What You'll Learn
Use a plastic card or scraper to chip off the paint
If you want to remove paint from a plastic screen, one method you can try is using a plastic card or scraper to chip off the paint. This method is ideal for small spots of paint, which can be removed without taking the screen out of the window.
First, it is important to identify the type of paint and plastic you are dealing with. Water-based paints, such as latex or acrylic, tend to have a duller sheen and fade over time, while oil-based paints are glossier and yellow as they age. The type of plastic could be ABS, acrylic, polyethylene, or nylon. Knowing the materials you are working with will help you choose the safest tools and products to use.
Next, if the paint is still wet, simply use a soft cloth to blot up as much of it as possible. If the paint is dry, you can try softening it with warm soapy water, olive oil, or a product like Goof-Off or Methyl Ethyl Keytone (MEK). These products are solvents that dissolve water-based paint and evaporate quickly, but they can also soften the screen material, so be sure to test them on a small area first. You can also try using a heat gun to soften the paint, but be careful not to melt the plastic.
Once the paint is softened, hold the plastic card or scraper at a slight angle and gently push it under the painted surface. Work slowly and carefully to avoid damaging the screen. If the paint is particularly difficult to remove, you may need to use a stronger solvent or paint stripper, but always test these products on a small area first to ensure they won't damage the plastic.

Try a paint thinner, nail polish remover, or alcohol
Removing paint from a plastic screen can be tricky, and it's important to proceed with caution to avoid damaging the plastic. Before attempting any of these methods, it is recommended to test the chosen solvent on a small, unseen area of the plastic to ensure it does not cause damage.
Paint thinner
Paint thinner can be an effective way to remove paint from plastic, but it is important to note that it may not work on dried paint. To use this method, allow the paint thinner to soak into the paint, then remove it with a tool such as a paint scraper, razor blade, or plastic putty knife. Be careful not to apply too much pressure, as this may scratch the plastic. It is also important to work in a well-ventilated area and wear protective gear, such as rubber gloves and an apron, when using paint thinner to avoid contact with the skin.
Nail polish remover
Nail polish remover is often just acetone, which can be effective in removing paint from plastic. However, acetone is a strong solvent that can damage or melt certain types of plastic, so it should be used with caution. To use this method, pour enough nail polish remover to cover the affected area, then rub and wipe with a clean rag or paper towels, repeating as necessary until the paint is gone.
Alcohol
Rubbing alcohol, or isopropyl alcohol, can be an effective and gentle way to remove paint from plastic without melting it. It is important to wear protective gear, such as gloves and a face mask, when using rubbing alcohol to protect the skin and avoid inhaling fumes. Pour the alcohol over the paint and scrub firmly with a rag until the paint begins to disappear. For small items, place them in a container with the alcohol for 1 to 3 hours, then scrape the paint off with a tool. After using any of these methods, it is important to clean the area with soapy water or a high-quality cleanser to remove any leftover paint residue.

Use a strong detergent like trisodium phosphate
Trisodium phosphate (TSP) is a powerful cleaning agent that can be used to remove paint from a plastic screen. It is an inorganic chemical compound that takes the form of a white granular or crystalline substance. TSP is typically sold in powder form and should be stored in a secure, dry place to prevent clumping.
When using TSP, it is important to take precautions as it is toxic and may not be legal in your area. It can be harmful to humans, pets, plants, and aquatic life, so it is recommended to wear long pants and sleeves, waterproof gloves, goggles, and a respirator when preparing and using it. It can also damage many common household surfaces, so it should not be used on glass, metal, or ceramic tiles.
To use TSP to remove paint from a plastic screen, mix 1/2 cup of TSP with a gallon of warm water to create a cleaning solution. Soak a kitchen scrubber in the solution and wash the screen, supporting one side of the screen with a rag while you scrub the other side. This method should remove most of the paint, but if not, a solvent may be needed.
It is important to note that TSP will remove the sheen from glossy painted surfaces, so it may not be suitable for all plastic screens. It is always a good idea to test it on a small, inconspicuous area first to ensure it does not damage the surface.

Soak a rag in isopropyl alcohol or lacquer thinner
To remove paint from a plastic screen, one method is to soak a rag in isopropyl alcohol or lacquer thinner. This method is particularly effective for removing dried latex paint or oil-based paint, respectively.
When using isopropyl alcohol, it is important to wear rubber gloves and goggles, as the chemical is quite flammable. The process involves supporting one side of the screen with a cloth or rag while you rub the other side with the alcohol-soaked rag. Keep the rag damp but not moist, and rub in short bursts to avoid saturating the screen material with solvent and potentially damaging it. Each time you stop, let the solvent evaporate before continuing.
Similarly, when using lacquer thinner, it is crucial to prioritize safety. Wear chemical-resistant goggles and gloves, as well as breathing protection, as this substance is hazardous. Work in a well-ventilated area to avoid inhaling volatile organic compounds (VOCs). Like isopropyl alcohol, apply the lacquer thinner by supporting one side of the screen and rubbing the other side with the soaked rag.
Before attempting to remove paint from a plastic screen using isopropyl alcohol or lacquer thinner, it is recommended to test a small area first. This can be done by applying the substance to a corner of the screen and allowing it to dry. If there is no damage, proceed with caution, following the above instructions.

Use a plastic putty knife to scrape off wrinkled paint
If you have wrinkled paint on a plastic screen, one way to remove it is by using a plastic putty knife to scrape it off. This is a good method if the paint spots are large.
Begin by removing the screen from the window, if possible, to get easier access to the paint. If the paint is still wet, you can blot it with an absorbent cloth. If the paint has dried, you can skip this step.
Next, use a plastic putty knife to gently scrape off as much paint as possible. The plastic putty knife is a good option for this task as it has a fine edge, making it easy to lodge under the paint without scratching the plastic screen. Its long, flexible handle also provides good leverage and keeps your hand clean.
If there is any remaining paint on the screen after scraping, you can try using a paint thinner, nail polish remover, or isopropyl alcohol on a soft cloth to gently rub and remove the remaining paint. Alternatively, you can use a damp cloth to wipe the screen and keep it moist, which may help to soften the paint and make it easier to remove with the plastic putty knife.
