The best method to clean oil paint off plastic depends on the type of plastic and the thickness of the paint. For example, if you are dealing with a thin layer of fresh paint, it should easily scratch or scrape off.

What You'll Learn
Use warm soapy water
Warm soapy water is a good starting point for removing paint from plastic. It is the best method for water-based paints, which are now the most common type of household paint.
Begin by soaking a dishcloth in warm water and soap. Then, rub at the paint until it starts to come away. If the paint is a thin and freshly dried layer, it should easily scratch or scrape off. You can use a flat-edged scraper to gently remove the paint.
If the paint is more stubborn, you can try using cooking oil, such as olive or vegetable oil, to soften it. Apply the oil to the paint with a cloth and leave it to sit for a few minutes. Then, keep rubbing and wiping at the paint until it is gone.
It is important to identify the type of plastic and paint you are dealing with before attempting to remove the paint, as some solvents can damage certain types of plastic. For example, if you are trying to remove oil-based paint, you may need to use a chemical paint stripper or mineral spirits. Always test any solvent in an inconspicuous area first to ensure it won't damage the plastic.

Try vegetable oil
Removing oil paint from plastic can be challenging, and it is important to act quickly before the paint dries. While some sources suggest using nail polish remover or fine-grit sandpaper, vegetable oil can also be an effective and safe solution for removing oil paint from plastic surfaces.
Vegetable oil can be used to remove oil paint from plastic, but it is important to note that it is only effective if the paint is still wet. Any common vegetable oil, such as safflower, sunflower, corn, or rapeseed, or even olive oil, can be used. Simply apply the vegetable oil to the paint and then gently remove it with paper towels or a rag. This method may require some elbow grease, but it is a safe and inexpensive option for removing oil paint from plastic.
It is worth mentioning that vegetable oil is not as effective as petroleum-based solvents for removing paint. Additionally, it is crucial to avoid using vegetable oil directly on the canvas, as it will not dry and can contaminate your paint. If you plan to use vegetable oil for cleaning brushes, ensure that you wash the brushes with dish detergent afterward to prevent paint contamination.
For dried paint on plastic, other methods may be more effective, such as using a paint scraper or a razor blade. However, these methods may not be suitable for all types of plastic, as they can cause scratches or damage. In such cases, vegetable oil can be used to soften the dried paint before attempting to remove it, increasing your chances of success.
To avoid the hassle of removing dried paint, it is recommended to wipe off any excess paint from your palette or plastic surface immediately and let it dry before scraping it off. This will make the cleaning process much easier and help prevent paint buildup.

Use a paint stripper
Paint strippers are effective for removing oil-based paint from plastic. However, it is important to note that not all paint strippers are created equal, and some can be too harsh for plastic surfaces, causing damage or even melting. Therefore, it is crucial to choose the right type of paint stripper and follow the necessary safety precautions.
Firstly, identify the type of plastic you are working with. Different plastics have distinct properties, and some may be more susceptible to damage from certain solvents. Common types of plastic include ABS, a rigid material used in automotive parts; acrylic or plexiglass, which is strong and transparent; polyethylene, which can be thin like plastic bags or milky white like cartons; and nylon, a soft and malleable material found in guitar strings and clothing. Knowing the type of plastic will help you select the safest solvent.
Once you have identified the plastic type, it is essential to choose a suitable paint stripper. Avoid harsh chemicals and opt for something safer, like a citrus-based stripper. While these may be slower and weaker, they are less likely to damage the plastic. Always read the label and follow the manufacturer's instructions for proper usage. Before applying the stripper to the entire surface, test it on a small, inconspicuous area to ensure it does not harm the plastic.
When using a paint stripper, work in a well-ventilated area to avoid inhaling fumes. Wear protective gear, such as rubber gloves and an apron, to shield your skin from the chemicals. Apply the stripper generously to the painted area and let it sit for the recommended amount of time. Then, use a plastic scraper or a tool that won't scratch the surface to gently remove the paint. If needed, reapply the stripper and repeat the process until the paint is completely removed.
After removing the paint, thoroughly clean the plastic surface with soapy water or a high-quality cleanser to get rid of any remaining stripper residue. Ensure you dry the surface completely once you're done. Remember, always exercise caution when working with paint strippers, and if you're unsure about a particular product, it's best to test it on a small area first.

Try nail polish remover
If you're looking to remove oil paint from plastic, you may want to try nail polish remover. This is because nail polish remover is acetone, which is an effective paint remover. It is also safe and popular for removing oil-based spray paint from plastics without scratching the surface.
However, it is important to note that nail polish remover can sometimes melt plastic, so it should be used sparingly and carefully. To use nail polish remover to remove oil paint from plastic, start by applying a small amount to a rag and testing it on a small area of the plastic. If the plastic is not damaged, continue by pouring enough nail polish remover to cover the affected area and rub and wipe with a clean rag or paper towel. Repeat this process as necessary until the paint is gone. It is also important to work in a well-ventilated area, as most nail polish removers carry a strong odour.
If you are concerned about damaging the plastic, you may want to try other methods, such as using vegetable oil, which is safer but less effective, or denatured alcohol, which is stronger than nail polish remover but safer than other solvents.

Use paint thinner
If you are looking to clean oil paint off a plastic surface, it is important to be cautious as the wrong solvent can damage the plastic. While paint thinner is a recommended option for removing oil paint from plastic, it is important to note that it may not be effective on dried paint spots.
If you choose to use paint thinner, start by pouring enough of the solvent onto a cotton ball to cover the affected area. Then, rub the paint with the cotton ball until the paint is removed. You can also place small items in a container with the paint thinner for 1-3 hours. After soaking, scrape the paint off with a plastic scraper or your fingernail, being careful not to apply too much pressure to avoid scratching or damaging the plastic.
It is recommended to test the paint thinner on an inconspicuous area of the plastic first to ensure it will not cause damage. Additionally, it is important to be cautious when using paint thinner and similar solvents, as they can be toxic and require careful handling. Always read the instructions and take the necessary precautions when using these products.
If the paint thinner is ineffective, you may need to try other methods or stronger solvents. Some alternatives to paint thinner include mineral spirits, acetone, and nail polish remover. However, these stronger solvents may damage the plastic, so it is important to proceed with caution and always test on a small area first.
