Restore Black Plastic Shine: Tips And Tricks

how to restore shiny black plastic

Black plastic trim on cars is prone to fading and discolouration over time, losing its rich black colour and turning grey or even white. This can be due to exposure to UV rays, contaminants, and oxidation. Luckily, there are several methods to restore faded black plastic trim to its original colour and shine. Some common approaches include using olive oil, heat guns, plastic restorers, sealants, and coatings. It's important to clean the plastic surface thoroughly and protect surrounding areas before beginning the restoration process. While some methods may provide temporary results, others, like plastic restorers and sealants, can offer long-lasting protection and help maintain the visual impact of your vehicle.

Clean the plastic surface

To restore the shine on black plastic, it is important to start with a clean surface. Here are some ways to clean the plastic surface:

Wash with soap and water

Use soap and warm water to wash the plastic surface. This will help remove any dirt, stains, or debris from the surface. It is important to ensure that the plastic is thoroughly cleaned to ensure that any restoration product applied afterward can be absorbed effectively.

Dry with a towel

After washing, use a clean towel to dry off the plastic surface. This step is crucial as you do not want the restoration product to slip off a wet surface. Make sure to wipe down the surface gently and thoroughly to avoid leaving any lint or fibers on the plastic.

Remove oxidation

If the black plastic has turned white or gray due to oxidation, it is important to remove as much of the oxidation as possible. You can use a machine or hand scrub with a brush, wash mitt, or other tools to remove the oxidized layer. This step will help restore the original black color of the plastic.

Use isopropyl alcohol

Prior to applying a restoration product, you can use isopropyl alcohol (IPA) to remove any residual cleaners, oils, or silicones from the plastic surface. Apply a small amount of IPA to a microfiber sponge or applicator pad and spread it evenly over the plastic surface. This step will ensure that the restoration product can adhere properly to the plastic.

Choose an inconspicuous area to start

When cleaning and restoring black plastic, it is recommended to start in an inconspicuous area first. This will help you avoid any potential damage or discoloration in a noticeable area. By testing in a small, hidden area, you can ensure that the cleaning and restoration process will not cause any unwanted effects on the plastic.

Use a heat gun

Using a heat gun is an effective way to restore the shine to black plastic items. This method works by slowly breaking down the plastic's molecular composition, allowing the chemical bond to realign as the polymers cool, leaving a wet, glossy surface. The heat opens up the cells and allows the moisture to escape, and also brings out the natural oils in the plastic, restoring its luster.

To use a heat gun, start by covering any nearby non-plastic objects or surfaces with a flame-resistant tarp, as the heat gun can warp or discolour them. Wash the plastic object with soap and water, cleaning away any dirt, waxes or treatments, and dry it off with a towel. This is important, as using a heat gun on a dirty surface can burn in any dirt or stains.

Once the plastic is clean and dry, turn on the heat gun and hold it several inches away from the surface. Move the heat gun in small circles around the discoloured plastic, avoiding leaving it in one place for too long, to keep the colour treatment even and avoid burning the plastic. Aim the tip of the heat gun perpendicular to the surface, adjusting your angle to the contours of the plastic to avoid overheating one area while treating another.

As you move the heat gun around the plastic, it should change to a darker, richer colour. When you've covered the entire surface, turn off the heat gun and inspect the colour. If you're happy with the result, you have finished restoring the object. If the plastic still looks faded or discoloured, you may need to repeat the process or try a different method, such as applying olive oil or painting the object.

It's important to note that using a heat gun on plastic can make it more brittle, and the colour may eventually fade again over time. The longevity of this method depends on the specific plastic's chemical makeup, environment and exposure to sunlight. Regularly using a rejuvenation product may be more effective in the long term.

Apply olive oil

If you're looking to restore the shine of black plastic, olive oil can be an effective solution. Here's a detailed guide on how to apply olive oil to achieve that shiny finish:

Cleaning and Preparation:

Before applying olive oil, it's important to start with a clean surface. Wash the plastic with soap and warm water to remove any dirt, dust, or grime. Ensure that you clean thoroughly, as any remaining contaminants can get burned into the plastic during the restoration process. Once cleaned, dry the plastic surface with a towel. This step is crucial because the olive oil will absorb better into a clean and dry surface.

Applying Olive Oil:

Take a coin-sized amount of olive oil (preferably extra virgin olive oil) and pour it onto a dry microfiber towel or washcloth. You can also use a paper towel, but a microfiber towel is preferred for more effective absorption. Gently rub the oiled towel on the plastic using small, circular motions. Focus on the faded or discoloured areas, ensuring that the oil covers them evenly. Don't be afraid to add more oil if needed, but remember that a little goes a long way.

Buffing and Shining:

After applying the olive oil, let the plastic absorb it for about 5 to 10 minutes. Then, grab a separate dry towel and buff the surface lightly using rapid circular motions. This process will help remove excess oil and grease while adding an extra shine to the plastic. If needed, turn the towel over and give it a final buff to ensure an even finish.

Post-Treatment Care:

While olive oil can effectively restore the shine of black plastic, it may not provide long-term protection. To maintain the finish, reapply olive oil at least weekly. Additionally, protect the treated plastic from prolonged exposure to harsh weather conditions or repeated washings, as these factors can cause the shine to fade over time.

Alternative Treatments:

If you're looking for alternative treatments, you can explore using a heat gun or purchasing a black plastic trim moisturizer. Heat guns can help draw out the natural oils in the plastic, but they may not be a long-lasting solution and require careful handling. Black plastic trim moisturizers, on the other hand, can be applied similarly to olive oil and are specifically designed to restore car trims.

Try a plastic restorer

If you're looking to restore the shine on your faded black plastic, a dedicated plastic restorer could be the answer. Black plastic trim, especially on cars, is prone to fading and discolouration over time due to exposure to UV rays and contaminants. Using a plastic restorer is an easy and cost-effective way to bring back that deep black colour and shine, enhancing the overall appearance of your vehicle.

There are various plastic restorers available on the market, such as Meguiar's Ultimate Black Plastic Restorer, which is specially formulated for non-painted exterior trim and plastic. It delivers a rich, dark shine and outstanding UV protection, helping to prevent aging, fading, and discolouration. Its fast-drying, non-greasy formula makes it easy to use and ensures long-lasting protection. Another option is Solution Finish Trim Restorer, which can be applied using a microfiber or foam applicator. After allowing the plastic to dry for 6 hours, the trim will stay black and look new for approximately 8 months or longer with a second application.

For added protection against UV rays, you can use a finishing product like Torque Detail Ceramic Spray or Solution Finish Over The Top Plastic Sealer. These products create an invisible, durable layer on top of the restored plastic, protecting it from fading and deterioration. They are designed to be easily applied at home and can enhance and extend the life of the treatment.

When using a plastic restorer, it is important to follow the instructions carefully. Make sure to clean and dry the plastic surface before application and always wear gloves and eye protection. Additionally, some products should not be used on painted or glass surfaces, so be sure to wipe off any excess immediately if it comes into contact with these areas.

By using a plastic restorer, you can effectively restore the shine and colour of your faded black plastic, improving the overall aesthetics and giving it a like-new finish.

Seal with a UV protectant

Black plastic, especially car trims and bumpers, is prone to fading and discolouration over time. To restore black plastic, you can use olive oil or a heat gun on the faded area. However, to prevent the plastic from fading again, it is important to seal it with a UV protectant.

UV protectants form a barrier against the UV rays that cause plastics to fade. There are various products available that can be used to seal black plastic and protect it from UV damage. For example, 303 Aerospace Protectant provides superior UV protection, prevents fading and cracking, and repels dust, lint, and staining. It also restores lost colour and luster. This product is available in 10oz and 32oz sizes.

Another option is to use a ceramic spray, such as Torque Detail Ceramic Spray, which builds an invisible and durable ceramic layer on top of the plastic finish. This not only gives it an ultra-premium shine that lasts for up to 12 months but also protects against UV rays and road contaminants.

If you are looking for a more natural solution, you can try using olive oil. Olive oil can restore black plastic's natural colour and add shine. However, it may not be as effective as the other UV protectant products mentioned above.

It is important to note that some UV protectants are designed specifically for certain types of materials, such as vinyl, rubber, or plastic. Make sure to read the product labels and instructions carefully before use.
