the plastic trim.
Once you have your supplies, start by spraying or applying the cleaning solution generously to the trim. If using a spray, ensure that you cover all areas of the trim evenly. Then, take your towel and gently wipe down the trim, removing any dirt, grime, or residue. For stubborn areas, use the plastic brush to gently scrub the surface. Rinse the towel frequently with water to avoid transferring dirt back onto the trim.
Finally, allow the trim to air dry or use a second clean towel to gently pat the surface dry. Ensure that all cleaning solution residue is removed.
This cleaning process will prepare the plastic trim for further treatment, such as applying a trim restorer or sealant, and help maintain the overall appearance of your vehicle.

Use a heat gun to restore sheen
Using a heat gun is a popular method to restore sheen to plastic car trim. It is a straightforward yet effective approach. The heat gun breaks down the surface pigment of plastic, allowing the chemical bonds between the polymers to realign. The polymers then cool, leaving the surface glossy and wet.
However, it is important to exercise caution when using a heat gun as too much heat can melt the surface of the plastic trim. The heat gun must be held between four to six inches away from the surface for optimum results. It is also important to ensure that the plastic trim is thoroughly cleaned before applying the heat gun. This can be done by using soapy water to remove surface grime, dust, and dirt, and then wiping it dry with a microfiber towel.
There are several heat guns in the market that can be used for this purpose. The SEEKONE Heat Gun, for example, allows you to adjust the temperature and includes four nozzles to control the flow of heat. The CRAFTSMAN Heat Gun is another good option, with a long cord that is useful when working on different parts of the car.
While the heat gun method is effective, it is not a permanent solution. The heat gun draws out the oils within the plastic, and these oils can eventually dry out, causing the trim to turn grey again. Additionally, the heat from the gun can be harmful to painted or glass surfaces, so it is important to keep the gun away from these areas.

Prevent oxidation with UV protectants
Plastic car trim can be restored to its original colour by using a heat gun, but this method is not permanent, and the trim will eventually fade again. The best way to prevent fading and oxidation is to protect the trim before it fades.
Using a premium protectant, treat the plastic, rubber, or vinyl areas of your vehicle while they are still undamaged and unfaded. This ensures these pieces are protected from the elements and harsh ultraviolet rays emitted by the sun, which will keep them black for much longer.
There are several products on the market that can help prevent oxidation with UV protectants. One such product is 303 Protectant, which can be used on everything from trim to plastic and has been proven to work. Another option is Turtle Wax Ice with UV Protectant, a clear spray-on wax that works well in hot sun. Plexus is another good product for plastic.
One user on a forum recommends using pure silicone on rubber seals and 303 on trim. They also mention that they used to use ArmorAll, which was widely used by people selling their cars, as it made them look brand new.
Another product that can be used to prevent oxidation with UV protectants is Meguiar's Ultimate Black Plastic Restorer, which is one of the highest-rated and most popular items on Amazon. It is designed to restore all exterior plastic, vinyl, and rubber trim, including bumpers, moldings, door handles, and rearview mirror housings. The product uses an advanced hybrid polymer technology that seals non-porous surfaces with UV protection, allowing it to significantly outlast conventional protectants and trim care products.

Use a plastic trim restorer
Plastic trim restorers are a great way to revive your car's trim and make it look new again. They are designed to restore and renew plastic, making it look shiny and black. The best part? They require almost no effort and very little elbow grease. You can purchase a can or bottle of plastic trim restorer from your local auto parts shop or online.
There are many different plastic trim restorers available on the market, and it's important to choose one that is high quality and will last a long time. CarGuy's Plastic Restorer is a popular option that is formulated to restore and renew plastic, rubber, or vinyl. It features patented additives to boost longevity and is designed to leave a finish that is completely dry to the touch, with a durable UV guard to protect against harmful UV rays. It is also environmentally safe and does not contain any harmful chemicals.
Another highly recommended product is Solution Finish Trim Restorer, which actually works to fix the damaged plastic, not just dress it. For best results, clean the plastic trim with isopropyl alcohol to ensure there is no residue, only bare plastic. Then, use a microfiber or foam applicator to apply the Solution Finish. Wipe off any excess product with a clean towel and let it dry for at least 6 hours. After the first application, your trim will stay black and look new for approximately 8 months or more.
If you're looking for a more budget-friendly option, you can try using olive oil, WD-40, or even canola oil on a rag. Simply rub the oil onto the faded areas, let it soak for 5 to 10 minutes, and then buff the surface with a dry towel. Keep in mind that this method will require more frequent reapplication, as the finish will fade after repeated washings or weather exposure.
While some people recommend using a heat gun or blow torch to restore plastic trim, this method can actually damage the plastic and make it warp or turn grey and dull. It is important to be cautious when using heat on plastic, as it can make the trim fade faster and weaken the material.

Repaint the trim
Repainting the trim is a simple and permanent solution to restoring plastic car trim. It is important to choose a good trim paint. Before painting, clean the trim to remove any dirt or grime that may affect the restoration process. You can use isopropyl alcohol for this, ensuring there is no residue, only bare plastic. Next, tape off the surrounding areas, such as paint or glass, to avoid smudging on other surfaces. Then, apply a primer if needed. Carefully apply the paint, choosing a finish that suits your preference, such as glossy or matte. You can also choose from different colours, with black being a popular choice, or a subtle grey colour that professionals tend to lean towards. Finally, seal the paint with a clear coat for a glossy finish.
There are various products available for restoring plastic car trim. One option is to use a plastic trim restorer, which is easy to apply and can be purchased from auto parts shops or online stores. These products are typically priced at around $15 to $40 per bottle. Another option is to use linseed oil, a homemade remedy where you pour the oil onto a clean white cloth, rub it on the plastic, and allow it to dry. This will "moisturize" the surface and hide the oxidation. However, this procedure will need to be repeated over time as the linseed oil wears off.
It is worth noting that heat guns can be used to restore plastic trim by drawing out embedded oils, but they can be harmful to painted or glass surfaces, and there is a risk of damaging the paint if not used carefully. Additionally, repeated use of a heat gun or torching can further damage the plastic and lead to costly replacements. Therefore, repainting the trim provides a more permanent solution without the risks associated with heat treatment.
