Removing paint from plastic can be a tricky business, especially if you're dealing with dried paint. The first step is to identify the type of paint and plastic you're working with, as this will determine the best method for removal. Once you know the type of paint, you can choose the right solvent or removal method. It's important to test any solvent in an inconspicuous area first to ensure it won't damage the plastic. There are various methods to remove paint, from using paint strippers and removers to natural solutions like baking soda and vinegar. For large areas, you can use a cotton ball or stiff-bristled brush, and for small, intricate details, a toothbrush can be useful.

What You'll Learn
Use a paint scraper
Paint scrapers are great for removing paint from flat plastic surfaces. They are particularly effective on plastics with a smooth finish, as the scraper blade can sit flush against the surface. When using a paint scraper, it is important to be gentle and apply constant, steady pressure. Start at any corner or edge of the paint spill and gently slide the scraper underneath, lifting off the paint. Be careful not to apply too much pressure, as this can damage the plastic. For contoured or curved plastic surfaces, a razor blade or your fingernail may be a better option. Hold the scraping tool at a slight angle and gently push it under the painted surface.
Before using a paint scraper, you can apply certain substances to the paint to soften it and make it easier to remove. One option is to soak the area in soapy water or vegetable oil for at least 20 minutes, then try scraping again. Alternatively, you can use a mixture of baking soda and vinegar. Apply this mixture to the paint and let it sit for about 30 minutes before scraping. For dried paint, rubbing alcohol can be effective in loosening it. Apply the rubbing alcohol to the paint and cover it with plastic wrap. Leave it for about 30 minutes, then remove the plastic wrap and try scraping off the paint.
If the paint is still stubborn and difficult to remove, you may need to use a paint stripper or solvent. However, be cautious when choosing a solvent, as some types of plastic may react poorly to certain solvents. Always test the solvent on an inconspicuous area of the plastic first to ensure it won't cause damage. Some solvents may need hours before they have an adverse effect, so be patient and observe any changes in the plastic's colour, texture, or indentation. If the solvent seems safe, apply it to the painted area and use a paint scraper to remove the loosened paint.
It is important to prioritize safety when using paint scrapers and solvents. Wear gloves to protect your skin and a respirator mask to guard against inhaling fumes. Make sure the area is well-ventilated to avoid breathing in harmful chemicals. Always read the instructions and warnings on any products you use, and dispose of them properly.

Try a paint thinner
Paint thinner is a viable option for removing paint from clear plastic. However, it is important to test it on a small area first to ensure it does not damage the plastic. Start by identifying the type of plastic and paint to determine the safest solvent to use. Water-based paints like latex or acrylic tend to have a duller sheen and fade over time, while oil-based paints are glossier and yellow as they age. If you are unsure, you can test the paint type by taking some dry paint and trying different solvents.
Once you have identified the paint type, proceed to test the paint thinner on a small, inconspicuous area of the plastic. If it does not cause any damage, you can move forward with the paint removal process. Apply a liberal amount of paint thinner to the painted area and wait for a few minutes to allow the paint to dissolve. Keep the area wet during this process. As the paint starts to wrinkle, use a plastic scraper or your fingernail to gently scrape it off. For flat surfaces, a plastic paint scraper is ideal as it has a straight edge that won't scratch the surface. For curved surfaces, your fingernail may work better.
If the paint is particularly stubborn, you can try using a stronger solvent like denatured alcohol or acetone. However, be cautious as these solvents can be more harmful to the plastic. Always wear gloves and a respirator mask to protect your skin and lungs from the chemicals. Additionally, be sure to work in a well-ventilated area when using paint thinners and other solvents.
After removing the paint, scrub the area with warm water and detergent to remove any remaining chemicals or paint residue. Finally, dry the item and inspect it for any remaining stains. If necessary, use a non-abrasive all-purpose cleaner to remove any stubborn stains and restore the plastic to its original condition.

Soak in hot water with baking soda and vinegar
So, you want to strip back painted clear plastic using a combination of hot water, baking soda, and vinegar. Here's a detailed guide to help you with the process:
Firstly, gather your supplies. You'll need a pot or container large enough to submerge the plastic item, hot water, baking soda, vinegar, and a stirring utensil. It's also a good idea to have some tongs or heat-resistant gloves for handling the hot items and a scraping tool, such as a plastic scraper or a flexible metal scraper, for removing the paint. Remember to work in a well-ventilated area to avoid inhaling any vinegar fumes.
Now, let's prepare the stripping solution. Fill your pot or container with hot water. The water should be hot enough to help loosen the paint but not boiling, as you'll be handling the solution and submerging your plastic item in it. Add equal parts baking soda and vinegar to the water. The amount of these ingredients will depend on the size of your container and the number of items you plan to soak. Stir the solution well to ensure the baking soda is dissolved and distributed throughout the water.
Carefully place your painted plastic item into the hot solution. Use tongs or heat-resistant gloves to handle the item safely. Allow the plastic to soak for at least 15 minutes. The baking soda, hot water, and vinegar will work together to loosen the paint. For heavily painted items or if the paint is particularly stubborn, you may need to extend the soaking time or repeat the process.
Once the paint has loosened, remove the item from the solution using your tongs or heat-resistant gloves. Place the item on a suitable surface, such as an old tray, and let it cool down slightly. While the item is still warm, begin peeling and scraping off the loosened paint. Be gentle to avoid damaging the plastic surface. If needed, you can use a soft-bristled nylon brush to scrub away any remaining paint, but avoid metal brushes that can scratch the plastic.
Finally, wipe away any residue with a damp cloth, and let the item dry completely. If any paint patches remain stubborn, you can repeat the soaking process or try using a gentle paint stripper or solvent. Remember to always test any new solutions on an inconspicuous area of the plastic first to ensure it won't cause damage.

Use brake fluid
Brake fluid can be used as an alternative to paint stripper to remove paint from small plastic objects. It is a popular method in the wargaming and modelling community. The fluid must be left in contact with the model for an extended period, during which it loosens the paint, breaking down the adhesion between the paint and the model. It is important to note that brake fluid can cause softening in some types of plastic, so it should be tested on a small section of the plastic before use.
To begin the process, wash the object with mild liquid soap and warm water to remove any dirt, debris, or chemicals. Rinse it thoroughly and pat it dry with a paper towel. Next, pour the brake fluid into a glass jar that is large enough to fully submerge the item. Completely submerge the item in the fluid and leave it to soak. The length of time required will vary, but it could be up to 12 hours. If the paint is particularly stubborn, you can add fillers to the jar to ensure the fluid covers the component.
After soaking, scrub the object to remove the loosened paint. If the paint is still not coming off, submerge the object in the brake fluid again for another 12 hours and repeat the scrubbing process. Once the paint has been removed, wash the object with mild liquid soap and warm water again, and then pat it dry.
Brake fluid is a caustic chemical, so it is important to work in a well-ventilated area and wear protective clothing, such as rubber gloves and old clothes. Be careful not to splash the fluid on your bare skin.
