What You'll Learn
Use isopropyl alcohol to break down the paint
Isopropyl alcohol can be used to effectively break down and remove acrylic paint from plastic. It is a good option for removing paint from plastic because, unlike acetone, it can be used on plastics and synthetic fabrics. It is also a more accessible option than acetone, as it is commonly found in rubbing alcohol, which is available at pharmacies and drugstores.
To remove acrylic paint from plastic using isopropyl alcohol, start by pouring the alcohol directly onto the painted area. Allow the alcohol to sit for a few minutes to let it start breaking down the paint. Then, use a toothbrush or a butter knife to gently scrape away the paint. It may take several applications of alcohol and scraping to fully remove the paint. This method is most effective when the paint is still fresh, so it is important to act quickly when trying to remove acrylic paint from any surface.
In addition to isopropyl alcohol, there are other liquids that can be used to remove acrylic paint from plastic. These include organic solvents, such as lacquer thinner, which can be used to remove paint from hard-to-reach areas. However, it should be noted that lacquer thinner often contains toxic chemicals, so it should be used outdoors and with caution. Another option is to use a simple spray bottle of Simple Green, which can be sprayed onto the paint and left to sit before being scrubbed off with a toothbrush.
While isopropyl alcohol is a useful tool for removing acrylic paint, it is important to note that it may not be as effective on all colours. This is because the alcohol reacts differently with organic and inorganic pigments. For example, organic pigments like phthalos, quinacridones, and hansas are less dense than inorganic pigments like Ultramarine Blue and Earth Colors. Therefore, the type of pigment used in the paint may impact the effectiveness of isopropyl alcohol as a paint remover.

Scrape off the paint with a tool
Scraping off dried acrylic paint can be a tedious task, but with the right tools and techniques, the process can be more manageable and effective. Here are some detailed instructions to help you scrape off the acrylic paint from plastic:
Choose the Right Tool:
Select a suitable scraping tool for the job. A plastic scraper is ideal for scraping off paint from plastic surfaces as it won't scratch the material underneath. Alternatively, a butter knife can be used, but be cautious as it may not be as gentle on the surface.
Prepare the Paint:
Before you start scraping, it's essential to loosen the paint to make it easier to remove. You can use a variety of solvents for this purpose, such as isopropyl alcohol, rubbing alcohol, or even a simple solution of warm water and soap. Apply the chosen solvent to the painted area and let it sit for a while to soften the paint.
Start Scraping:
Once the paint has been sufficiently loosened, begin scraping it off carefully. Work in small sections at a time, applying gentle pressure with your chosen tool. Be cautious not to scratch the plastic surface underneath. It's important to work slowly and patiently, as rushing the process may damage the plastic.
Repeat as Needed:
Scraping off acrylic paint may require multiple attempts, depending on the thickness of the paint and the size of the painted area. After each scraping session, wipe away the loosened paint with a damp cloth or paper towel. If necessary, reapply the solvent and let it sit again before continuing to scrape.
Finish with a Clean:
Once you've removed as much paint as possible, finish the job by giving the plastic surface a thorough cleaning. Use a mild detergent or soap and warm water to remove any remaining paint residue and solvent. Dry the surface with a soft cloth, and your plastic will be free of acrylic paint!
Remember, always work in a well-ventilated area when using solvents, and wear protective gear such as gloves and eye protection if necessary.

Wash with hot soapy water
To strip acrylic paint from plastic, one method is to wash the painted surface with hot soapy water. This method is tried and tested on a classroom wall, although it is a slow process. The wall can be pre-soaked with hot soapy water and scrubbed with a scrubber to remove the acrylic paint. This method is preferable to using acetone, which may ruin the underlying coats of paint.
A faster method is to use isopropyl alcohol, which will quickly and easily remove the paint without damaging the underlying paint. This can be done by wiping the alcohol onto the wall with a microfiber cloth. The alcohol can be applied with a spray bottle, and the wall can be wetted with paper towels to help retain moisture. However, it is important to note that alcohol may not be suitable for all surfaces, so it is recommended to test it on a small area first.
Another method for removing acrylic paint from fabric is to use laundry soap and sunflower oil. The paint can be wiped off with a damp sponge, and the fabric can be soaked in warm water for 15 minutes before being washed by hand or in a washing machine. It is important to act quickly, as acrylic paint dries reasonably fast and becomes water-resistant, making it difficult to remove.
Baking soda can also be used to remove wet or dry acrylic stains. It is mixed with dish soap and rubbing alcohol, and the paste is left on the stain for 15 minutes before being rinsed with soap and water. Hairspray can also be used, but it may damage some fabrics, so it is recommended to try another method first.

Use a solvent like acetone
If you want to strip acrylic paint from plastic, you can use a solvent like acetone. Acetone is a powerful solvent that can be used to remove acrylic paint from surfaces. However, it is important to note that acetone cannot be used on plastic as it will melt the plastic. Instead, acetone is mainly used on non-porous surfaces such as glass and metal.
Acetone is a common solvent used with fibreglass resins and can be found in most hardware stores, paint stores, and home improvement centres, usually packaged in metal tins. It is incredibly flammable but has low toxicity. To use acetone, you can soak a cloth or brush in the solvent and then apply it to the paint you want to remove. This method is especially useful for getting into hard-to-reach areas where scrubbing is not possible.
Another similar option is lacquer thinner, which is a more robust solvent blend that effectively removes acrylic paint from glass and metal. However, lacquer thinner often contains toxic chemicals like toluene and methanol, so it should only be used outdoors. Newer "green" formulations of lacquer thinner have replaced toluene with ethyl acetate, a low-toxicity solvent with a pleasant, fruity odour.
In addition to acetone and lacquer thinner, other organic solvents can be used to remove acrylic paint from plastic. For example, isopropyl alcohol can effectively remove acrylic paint without damaging the underlying surface. This method is suitable for painted walls, as it will not affect the paint underneath.
While acetone and other solvents are effective in removing acrylic paint, it is important to exercise caution when working with these chemicals. Always work in a well-ventilated area and follow the instructions on the product label to ensure safe and proper usage.

Use a steam iron for fabrics
To strip acrylic paint from fabrics, a steaming iron or steam generator can be used. Before using a steam iron, pre-moisten the acrylic stains with soapy water. It is also important to note that the paint should be removed from fabrics before it dries. If the paint has dried, a steam cleaner can be used to soften the paint, which can then be gently scraped off.
When using a steam iron, it is recommended to put a scrap piece of fabric between the painted fabric and the iron to ensure that no paint is transferred to the iron. Alternatively, the fabric can be turned inside out and ironed on the non-painted side. The iron should be set to a medium to hot setting, depending on the type of fabric. It is also important to turn off any steam settings and empty the water container to ensure that the fabric is exposed to dry heat.
The fabric should be ironed for at least two minutes, but ideally for three to five minutes. Ironing for a longer period can help ensure that the paint is truly set into the fabric and prevent it from washing out or running. It is recommended to iron relatively small sections at a time to prevent scorching the fabric.
After ironing, it is important to allow the fabric to cool down before handling it. Additionally, it is suggested to wait about a week or so before washing the fabric again to ensure the paint is truly set.
