What You'll Learn
Use paint thinner, acetone, or paint remover
When using paint thinner, acetone, or paint remover, it is important to take safety precautions due to the toxicity of these substances. Wear protective gear, such as closed-toe shoes, long pants, a long-sleeve shirt, gloves, safety goggles, and a mask or respirator. Ensure the area is well-ventilated by opening doors and windows, and consider setting up fans to disperse harmful fumes. Cover surfaces you want to protect, such as the floor, furniture, or plants, with a plastic drop cloth.
Before applying any of these substances, it is recommended to test them on a small, inconspicuous area of the plastic to ensure they will not cause damage or discolouration. If the plastic changes colour or texture, or indents when pressed, try a different solvent.
Acetone is a powerful solvent that can be used to remove paint from plastic, but it may damage or melt certain types of plastic. To use acetone, soak a rag or cotton ball with the solvent and apply it to the painted area. Keep the area wet for a few minutes, then use a tool, such as a plastic scraper or putty knife, to remove the loosened paint. You can also use a stiff brush to scrub away the paint.
Paint thinner and paint remover are effective for removing oil-based paints from plastic. Apply the paint thinner or remover to the painted area and let it soak in. Then, use a tool, such as a scraper or putty knife, to remove the paint. For textured surfaces, paint remover or paint thinner can reach into nooks and crannies, making it easier to clean off the spray paint.
Denatured alcohol is another solvent that can be used to remove latex or water-based paints from plastic. Apply a liberal amount of denatured alcohol to the painted area and wait for the paint to dissolve and wrinkle. Then, use a plastic scraper or putty knife to scrape off the paint. You can also use a rag or sponge to scrub the area and remove the paint.

Try a pressure washer on a low setting
Pressure washers can be used to remove spray paint from plastic. However, it's important to exercise caution when using this method, as the high pressure and incorrect angle of the spray can damage the painted surface. Therefore, it is recommended to use a pressure washer on a low setting to avoid such damage.
Before using a pressure washer, clear the surrounding area to avoid accidents. Wear protective gear, including closed-toe shoes, long pants, a long-sleeve shirt, gloves, safety goggles, and a mask or respirator. Ventilate the area by opening doors and windows and setting up fans to disperse harmful chemical fumes. Put down a drop cloth to cover surfaces you want to protect, such as the floor, furniture, or plants.
When using the pressure washer, start by spraying the painted area with water. Then, carefully adjust the pressure washer to a low-pressure setting and slowly move the nozzle back and forth along the painted plastic surface until all the paint has been removed. Finish by thoroughly rinsing and cleaning up any remaining dirt and spray paint residue.
If the paint is particularly stubborn, you may need to use a paint remover or paint thinner in conjunction with the pressure washer. Apply the paint remover according to the manufacturer's instructions, allowing it to soak into the paint before using the pressure washer to scrub and rinse the area.
By following these steps and maintaining a low-pressure setting on your pressure washer, you can effectively remove spray paint from plastic surfaces without causing damage.

Apply vinegar and scrub with a brush
Removing spray paint from plastic can be tricky, and the type of paint and plastic you're dealing with will determine the best method for removal. Before attempting to remove spray paint from plastic, it is important to note that some heavy-duty paint removers may discolour, scar, or even melt some plastic surfaces. Therefore, it is recommended to use light cleaning solutions and physical methods for removing spray paint from plastic.
One such light cleaning solution is vinegar. To apply this method, follow these steps:
Step 1: Identify the Type of Paint
Before attempting to remove the spray paint, it is important to identify whether the paint is oil-based or water-based. Removing water-based spray paint is relatively easy, and it usually comes off with soap and warm water scrubbing. Removing oil-based spray paint is more difficult and usually requires a solvent such as vinegar.
Step 2: Prepare the Vinegar
For this method, you will need to use distilled white vinegar. It is important to use distilled vinegar as it is stronger and more effective at removing paint. Regular white vinegar can be diluted and may not be as effective. Apply the vinegar to a rag or cloth. Ensure the rag is soaked but not dripping.
Step 3: Apply Vinegar to the Painted Area
Using the soaked rag, apply the vinegar to the painted area. Make sure that the vinegar covers all the painted sections. You may need to re-soak the rag and apply vinegar multiple times to ensure the area is thoroughly covered.
Step 4: Allow the Vinegar to Soak
Let the vinegar sit on the painted area for a few minutes. This will give the vinegar time to penetrate the paint and start to loosen its bond with the plastic. You may notice the paint starting to lift or bubble, which is a sign that the vinegar is working.
Step 5: Scrub with a Brush
After allowing the vinegar to soak, use a brush to gently scrub the painted area. A stiff-bristled brush or an old toothbrush can be effective for this step. Work in small sections and scrub in a circular motion, applying light pressure at first to avoid damaging the plastic. Rinse the brush frequently in warm water to remove any paint residue and prevent it from redepositing on the plastic.
Step 6: Repeat as Needed
If there is still paint remaining on the plastic, repeat steps 3 to 5 until all the paint has been removed. It may take multiple applications to completely remove the spray paint, depending on the thickness of the paint and the type of plastic.
Step 7: Clean the Area
Once all the paint has been removed, use warm water and a mild soap to clean the area. This will help to remove any remaining paint residue and vinegar odour. Dry the area thoroughly with a soft cloth or towel.
It is important to note that vinegar may not be effective for removing paint from all types of plastic, and it may require multiple applications or a stronger solvent. Always test the vinegar on a small, inconspicuous area first to ensure it does not damage or discolour the plastic. Additionally, wear protective gear, such as gloves and eye protection, when working with vinegar to avoid skin and eye irritation.

Remove the Paint:
After the soak time, use a soft cloth or cotton ball to gently wipe away the paint. You may need to apply light pressure and rub in a circular motion to lift the paint from the plastic surface. If necessary, use a stiff brush to gently scrub away any remaining paint residue.
Repeat as Needed:
If there are still traces of paint on the plastic surface, repeat the process until all the paint is removed. Be patient and gentle during this process to avoid damaging the plastic.
Clean and Dry the Surface:
Once all the paint has been removed, use a damp cloth or sponge to wipe down the plastic surface, removing any residual nail polish remover. Then, dry the surface thoroughly with a soft, clean cloth.
It is important to note that nail polish remover may not be effective for all types of paint, especially oil-based paints. If the paint is particularly stubborn, you may need to try alternative methods or seek professional advice.

Use a paint scraper or razor blade
Paint scrapers or razor blades can be used to physically remove spray paint from plastic. However, it is important to work carefully to avoid damaging the underlying material. Before using a paint scraper or razor blade, you can try using other methods to remove the spray paint. For example, you can apply a paint stripper or solvent according to the manufacturer's instructions and allow the product to penetrate the paint. Then, scrub the surface using a brush or abrasive pad. You can also try using a power washer on plastic surfaces. However, using a pressure washer comes with risks, so be cautious about the water pressure and the angle of the spray to avoid damaging the painted surface.
If these methods are unsuccessful, you can try using a paint scraper or razor blade. First, gently slide the scraper or razor blade along the surface of the plastic at a 45-degree angle to scrape off the layers of spray paint. You can also try wrapping the scraper in a cloth to prevent it from scratching the surface beneath the spray paint. Be careful not to cut yourself or damage the underlying material. If you are working with paint thinner, acetone, paint remover, or other toxic substances, take proper precautions to stay safe. Wear protective gear, including closed-toe shoes, long pants, a long-sleeve shirt, gloves, safety goggles, and a mask or respirator. Ventilate the area before you begin by opening doors and windows and setting up one or more fans to disperse harmful chemical fumes.
