Black plastic bumpers can lose their shine over time due to exposure to sunlight, harsh weather conditions, and general wear and tear. Restoring the shine on black plastic bumpers can significantly improve the appearance of your car, making it look newer and well-maintained. There are several methods to achieve this, ranging from household remedies such as olive oil, peanut butter, or boiled linseed oil to more advanced techniques like using a heat gun or specialised products like plastic restorers and sealants. Each method has its advantages and considerations, but with the right approach, you can effectively restore the shine on your black plastic bumpers and enhance the overall aesthetics of your vehicle.

What You'll Learn
Clean the plastic with soap and water
To shine black plastic bumpers, the first step is to clean the plastic with soap and water. This process will effectively remove any surface grime, dust, and dirt that has accumulated on the plastic surface. Here is a detailed guide on how to clean the plastic with soap and water:
Firstly, it is important to gather the necessary materials: soap, water, and a microfiber towel or cloth. A mild soap or detergent is recommended to avoid any potential damage to the plastic surface.
Next, create a mixture of soap and water. The mixture should be slightly soapy, but not overly foamy, as too much soap may leave residue on the plastic. Dip the microfiber towel or cloth into the soapy water and wring it out to remove any excess liquid.
Now, gently rub the damp cloth over the plastic surface, applying light to moderate pressure. Ensure that you cover the entire surface, including any crevices or intricate details on the bumper. The soapy water will help loosen and lift away any dirt, grime, or contaminants that may be present on the plastic.
After thoroughly cleaning the plastic, it is important to rinse the surface with clean water. This step will remove any remaining soap residue and ensure that the surface is free of any cleaning agents. Use a clean cloth or a gentle stream of water to rinse the bumper.
Finally, dry the plastic bumper thoroughly with a microfiber towel. Gently wipe the surface, absorbing any remaining moisture. Ensure that the bumper is completely dry before proceeding to the next step of the restoration process, such as applying olive oil or using a heat gun.
By following these steps, you will effectively clean the plastic bumper with soap and water, preparing it for further treatment to restore its shine and luster. Remember to take your time and be gentle during the cleaning process to avoid any scratches or damage to the plastic surface.

Use a heat gun to restore shine
Using a heat gun is an effective way to restore shine to black plastic bumpers. This method is ideal for car trims and bumpers, and can be used to renew ATVs, bikes, and motorcycles.
Before using a heat gun, ensure that you cover any nearby non-plastic objects with a tarp, as the heat can warp or discolour their surfaces. If your bumper is attached to something, cover any areas you do not want to heat with a flame-resistant tarp.
Next, clean and dry the plastic bumper. Wash the object with soap and water, removing as much debris as possible. Dry it off with a towel before applying heat to prevent burning in any dirt or stains.
When using the heat gun, ensure that you do not hover in one spot for too long, as this can cause slight distortion. Keep the heat gun around three inches away from the bumper and use a high heat setting. The heat will open up the plastic's cells, allowing moisture to escape and restoring its colour.
After using the heat gun, you can further enhance the shine by adding olive oil to the plastic's surface. You can also use a can of black shoe polish to achieve a deep black shine, before sealing it with wax.

Apply olive oil or boiled linseed oil
Applying Olive Oil or Boiled Linseed Oil to Shine Black Plastic Bumpers
Black plastic bumpers are prone to fading and discolouration over time. One way to restore the shine to black plastic bumpers is by applying olive oil or boiled linseed oil.
Cleaning the Bumper
First, clean the bumper to ensure the oil can be properly absorbed. Wash the bumper with soap and warm water, removing any dirt or stains. Dry the bumper thoroughly with a towel.
Applying the Oil
Pour a small amount of oil onto a washcloth or paper towel. A coin-sized amount of oil is usually sufficient, and you can always add more later if needed. Rub the oil into the plastic in a circular motion for a few minutes.
Buffing the Bumper
After applying the oil, use a dry cloth to buff the bumper. Wipe the bumper in circular motions, applying heavy pressure to remove any excess oil and give the plastic an extra shine.
Inspecting for Residual Discolouration
Once the oil has been removed, inspect the bumper for any remaining discolouration. If there are any patches that the oil did not restore, repeat the process, targeting the stubborn areas directly. For severe fading or discolouration, you may need to consider alternative methods, such as using a heat gun or spraying the bumper with black paint.
Maintenance
Olive oil and boiled linseed oil can effectively restore the shine to black plastic bumpers. However, it may need to be reapplied periodically, especially if the bumper is exposed to sunlight frequently. To maintain the shine, regularly clean the bumper with soap and water, and reapply the oil as needed.

Use a black plastic trim moisturiser
Black plastic trim moisturiser is a great way to restore the shine to black plastic bumpers. It is a simple, cost-effective way to improve the appearance of your car. The use of a moisturiser is preferable to the use of a heat gun, which can warp or discolour surfaces, and is a short-term solution that can damage the plastic.
To use a black plastic trim moisturiser, first, ensure the plastic is clean and dry. Wash the plastic with soap and warm water, and dry it off with a towel. Next, apply a small amount of the moisturiser to an applicator pad or a microfiber sponge. Spread a thin coat of the moisturiser over the area in an even motion, covering the area completely. Allow the solution to penetrate for 3-4 minutes. Finally, use a clean microfiber towel to buff off any excess, and wipe off any glass or paint.
It is recommended that you wear gloves and eye protection when applying the moisturiser, as it can stain clothing and skin. It is also important to ensure the area is well-ventilated.
After the first application, your trim will stay black and look new for approximately 8 months or more. A second application can last even longer, as the moisturiser works to fix the damaged plastic, not just dress it. To UV-protect the surface, you can use a plastic sealer. This can be used as a standalone treatment on new or good-condition plastics, or as a topper on plastics that have been restored with a moisturiser.

Spray paint the plastic black
If your black plastic bumpers are looking faded and discoloured, you can spray paint them to give them a sleek, shiny new finish. Before you start, ensure you are in a well-ventilated area and cover any surrounding areas that you don't want to get paint on. You can use a tarp or a large piece of cardboard to protect the surrounding area.
First, clean the bumpers with soap and warm water to remove any dirt, grease, or road grime. Dry the bumpers thoroughly with a clean towel. It is important to ensure that the bumpers are completely dry before moving on to the next step.
Next, you will need to sand the bumpers lightly to create a rough surface that the paint can adhere to. You can use fine-grit sandpaper or a Scotch-Brite pad for this step. Sand the entire surface of the bumper evenly, being careful not to create any deep scratches.
Once you have finished sanding, wipe down the bumpers with a tack cloth or a damp cloth to remove any dust or debris. It is important to ensure that the surface is completely clean and dry before painting.
Now, you are ready to prime the surface. Apply a thin, even coat of plastic primer to the bumpers, following the directions on the product for drying time. The primer will help the paint adhere better and create a more durable finish.
Finally, you can start painting! Shake the can of spray paint well and hold it about 8-12 inches away from the surface of the bumpers. Spray in steady, even strokes, overlapping each stroke slightly to ensure full coverage. Apply several thin coats, allowing adequate drying time between coats, rather than one heavy coat.
After the final coat, let the paint dry completely. You may want to apply a clear coat or sealant to protect the paint and add an extra shine.
