Stripping paint off plastic minis can be done in several ways, but it's important to be cautious to avoid damaging the plastic. Soaking minis in isopropyl alcohol, Simple Green, or hot water can effectively remove paint. However, the duration of soaking and the concentration of alcohol are critical to avoid softening or melting the plastic. After soaking, scrubbing with a toothbrush helps remove stubborn paint. Other methods include using Windex, Dettol, or Pine-Sol, but proper ventilation is crucial due to strong fumes. Additionally, IPA is effective but should be used in intervals to avoid softening resin details.

Soak in isopropyl alcohol
So, you've got some plastic minis that you want to strip paint from, and you're thinking of using isopropyl alcohol to do the job. Well, you've come to the right place! Here's a step-by-step guide on how to strip paint from plastic minis using isopropyl alcohol:
First things first, make sure you have the right type of isopropyl alcohol. You'll want to get your hands on some 91% isopropyl alcohol; the 70% version is too weak, and the 99% version is too strong. Head to your local drug store and pick up two pints (roughly 2L) – you can usually find it on the bottom shelf near the bandages. A word of warning: isopropyl alcohol is flammable and can be dangerous, so make sure you follow all the safety precautions on the bottle. Always wear gloves when handling it, as it can be harmful to your skin.
Now that you've got the right supplies, it's time to start stripping that paint! Begin by filling a large bowl or container with the isopropyl alcohol. You'll want to make sure the container is deep enough to completely submerge your minis. Gently place them into the alcohol, being careful not to splash. Leave them to soak for about 10 minutes. The alcohol will start to break down the paint, making it easier to remove.
After the first soak, take your minis out of the alcohol and give them a soft scrub with a toothbrush. Make sure the toothbrush is rinsed off before you start scrubbing. You should start to see the primer coming off, revealing the original grey plastic underneath. If the paint is particularly stubborn, you can give them another soak for 5-10 minutes and then scrub again. Be careful not to overdo it, though – too much soaking and scrubbing can damage the details on your minis.
Once you've removed all the paint, give your minis a final rinse and set them on some paper towels to dry. Leave them for at least 3-4 hours to make sure they're completely dry before you attempt to prime and paint them again. If you want to be extra cautious, you can leave them to dry for 24 hours.
And that's it! You've successfully stripped the paint from your plastic minis using isopropyl alcohol. Now you can get creative and give them a brand-new look. Just remember to always put safety first when working with chemicals and have fun with your new projects!

Scrub with toothbrush
Scrubbing with a toothbrush is a common method used to strip paint off plastic minis. It is important to note that the toothbrush should be a classic toothbrush with bristles only and not one with plastic bits for cleaning the tongue. An electric toothbrush can also be used.
To start, put on gloves to protect your skin and ensure that the area is well-ventilated or wear a mask to avoid inhaling any fumes. Next, place the plastic mini in a container filled with a suitable cleaning solution. Common cleaning solutions used include Simple Green, Super Clean, isopropyl alcohol, and water. The choice of solution depends on the type of paint and the desired level of cleanliness. For example, if you are dealing with water-based acrylic paint, warm water may be sufficient, while tougher paint jobs may require stronger solutions like isopropyl alcohol.
After letting the mini soak for the recommended time, which can range from a few minutes to several days depending on the solution, remove it from the container. Then, dip your toothbrush in the cleaning solution or water and start scrubbing the paint off. It is recommended to scrub over a towel to catch the paint flakes and avoid making a mess.
While scrubbing, focus on getting into the recesses and crevices of the mini, as these areas may require more attention. Be aware that some paint, especially in detailed areas, may be challenging to remove completely. Additionally, certain solutions can also remove glue, so you might need to re-glue some parts after the process.
Finally, once you have removed as much paint as possible, rinse the mini under hot water while continuing to scrub. This will help remove any remaining residue and ensure a clean surface for repainting.

Use Simple Green
Simple Green is a cleaner that can be used to strip paint off plastic minis. It is a safer alternative to other stripping agents like acetone, which can damage plastic models. While Simple Green is effective, it may not be as strong as other products, and users have reported mixed results when using it.
To strip paint off plastic minis using Simple Green, start by placing the minis in a container of undiluted Simple Green. The duration of the soak will depend on the thickness of the paint. For thick layers of paint, an initial soak of up to one week may be required. After the initial soak, scrub each mini under hot running water using a stiff-bristled brush for about 3 minutes. This process may need to be repeated for heavily painted minis, with a soak, strip, soak, strip cycle.
It is important to note that Simple Green may also remove primer from the plastic minis, so be prepared to re-prime the minis before repainting. Additionally, always wear gloves and work in a well-ventilated area when using Simple Green, as with any other chemical product.
Simple Green is a readily available product that can be found in most hardware stores or the cleaning aisle of Walmart. It is also available in Canada, where it may be easier to find Super Clean, which is reported to work just as well.

Avoid paint thinners
It is important to avoid paint thinners when stripping paint off plastic minis as they can melt the plastic. Paint thinners are suitable for use on metal miniatures, but not plastic ones.
There are several alternative methods to remove paint from plastic minis. One option is to use a cleaning solution such as Simple Green, which can be left to soak for up to 24 hours before scrubbing the paint off with a toothbrush. Other cleaning solutions that can be used include Dettol, LA's Totally Awesome, and Biostrip. It is also possible to use household products such as Original Pine flavour Pinesol, which can be soaked overnight and then scrubbed with a toothbrush.
Another alternative to paint thinners is to use alcohol. This can be 95° alcohol used for home cleaning or isopropyl alcohol. The minis should be left to soak overnight in a closed container, as alcohol evaporates, and then cleaned with a toothbrush. It is important to wear gloves and work in a well-ventilated area when using alcohol, as it can be dangerous.
A third option is to use an ammonia-based solution such as Windex, which can help to peel paint off minis. This method is cheap and does not leave a strong smell. The mini should be soaked in a Windex and water solution and then scrubbed with a brush.
Finally, for water-based acrylic paint, minis can be soaked in warm water for 30 minutes and then scrubbed with a toothbrush to remove the paint.

Work in a well-ventilated area
Stripping paint off plastic minis often involves using chemicals, such as isopropyl alcohol, Simple Green, or Dettol. These products can produce strong fumes, so it is important to work in a well-ventilated area to avoid inhaling them.
To ensure adequate ventilation, open all windows and exterior doors in the room. If the room has no windows, open the door and place a box fan in the doorway to pull fresh air into the room and force out the paint-fumed air. Another option is to set up a couple of box fans in the room, one pulling fresh air in and the other pushing stale air out. If possible, also use the house's central ventilation system to increase airflow.
If you are unable to ventilate the room sufficiently, consider wearing a respirator or a proper filtration mask to avoid inhaling paint fumes. Even if you are working in a well-ventilated area, it is still recommended to wear a mask as an extra precaution.
Additionally, be mindful of the products you are using and follow any safety instructions on their labels. Some paints and thinners can be irritants and cause dizziness or headaches when inhaled, while others may lead to respiratory issues or more serious long-term health problems. Always use your best judgment and take the necessary precautions to ensure a safe working environment.
