Removing acrylic paint from plastic models can be a challenging task. Acrylic paints are harder to remove than enamel paints, which can be easily removed with white/mineral spirits. However, there are several methods that can be effective in removing acrylic paint. These include using an antiseptic solution like Dettol, oven cleaner, isopropyl alcohol, or a Revell or Humbrol-style brush cleaner. Each method requires soaking the model in the solution for a few hours, followed by scrubbing with a toothbrush and washing liquid. It is important to prepare the workspace with proper ventilation, gloves, and rags before attempting to remove paint. After removing the paint, a fresh coat of paint can be applied to the model for a more even surface.

What You'll Learn
Soak in Dettol or antiseptic solution
Soaking in Dettol or an antiseptic solution is an effective way to remove acrylic paint from plastic models. This method is simple and quick, and it does not damage the structure of the model.
To start, you will need to mix your Dettol solution. Generally, a 1:1 ratio of Dettol to cold tap water is recommended, but you can adjust the concentration according to your needs. For a stronger solution, you can use less water, but keep in mind that the model will need to soak for a longer period. On the other hand, a higher water ratio will require a longer soaking time.
Once you have prepared your solution, find a suitable container that is made of glass or plastic. The container should be large enough to submerge the model completely. Place the model into the container and ensure it is fully immersed in the solution. Leave the model to soak for 12 to 24 hours, or even up to 30 hours for multiple layers of paint.
After the allotted time has passed, you will notice that the paint has lifted and bubbled. At this stage, you can simply brush or rub off the remaining paint with a toothbrush or a similar tool. It is advised to wear latex gloves when handling the model and the solution, as they can be irritants to the skin.
While this method is effective for removing paint, it is important to note that it may loosen the joints of modelling putty or super glue. Therefore, it is recommended to only use this method if you do not need to keep the model in one piece with these adhesives. Additionally, always follow the safety instructions on the product labels.

Use oven cleaner
Oven cleaner can be used to remove acrylic paint from plastic models. This method is considered "impromptu", but it can be effective. It is important to note that oven cleaners can be irritants, so it is recommended to use latex gloves when handling them. Adequate ventilation is also important when working with oven cleaners.
There are two main ways to use oven cleaner to remove acrylic paint from plastic models. The first method involves spraying the foam cleaner directly onto the model and then placing the model in a ziplock bag for one to two days. This allows the oven cleaner to break down the paint, making it easier to remove.
The second method involves spraying the oven cleaner into a cup and then using a toothbrush to scrub it onto the model. This method is more targeted and allows for more control over the application of the oven cleaner. It is important to be gentle when scrubbing to avoid damaging the plastic model.
After applying the oven cleaner, it is important to rinse the model thoroughly with water to remove any residual oven cleaner. This will ensure that the plastic model is safe to handle and that no cleaner residue is left behind.
It is worth noting that oven cleaners may not work for all types of acrylic paint and plastic models. The effectiveness of this method may depend on the specific paint and plastic used, as well as the condition of the paint. It is always a good idea to test the oven cleaner on a small, inconspicuous area of the model first to ensure that it does not cause any damage.

Try Simple Green all-purpose cleaner
Removing acrylic paint from a plastic model can be challenging, but one effective method is to use Simple Green all-purpose cleaner. This product is a great option for those who want to avoid more corrosive paint removers. It is also cost-effective and easily accessible.
To use Simple Green all-purpose cleaner for paint removal, start by filling a container with enough of the cleaner to completely submerge the model. Then, dunk the model parts into the cleaner and let them soak for a few days. This will loosen the paint, making it easier to remove.
After a few days of soaking, take a toothbrush and gently scrub the paint. Pay extra attention to corners and small details, as these areas can be more challenging to clean. Rinse the model with water and inspect it for any remaining paint. If necessary, repeat the process until all the paint is removed.
It is important to exercise caution when handling any chemicals. Always wear gloves and protective eyewear when working with paint removers. Additionally, ensure that the work area is well-ventilated to avoid inhaling any fumes.
Once the paint has been successfully removed, it is recommended to apply a fresh coat of paint to the model. This will help to enhance the appearance and ensure a uniform finish.

Soak in isopropyl alcohol
Removing acrylic paint from plastic models can be challenging, but there are some effective methods to try. One recommended method is to use isopropyl alcohol, a solvent that works well to remove acrylic paint. Here is a step-by-step guide on how to do it:
Prepare the Isopropyl Alcohol Solution
Firstly, ensure you have the correct type of alcohol. Isopropyl alcohol, often referred to as rubbing alcohol, is readily available at pharmacies and hardware stores. Check the label and ensure it has a concentration of 91% or above for optimal results.
Test for Plastic Safety
Before applying the alcohol to the model, it is crucial to test it on a small, inconspicuous area of the plastic to ensure it won't cause damage or disfigurement. This is an important step as some plastics can be sensitive to certain solvents.
Soak the Model
Once you've confirmed the isopropyl alcohol is safe to use on your model, it's time to soak the painted areas. Pour the alcohol into a container, ensuring the volume is sufficient to submerge the model or its relevant parts. Gently place the model into the container, being careful not to handle it too roughly or apply excessive force that could cause breakage. Allow the model to soak for 1 to 3 hours. The duration of the soak will depend on the severity of the paint adhesion; more stubborn paint may require a longer soak.
Remove and Rinse the Model
After the allotted soaking time, carefully remove the model from the container, pouring the used alcohol solution down the drain. It is advisable to wear gloves during this process to protect your skin from the solvent. Rinse the model under lukewarm water to neutralize any remaining alcohol residue, ensuring you target areas where the paint was present.
Scrape Away Paint Residue
Gently scrape away any remaining paint residue using a plastic scraper or your fingernail, especially effective for curved surfaces. Hold the scraping tool at a slight angle and gently work it under the painted surface to lift and remove the paint. If necessary, repeat the soaking and scraping process until you've removed all the paint.
Final Rinse and Inspection
Give the model a final rinse under lukewarm water to ensure no alcohol or paint residue remains. Gently shake or tap the model to remove any excess water, and then allow it to air-dry. Once dry, inspect the model for any lingering paint traces and ensure the plastic surface is intact, with no signs of damage or disfigurement.
Remember always to be cautious when working with solvents, and if all else fails, consider seeking advice from modelling forums or experts for alternative methods or brand-specific recommendations.
