Black Car Plastic: Polishing Tips And Tricks

how to polish black car plastic

Black plastic car trim is prone to fading and discolouration over time, and can be a challenge to restore. There are several methods to restore black plastic trim, ranging from easy to advanced. One temporary solution is to use a heat gun to bring out the natural oils in the plastic and restore its lustre. Another option is to use a plastic restorer, such as Solution Finish, which can be applied with a microfiber or foam applicator. For a more natural approach, olive oil or peanut butter can be applied to the plastic's surface to restore its shine. Additionally, products like Meguiar's PlastX and Blackfire Wax Remover have been recommended by car enthusiasts for removing scratches and restoring the trim.

Use a heat gun to restore natural oils

Using a heat gun is a temporary solution to restore the natural oils in black car plastic. Heat guns increase the heat and draw out the oils from beneath the surface of the plastic to restore its colour and shine.

Before using a heat gun, it is important to clean and dry the plastic surface. Wash the object with soap and water, removing as much debris as possible. Dry it off with a towel before applying heat. Cover any nearby non-plastic objects or areas you do not want to heat with a flame-resistant tarp, as heat guns can warp or discolour non-plastic surfaces.

When using the heat gun, hold it several inches away from the plastic surface and move it in small circles around the discoloured area. Avoid leaving the heat gun in one place for too long to prevent burning the plastic. As you move the heat gun, the plastic should change to a darker, richer colour. Turn off the heat gun and inspect the new colour.

It is important to note that this method is not a long-lasting solution. The treatment's duration depends on the environment and exposure, ranging from a few weeks to a year or more. Over time, the plastic may fade again, and after several treatments, it will no longer have enough natural oils to restore. Additionally, there is a risk of overheating and melting the plastic, causing irreparable damage.

If you are looking for a more permanent solution, consider using a plastic restorer or a black plastic trim moisturiser specifically designed for cars. These products can help protect and restore black car plastic, improving the appearance of your vehicle.

Try olive oil or a plastic moisturiser

Black plastic, especially car trims and bumpers, is prone to fading and discolouration over time. To restore black plastic, you can try olive oil or a plastic moisturiser.

Olive Oil

Olive oil can restore black plastic's natural colour, clearing up any faded or discoloured areas. Wash and dry the plastic's surface before applying olive oil. Pour a coin-sized amount of olive oil on a cloth and rub it into the plastic. After rubbing the plastic for a few minutes, buff it with a dry cloth to remove any excess oil.

Plastic Moisturiser

If you would prefer to use a product made specifically for cars, you can use a black plastic trim moisturiser. Like olive oil, black plastic moisturisers restore car trims and bumpers by adding moisture to their surface. You can buy car trim moisturisers at most automotive stores. Read the instructions carefully before applying the product.

Other Options

Other options to restore black plastic include using a heat gun, black spray paint, or a plastic restorer. However, using a heat gun is not a long-lasting solution as the plastic may eventually fade, and after several treatments, it will no longer have enough natural oils to draw out. Similarly, torched plastic will eventually turn grey and dull, and repeated torching will damage the plastic.

Remove old polish with paint thinner

To remove old polish with paint thinner, start by identifying the type of plastic and polish on your car. Water-based polishes (like latex or acrylic) tend to have a duller sheen and fade over time, while oil-based polishes are glossier and yellow as they age.

Once you've identified the type of polish, test the paint thinner on an inconspicuous area first to ensure it won't damage the plastic. If it looks safe, proceed to apply the paint thinner to the affected area with a cotton ball or microfiber towel. Rub gently until the old polish is removed, and be sure to keep the surface wet with the thinner during this process.

It's important to note that paint thinner is strong and may damage certain types of plastic, so proceed with caution and always wear gloves and work in a well-ventilated area. If you're unsure, consider testing other solvents like olive oil, eucalyptus oil, or citrus-based gel paint removers before resorting to paint thinner.

Additionally, you can try alternative methods to restore black car plastic, such as using a heat gun, applying olive oil or a black plastic trim moisturizer, or purchasing a plastic restorer product like Solution Finish Trim Restorer. These methods can help restore the plastic's natural luster without resorting to strong solvents like paint thinner.

Use a stiff brush and wax remover

To polish black car plastic, one method is to use a stiff brush and wax remover. This process can be done by hand or with a power washer.

First, ensure you have a stiff brush suitable for the task. A small detail brush or a toothbrush can be used for this purpose. If using a power washer, a larger brush attachment can be used. Next, you will need a wax remover. There are commercial wax removers available, such as BLACKFIRE Wax Remover, or you can use an all-purpose cleaner. If you are using an all-purpose cleaner, be sure to select a product that is not solvent-based, as this may cause the colour of the plastic to fade.

Once you have your brush and wax remover, apply the wax remover to the brush and scrub the plastic. If using a power washer, apply the wax remover to the plastic first, then use the brush attachment to scrub. Be sure to follow the manufacturer's instructions for the wax remover, and exercise caution when using a power washer, as too much pressure can damage the plastic.

For particularly stubborn wax residue, there are a few alternative methods that can be used in conjunction with the stiff brush and wax remover. One option is to use a pencil eraser to remove the wax residue. Simply rub the eraser over the residue, as you would when erasing pencil marks. Another option is to use peanut butter. Apply smooth peanut butter (without bits of peanuts) to the wax residue and rub it in for a minute or two. Then, clean it off with a rag and soapy water. The oil in the peanut butter will break down the wax, making it easier to remove.

By following these steps and using a stiff brush and wax remover, you can effectively polish and restore the appearance of black car plastic.

Apply a plastic trim dye like Solution Finish

To restore black car plastic, one option is to apply a plastic trim dye like Solution Finish. Solution Finish is a well-known and highly recommended product for restoring black plastic trim. It is a silicone-free solution that uses natural oils and is VOC compliant. The product dries quickly, restoring black surfaces to a deep, rich black without a wet look.

To apply Solution Finish, follow these steps:

  • Clean the plastic trim thoroughly: Use an alcohol-based cleaner to remove any residue and ensure the surface is completely dry. Avoid using degreasers or other plastic trim cleaners as they may leave a film behind.
  • Apply Solution Finish: Using a microfiber sponge or foam applicator, apply Solution Finish Trim Restorer evenly to the plastic surface.
  • Wipe off excess product: Use a clean microfiber towel to buff off any excess oil or product.
  • Allow drying: Let the plastic trim dry for at least 6 hours. The product will dry fully and can be worked in with a machine or by hand.
  • Inspect the results: After the first application, your trim should look black and new. The results can last for 6 to 8 months or more.
  • Reapply if needed: For even longer-lasting results, consider applying a second coat after the initial application. This will help fix the damaged plastic, not just dress it.

Additionally, you can use a product called "Over The Top" as a topper over Solution Finish Trim Restorer. It is a UV protectant for plastic that lasts a long time and helps enhance and extend the life of the treatment. Allow it to dry for 20 to 30 minutes, and avoid applying more than 3 coats. Do not wash the treated area for at least 12 hours after application.
