Cleaning products
To restore your plastic car running boards, it is important to first clean them thoroughly. This will ensure that any dirt, grime, or other debris is removed, allowing the restoration products to adhere properly.
There are a variety of cleaning products available that can be used to clean plastic car running boards. A gentle soap and water solution can be used to clean the boards, removing any dirt or grime. A soft-bristled brush can be used to scrub away any stubborn stains or dirt buildup. An all-purpose cleaner can also be used, applied to a soft, clean, damp cloth or microfiber towel to rub off dust and dirt, paying special attention to the grooves. It is important to avoid using harsher cleaning products as they may contain chemicals that can damage the boards.
After cleaning with soap and water or an all-purpose cleaner, a plastic cleaner can be used to remove any remaining stubborn stains or marks. Popular plastic cleaners include Meguiar's, Power Clean, and Pinnacle Leather & Vinyl Cleaner Solution Finish Black Plastic & Vinyl Restorer.
Once the boards are clean, they can be prepared for further restoration. This may include sanding with fine-grit sandpaper to create a smooth surface, or using a plastic adhesion promoter and primer to prepare the surface for painting.
Additionally, there are various dressing products available that can be used after cleaning to restore the natural colour of the running boards, repel dust and lint, and protect them from UV radiation, fading, and cracking. These products should leave a matt-dry finish and not feel oily or greasy. Popular options include Mother’s Back to Black, 303 Automotive Protectant, Meguairs Natural Shine Protectant, Solution Finish Black Plastic, and Chemical Guys Back to Black.

Scrubbing tools
To begin the cleaning process, you will need a high-quality plastic cleaner. This product is designed to remove dirt and grime buildup from plastic surfaces. It is important to use a cleaner that is specifically formulated for plastic to ensure that you do not cause further damage to the surface. Apply the plastic cleaner to a soft, clean cloth or microfiber towel and gently rub it onto the plastic surface to remove dust and dirt. You can also use a soft-bristled brush to help scrub away any stubborn stains or dirt buildup. Make sure not to scrub too hard, as you could scratch the plastic.
If your plastic running boards are heavily soiled or caked with mud, you may need to use a scrubbing brush with stiffer bristles. A fender brush or a heavy-duty DA carpet brush can be effective in removing stubborn dirt and grime. You can also use a combination of scrubbing by hand and with a brush attachment on a rotary polisher at very low RPMs. For intricate details or harder-to-reach areas, a small, handheld brush, such as the Tornador Black Air Blow Out Gun, can be useful.
Once you have thoroughly scrubbed and cleaned the plastic surface, you may need to use a pressure hose or a cloth/sponge with water to rinse away any remaining soap and dirt. It is important to ensure that all cleaning products are removed from the surface before moving on to the next step of restoration.
In addition to scrubbing tools, you may also need sandpaper to smooth out any rough surfaces before applying a primer and paint to restore the appearance of your plastic running boards.

Plastic restoration
Plastic car running boards are a common component of modern vehicles, usually running along the sides of the car and serving as a step to assist passengers in getting in and out of the car with ease. They are made of plastic to ensure durability and resistance to wear and tear over time. However, due to constant exposure to harsh weather conditions and other environmental factors, they can become discoloured, faded, cracked, or stained, detracting from the overall appearance of the car.
Fortunately, restoring plastic car running boards is a straightforward process that can be accomplished with the right tools and a bit of elbow grease. Here is a step-by-step guide on how to restore plastic car running boards:
Materials and Tools:
- High-quality plastic cleaner
- Plastic restorer
- Soft-bristled brush
- Heat gun
- Sandpaper
- Plastic primer
- Spray paint
- Clear coat
Steps:
- Cleaning and Scrubbing: Start by applying a small amount of an all-purpose cleaner onto a soft, clean piece of damp cloth or microfiber towel. Use it to rub off the dust, dirt, and grime buildup from the plastic surface. For stubborn stains or dirt, use a soft-bristled brush to scrub them away.
- Using a Heat Gun: A heat gun is essential in softening the plastic surface, making it easier to remove any remaining dirt and grime. It also helps to melt away oxidation, restoring the original colour of the plastic.
- Smoothing with Sandpaper: Use sandpaper to smooth out any rough surfaces left after cleaning and heat treatment. This step is crucial for achieving a smooth finish and ensuring the plastic surface is ready for primer and paint application.
- Applying Primer: Apply a plastic primer to the sanded surface. The primer ensures that the paint adheres properly to the plastic and prevents it from chipping or peeling off later.
- Painting: Choose a spray paint that matches the colour of your car's running boards. The paint will not only restore the colour but also provide a protective layer against UV rays and other environmental factors.
- Applying a Clear Coat: Finish the process by applying a clear coat over the painted surface. This will seal in the paint, giving it a glossy finish and protecting it from scratches and fading.
Additional Tips:
- There are various plastic dressing products available that can restore the natural colour, repel dust and lint, and protect against UV radiation, fading, and cracking. Choose a product that leaves a matt-dry finish and is not greasy or slippery.
- For extremely faded or discoloured running boards, consider using products like Forever Black, Solution Finish, Plasti Dip, Krylon Fusion, or Krylon Dual Bond Satin Black.
- Regular cleaning and maintenance of your plastic running boards will help maintain their appearance and prolong their lifespan.

Heat gun method
Restoring plastic car running boards using a heat gun is an effective method, but it requires careful application and a good understanding of the process and the material being worked on. Firstly, it is essential to clean the plastic surface with a gentle soap and water solution and a plastic cleaner to remove any stubborn stains or marks. The heat gun must be held four to six inches away from the surface for optimum results. The key is to use consistent, moderate heat and not overheat the trim, as excessive heat can cause the plastic to warp, melt, or become brittle. The heat gun works by increasing the heat and drawing out the oils underneath the trim, breaking down the molecular composition of the faded plastic, bringing the pigment back to the surface. This process often results in a rich, glossy appearance that makes the plastic look nearly new. However, achieving this outcome requires patience and precision, as rushing through it can result in uneven results or permanent damage to the plastic. While a heat gun can be an excellent option for restoring plastic, it is important to note that it can also damage the surface if not used correctly.

Painting
Cleaning and Preparation:
Firstly, ensure you have the necessary cleaning supplies, including automotive degreaser, soap, water, and microfiber cloths. Use the degreaser to remove any stubborn grime, followed by a wash with automotive soap and water to thoroughly clean the running boards. If there is any loose paint, use a soft-bristled brush or a wire brush to scrub it away.
Sanding:
Once the surface is clean, it's time to sand it. Collect sandpaper in various grits (80, 220, and 400), a sanding block, and other protective items like plastic sheeting and painter's tape. Start with a coarser grit (around 80-grit) to remove any existing finish and surface imperfections. Then, use a finer grit (220 or 400) to smooth out the surface and create the perfect base for paint adhesion. Ensure all scratches, dents, and imperfections are addressed during this step.
Priming:
Before painting, it is essential to use a plastic primer to ensure the paint adheres properly and to achieve a smooth and even finish. Apply a plastic adhesion promoter to promote the paint's bonding. You can use a heat gun at this stage to soften the plastic surface and make it easier to work with, but exercise caution to avoid damaging the plastic or surrounding areas.
Now, you are ready to paint. Choose a high-quality automotive-grade plastic paint in your desired colour. You can use paintbrushes, rollers, or an automotive spray gun for application, depending on your preference. Ensure you are working in a well-ventilated area and wearing proper safety equipment, such as gloves, safety glasses, and a respirator mask.
Clear Coat:
After painting, apply a clear coat to seal in the paint and provide extra protection and shine. This step will also give your running boards a glossy finish and help protect them from scratches and fading.
Remember that patience is essential throughout the process, especially during preparation and between coats. Allow sufficient time for the paint to cure completely, which can take 7-30 days depending on the paint type and environmental conditions.
