What You'll Learn
Using brake fluid
Brake fluid can be used to remove paint from motorcycle plastic. It reportedly does a good job of removing paint without damaging the plastic body parts. Here is a step-by-step guide on how to use brake fluid to remove paint:
Prepare the Work Area
Before you begin, ensure you are working in a well-ventilated area as the chemical action of the brake fluid may smell. Put on solvent-resistant gloves to protect your hands from the fluid. If you have sensitive skin, consider wearing long sleeves and pants to avoid any potential irritation.
Apply the Brake Fluid
Create a form-fitting "bowl" with aluminium foil to minimise the amount of fluid needed and to ensure full coverage of the painted area. Pour the brake fluid into the foil bowl, ensuring that it completely covers the painted surface. You can also spray the brake fluid directly onto the painted area, making sure to apply it heavily.
Let it Soak
Allow the brake fluid to soak for several hours or even overnight. The longer you let it soak, the more effective it will be at breaking down the paint.
Remove the Paint
After soaking, you should see that most of the paint has softened and is ready to be removed. Use a soft-bristled brush to scrub away any remaining stubborn spots. If the paint is still not coming off easily, you can use a non-abrasive plastic tool or a plastic scraper to gently lift it off.
Clean the Surface
Once all the paint has been removed, it is important to thoroughly clean the plastic to remove any residue. Use hot water and soap to scrub the surface, ensuring that you remove any remaining brake fluid. Rinse the part with clean water and, if possible, run it through a dishwasher cycle to ensure that all traces of the fluid are gone.
Post-Treatment Care
After the part has been cleaned and dried, inspect it for any signs of damage. If the plastic appears to be unaffected, you can proceed with repainting or applying a protective coating. However, if there are any signs of discolouration or warping, you may need to seek professional advice or consider replacing the plastic part.
It is important to note that while brake fluid is effective at removing paint, it may not work for all types of paint. Additionally, always exercise caution when working with chemicals, and follow the manufacturer's instructions and safety guidelines.

Sanding
To begin the sanding process, it is recommended to start with a lower grit sandpaper, such as 220-grit, to remove the majority of the paint. This should be done carefully and slowly to avoid damaging the plastic. Once the majority of the paint has been removed, a finer grit sandpaper, such as 400-grit, can be used to even out the surface and remove any remaining paint. It is important to avoid using a very coarse grit, such as 80-120 grit, as this can dig too deep into the plastic and cause damage. After sanding, it is essential to clean the plastic surface thoroughly to remove any dust or residue. This can be done using a tack cloth or a soft brush.
Wet sanding is another technique that can be used to remove paint from motorcycle plastic. This involves soaking the surface in water or using a lubricant, such as mineral spirits, to reduce friction and heat build-up during the sanding process. Wet sanding can be more effective in removing paint without damaging the plastic but requires more time and effort. It is important to use a finer grit sandpaper, such as 600-grit, for wet sanding to avoid scratching the plastic.
After sanding, it is crucial to prepare the plastic surface for repainting. This includes cleaning the surface with soap and water to remove any remaining dust or residue and ensuring that the plastic is completely dry before applying primer or paint. It may be necessary to use a degreaser to ensure the surface is free of any contaminants. Once the surface is clean and dry, a primer can be applied, followed by the desired paint colour.
While sanding is a viable option for removing paint from motorcycle plastic, it is important to note that it can be a time-consuming and labour-intensive process. It may not be suitable for those seeking a quick solution, as it can take weeks to achieve a smooth and even surface. Additionally, there is a risk of damaging the plastic if the incorrect grit sandpaper is used or if the sanding is not done carefully. Therefore, it is essential to exercise caution and patience when using this method.

Paint stripper
To use a chemical paint stripper, first, apply the stripper to the painted surface of the motorcycle. Then, wait for the paint to soften—this should take a few minutes. Finally, use a putty knife or another sharp tool to scrape off the softened paint. It is important to follow the instructions on the stripper carefully, as some can be quite caustic. You may need to apply several coats of stripper to completely remove the paint.
After using a chemical paint stripper, it is important to clean the plastic surface to get rid of any stripper residue. Use soap and water for this. It is also recommended to use a power washer or a dishwasher cycle to ensure all the residue is removed.
An alternative to using a chemical paint stripper is to use brake fluid. However, this method may damage the plastic. It is important to use a soft-bristled brush and solvent-resistant gloves when using this method, and to work in a well-ventilated area. After using brake fluid, scrub the motorcycle with hot water and soap to remove any residue.
