Removing acrylic paint from frosted plastic can be challenging, but several methods can be effective. One option is to use a paint stripper or oven cleaner, which can be applied and left to sit for a few hours or even overnight. The paint can then be scrubbed off with a toothbrush. Another option is to use an antiseptic solution like Dettol, which can help remove water-based acrylic paint. For a more natural approach, sandpaper can be used to gently remove the paint, but this must be done carefully to avoid damaging the plastic. Finally, some chemical solvents can be used to remove paint, but these may require multiple applications and can leave the surface cloudy.

What You'll Learn
Use a paint stripper
If you want to remove acrylic paint from frosted plastic, one method you can use is a paint stripper. It is important to note that different types of plastics require different care, so it is necessary to identify the type of plastic you are working with before starting. Some paint strippers can damage certain plastics, so it is recommended to try products with less potential to damage the plastic first and then move on to stronger options if needed.
There are various types of paint strippers available, including toxic and non-toxic options. Toxic paint strippers are stronger and can remove paint more effectively, but they can also be dangerous and require the use of gloves, eye protection, and a respirator. Non-toxic paint strippers, such as citrus-based gel paint removers, are safer to use but may work more slowly and may not be as effective on certain types of paint.
To use a paint stripper, spread a small amount onto the painted area and let it sit for several hours or overnight. The paint stripper will cause the surface paint to wrinkle. After this, use a tool such as an old toothbrush or a paint scraper to brush or scrape the paint off. If necessary, use fine sandpaper to sand the surface, followed by a plastic rubbing compound and plastic polish to restore shine and clarity.
In addition to paint strippers, there are also other solvents that can be used to remove paint from plastic, such as acetone, nail polish remover, and rubbing alcohol. However, some of these may damage the plastic, so it is important to test on a small area first or choose a solvent that is known to be safe for use on plastic.

Polish with a product like Novus
Once you've removed the paint from the frosted plastic, it's time to polish the surface to restore its shine and clarity. Novus Plastic Polish is a popular product that can help you achieve this. Novus is a well-known brand that offers a range of plastic polish and restorer products, specifically designed for use on plastic, acrylic, and fibreglass items. Their products are suitable for both home and industrial applications.
Novus Plastic Polish can be purchased online through their website, with shipping available worldwide. However, it's important to note that international orders outside of the US and Canada may take up to 14-28 business days to arrive. You can also find Novus products in hardware stores and auto parts stores, depending on your location.
Now, let's get into the polishing process. Novus offers a 2-oz Plastic Polish Kit, which includes everything you need to revive and restore your plastic items. Before you begin, it's always a good idea to test the product on a small, inconspicuous area to ensure it doesn't cause any discolouration or damage.
Start by shaking the bottle of Novus No. 2 thoroughly. Then, apply a liberal amount of the product to a clean, soft cloth. Polish the surface using a firm back-and-forth motion, focusing on the areas with scratches. Keep the cloth saturated with polish throughout this process. Once you've addressed the most prominent scratches, reapply Novus No. 2 uniformly in circular motions across the entire surface, using short strokes and light pressure. Allow the polish to dry, and you'll notice a light haze forming.
Finally, grab a clean section of the cloth and buff the surface using firm, short strokes. This buffing step is crucial to achieving the best results and a glossy finish. For heavy scratches, you may need to apply additional coats of Novus No. 2 or even Novus No. 3. To complete the process and achieve optimal results, follow up with Novus No. 1.

Use acetone and T-cut for clarity
If you want to remove acrylic paint from frosted plastic, a little acetone on a rag will take the paint off. However, it will likely leave the plastic surface cloudy. To restore the plastic's clarity, you can polish it with T-cut.
Acetone is a powerful solvent that can be used to remove paint from a variety of surfaces. It is important to be cautious when using acetone, as it can be harmful if inhaled or ingested. Make sure to use it in a well-ventilated area and avoid breathing in the fumes. Also, keep it away from your skin and eyes, as it can be irritating.
Before applying the acetone, test it on a small, inconspicuous area of the plastic to ensure that it does not damage or discolour the surface. If the plastic passes the test, proceed by soaking a rag in acetone and gently rubbing it on the painted areas in a circular motion. The paint should start to come off. You may need to apply a little pressure and repeat the process a few times to completely remove the paint.
Once you have removed the paint, the plastic surface may appear cloudy or hazy. To restore its clarity, you can use a product called T-cut. T-cut is a polishing compound designed to remove light scratches and haze from various surfaces, including plastic. It will help to buff out any cloudiness left by the acetone and restore the plastic to its original clarity.
After using T-cut, you may need to apply a plastic polish to fully restore the shine. This will help to protect the plastic surface and maintain its clarity.

Try brake fluid
If you're looking to remove acrylic paint from frosted plastic, one method you can try is using brake fluid. This method is commonly used in the wargaming and modelling community to remove paint from small metal or plastic objects.
Brake fluid can serve as an alternative to paint stripper. When left in contact with the model for an extended period, it loosens the paint, breaking down the adhesion between the paint and the model. This process works well for lead and lead-free metal alloys, but it can also be used on plastic models with caution. It's important to note that brake fluid can cause softening in some types of plastic, so it's recommended to test it on a small section of the plastic before proceeding. Simply brush the fluid onto a small area, let it sit for two hours, then wipe it off with a paper towel. If you notice any signs of plastic coming away or softening, do not use the fluid for paint removal.
To use brake fluid for paint removal, start by pouring the fluid into a glass jar that is large enough to fully submerge the item you're stripping. Make sure to use DOT3 or DOT4 brake fluid, as DOT5 is silicone-based and may not be effective for paint removal. Submerge the item in the fluid and let it soak for an extended period, such as overnight or for 12 hours. The paint should start to wrinkle and loosen. If needed, use an old toothbrush dipped in brake fluid to scrub away any remaining paint.
After successfully removing the paint, it's important to properly dispose of the brake fluid according to waste disposal regulations. Brake fluid is a caustic chemical, so wear rubber gloves and old clothes and work in a well-ventilated area to avoid splashing it on your skin. Additionally, be cautious when handling brake fluid as it contains a highly toxic alcohol (diethylene glycol) that can be dangerous if ingested.

Apply a solvent to burn the paint
To remove paint from plastic, you can use a variety of solvents. However, it is important to identify the type of plastic and paint before choosing a solvent, as certain types of plastic may react poorly to some solvents. For instance, thinner polyethylene, polypropylene, acrylic, and fibreglass may allow you to remove paint from their surfaces with stronger solvents.
Before using any solvent, be sure to test it in an inconspicuous area to ensure it won't damage the plastic. You can do this by applying a small amount of the solvent to a cotton swab or paintbrush and placing it on a small area of the plastic. Wait a few minutes, then rinse it off. If the plastic changes colour or texture, or indents when you press your fingernail into it, choose a different solvent.
If you are removing paint from a large plastic surface, such as polycarbonate, it is best to use a professional paint remover. These products are designed to remove unwanted paint and encapsulate dangerous ingredients like lead. When handling these types of solvents, be sure to wear protective gear, including rubber gloves and an apron, and work in a well-ventilated area.
For smaller items with paint splatters, you can use nail polish remover or anything with acetate. Rubbing alcohol can also be effective in removing paint from small plastic items. Simply apply the solvent to the painted area with a cotton ball and rub until the paint is gone. Place small items in a container with the solvent for one to three hours, then scrape off any remaining paint with a plastic scraper or your fingernail.
Other solvents that can be used to remove paint from plastic include paint thinner, mineral spirits, lighter fluid, and gasoline. However, these solvents may be more suitable for removing oil-based paints. Always be cautious when using solvents, as they can be toxic and damaging to certain types of plastic.
