ABS plastic is notoriously difficult to polish, but there are a few methods that can be used to restore shine and remove scratches. It's important to note that some methods may work better for harder ABS plastic than softer plastic. One popular method is to use a polishing compound, which can be applied by hand with a soft cloth or with a machine such as a drill or rotary tool. Other methods include using a blow torch or heat gun, sandblasting, or dipping a soft mop brush in acetone and teasing the surface. It's also important to consider the type of polish being used, as some polishes are designed specifically for plastic car dashboards, while others are meant for different types of plastic.

Avoid harsh chemicals
ABS plastic is widely used due to its excellent balance of mechanical properties, chemical resistance, and affordability. However, to maintain its appearance and function, it requires proper maintenance, including occasional cleaning and polishing.
When it comes to polishing ABS plastic, it is crucial to avoid harsh chemicals that can cause damage. While some sources suggest using acetone, it is important to note that it may attack the surface and cause hazy discolouration. Similarly, while carnauba wax is often used on car dashboards, it may create a greasy appearance and attract dust.
Instead of harsh chemicals, opt for mild cleaning agents such as mild soap and water or a mild interior cleaner specifically designed for automotive surfaces. For tough grease or grime buildup, isopropyl alcohol can effectively clean ABS without causing damage. Always refer to manufacturer guidelines when using solvents or cleaners to avoid cracking or hazing.
To remove scratches from ABS plastic, you can use mild abrasives such as toothpaste, baking soda, or sandpaper. When using sandpaper, start with a finer grit, such as 320-grit, to smooth out deep scratches before progressing to finer grades. It is important to work in small areas and always move in a circular motion to buff out scratches effectively.

Prevent scratches by using lint-free cloths
When polishing your plastic dashboard, it is important to use a soft and lint-free cloth to prevent scratches. Microfibre cloths are a good option as they are soft and won't leave lint on the surface.

Opt for a high-quality dashboard polish that is specifically designed for plastic car dashboards. You can also use a mild interior cleaner or a product designed for automotive surfaces.
To prevent scratches, it is important to regularly clean your dashboard. Dust and dirt particles can cause scratches if they are not removed regularly. You can also use a dashboard protector to prevent UV damage and maintain the shine of your dashboard.
In addition to using lint-free cloths, there are other ways to prevent scratches on your plastic dashboard. Avoid using harsh chemicals or abrasive materials that can damage the surface. If you are using a buffer or sandpaper, be sure to use a gentle touch and always move in the direction of the scratch, not against it.

Wash with a mild cleanser
To polish an ABS plastic dash, it is important to wash it with a mild cleanser to remove dirt, dust, and debris. This step is crucial as it prepares the surface for the polishing process, ensuring that the polish adheres evenly and effectively. Here are some detailed instructions for washing your plastic dash with a mild cleanser:
Choose the Right Cleanser
Opt for a mild interior cleanser designed for automotive surfaces or plastic surfaces. Avoid using household cleaners as they may contain harsh chemicals that can damage the plastic. Look for products specifically formulated for car dashboards or automotive plastics.
Prepare the Surface
Before applying the cleanser, ensure the surface is free of any loose dirt or debris. Use a soft, lint-free microfiber cloth to gently wipe down the dashboard and remove any dust or soil particles. This step ensures that you are working with a clean surface, free of any contaminants that could interfere with the cleansing process.
Apply the Cleanser
Follow the instructions on the chosen cleanser and apply a small amount to a clean, soft cloth or microfiber cloth. Gently work the cleanser into the dashboard, covering the entire surface. Pay extra attention to areas with built-up dirt or stains. Be cautious not to apply excessive pressure, as it may cause scratches on the plastic.
Rinse and Dry
After cleansing, use a damp cloth to wipe away any residual cleanser from the dashboard. Ensure that all cleanser residue is removed to avoid streaking or clouding. Once rinsed, dry the surface thoroughly with a soft, absorbent cloth. It is important to ensure that the dashboard is completely dry before proceeding to the next step, which is polishing.
Test on a Small Area
Before proceeding to polish the entire dashboard, it is advisable to test on a small area first. This helps ensure that the cleanser is compatible with the plastic and does not cause any discolouration or adverse effects. Choose a small section of the dashboard and follow the cleansing and drying process. Observe the results before proceeding to clean the entire dash.
By following these steps, you can effectively wash your ABS plastic dash with a mild cleanser, preparing it for the subsequent polishing process. Remember to choose the right cleanser, prepare the surface, apply the cleanser gently, and always test on a small area first to ensure satisfactory results.

Use a blow torch for a smooth finish
Using a blow torch can be an effective way to restore the shine to your ABS plastic dash and achieve a smooth finish. This method is particularly useful for treating faded plastics and can produce long-lasting results.
Before using the blow torch, ensure that your dashboard is clean and free of any dirt, dust, or debris. Use a mild cleanser or interior cleaner and a microfiber cloth to gently wipe down the surface. Avoid using harsh chemicals or abrasive products, as these can damage the plastic.
When using the blow torch, wear flame-resistant gloves for protection. Hold the blow torch in one hand and the plastic dash in the other, or set the dash on a heat-resistant surface. Slowly move the blow torch along the surface of the dash, taking care not to hold it too close or apply direct heat for an extended period, as this can cause discoloration or damage to the plastic.
The heat from the blow torch will help to open the pores of the plastic and restore its shine. For an even smoother finish, consider applying a small amount of mineral oil to the dash after heating it with the blow torch. Wipe away any excess oil and let the dash bake in the sun for a few hours. Finally, wipe down the dash again to remove any remaining residue.
Using a blow torch on your ABS plastic dash can be an effective solution for restoring shine and smoothness. However, it is important to exercise caution and avoid overheating the plastic to prevent any potential damage. Always test on a small, inconspicuous area first to ensure satisfactory results.
