Soak in brake fluid, scrub with sandpaper
Removing enamel paint from plastic miniatures requires careful handling of chemicals and attention to detail. Here is a step-by-step guide for the process:
Step 1: Prepare the Workspace and Materials
Before beginning, ensure you have a well-ventilated workspace, as you will be dealing with chemicals. Cover your work area with newspaper or paper towels to protect the surface and aid in easy cleanup. Gather your materials: a glass jar or container with a lid, brake fluid, rubber gloves, old clothes, sandpaper, and a source of warm water. It is important to wear gloves and old clothing to protect your skin and body from the chemicals.
Step 2: Test Brake Fluid on a Small Section
Before submerging your miniature, test the brake fluid on a small, inconspicuous section of the plastic. Brush the fluid onto this area and let it sit for about two hours. Then, wipe it off with a paper towel and check for any signs of softening or damage to the plastic. If the plastic appears unaffected, you can proceed with the next step.
Step 3: Soak the Miniature in Brake Fluid
Pour brake fluid into your glass jar, ensuring you pour enough to completely submerge the miniature. Gently place the miniature into the jar, being careful not to splash the fluid on your skin. Close the lid and let the miniature soak. The duration of the soak may vary; some sources suggest 12 hours, while others recommend 24 hours for optimal results.
Step 4: Scrub with Sandpaper
After the soaking period, remove the miniature from the brake fluid and dispose of the fluid according to waste disposal regulations. Do not pour it down the drain. Using sandpaper, gently scrub the miniature to remove any remaining paint. Take care not to apply too much pressure to avoid damaging the miniature's surface. Rinse the miniature with warm water to remove any residual brake fluid and paint particles.
Step 5: Repeat if Necessary
If there is still paint remaining on the miniature, you may need to repeat the process. Soak the miniature in brake fluid again for a shorter duration, such as 3-6 hours, and then scrub with sandpaper. You can also try using a toothbrush to gently scrub the paint off, especially in hard-to-reach areas. Remember always to work carefully and patiently to avoid damaging your plastic miniature.

Soak in caustic soda and water
To remove enamel paint from plastic miniatures using caustic soda and water, you will need the following:
- Caustic soda (also known as lye or sodium hydroxide)
- Water
- A container with a lid (a plastic or glass container is best)
- A miniature with enamel paint you want to remove
- An old toothbrush
- Toothpicks
- Paper towels or old newspaper
First, prepare your caustic soda solution by dissolving an appropriate amount of caustic soda in water. The recommended concentration is 10% – that's one pound of caustic soda per gallon of water. Stir the mixture until the caustic soda has fully dissolved and the solution becomes a gel-like substance.
Next, detach the plastic base from your miniature if possible, as some chemicals can damage or soften the base. Place your miniature into the container and cover it with the lid. Allow the miniature to soak in the caustic soda solution. Depending on the paint thickness and the miniature's material, this process can take anywhere from three hours to a day.
Check on your miniature regularly to ensure the caustic soda solution is not damaging the model. If the paint has not softened after a day, try repeating the process or consider using a different method.
Once the paint has softened, use an old toothbrush to gently scrub away the loosened paint. For hard-to-reach areas, use toothpicks to carefully remove the remaining paint. Finally, rinse your miniature with clean water and dry it thoroughly.
Always exercise caution when working with corrosive substances like soda lye. It is recommended to wear protective gear, including gloves and eye protection, to avoid skin and eye contact with the corrosive solution.

Soak in Simple Green, brush off paint
To remove enamel paint from plastic miniatures, you can use a variety of chemical paint removers, including Simple Green. First, detach the plastic bases from the miniatures if possible, as some chemicals can damage the base. Then, find a suitable container with a lid, such as a plastic takeout box or a jar, and fill it with your chosen chemical paint remover. Place your miniatures inside, ensuring they are fully submerged, and secure the lid.
For Simple Green, you should soak your miniatures for about an hour. Then, remove them from the solution and use a toothbrush to brush off the loosened paint. It is recommended to use a hard toothbrush for this step, as softer ones may not be as effective. If there are small crevices or hard-to-reach spots, you can use toothpicks or pipe cleaners to get into these areas.
The process of removing enamel paint from plastic miniatures with Simple Green is relatively straightforward. Soaking the miniatures in the solution breaks down the paint, allowing it to be easily brushed off without damaging the plastic. This method is gentle and effective, making it a popular choice for removing paint from delicate models.
It is important to note that, while Simple Green is a gentle option, some paint may still stain the plastic. Additionally, depending on the thickness and age of the paint, you may need to repeat the process multiple times to fully remove it. In some cases, old paint or multiple layers of paint can be particularly challenging to remove, and you may need to accept that not all the paint will come off.

Soak in Biostrip, brush off paint
So, you've gotten some enamel paint on your plastic miniatures and are looking for a way to remove it. Well, you're in luck! There are a few methods you can try, one of which is using Biostrip. Here's a step-by-step guide on how to do it:
First, you'll need to gather your materials. You'll need a container with a lid, such as a plastic takeout box or a jar, some Biostrip, and an old toothbrush. It is also recommended to have some toothpicks and paper towels or old newspaper scraps to hand.
Next, you'll want to detach any plastic bases from your miniatures if possible, as some chemicals can damage or soften them. If you're unsure, it's a good idea to test the process on a throw-away model first to ensure your miniatures can withstand it.
Now, it's time to apply the Biostrip. Scoop some of the product out of its tub and use an old or cheap paintbrush to apply it to your miniature. Make sure to get it into all the nooks and crannies, and then let it sit for a couple of hours. You can also just dunk the miniature into the Biostrip, but this may leave some paint behind and degrade the surrounding stripping agent.
After a couple of hours, the paint should be loose and ready to come off. Take your miniature out of the Biostrip and use your toothbrush to gently scrub away the paint. If there are any hard-to-reach spots, you can use a toothpick to get into them.
Finally, give your miniature a rinse in some water to remove any residual Biostrip and paint. And that's it! Your miniature is now free of enamel paint and ready for a new coat.

Soak in isopropyl alcohol, cover, and leave
To remove enamel paint from plastic miniatures, one method is to use isopropyl alcohol. This method is inexpensive and effective, but it is important to be cautious as isopropyl alcohol is a volatile substance. Before you begin, ensure you have adequate ventilation in your workspace. You should also cover your work area with paper towels or old newspaper scraps to protect the surface from spilled solvent or splashed paint. Additionally, it is recommended to wear gloves to keep your hands clean and to improve your grip on the miniatures.
For this method, you will need at least three containers. One container will be used for soaking the miniatures in isopropyl alcohol, another for washing your brushes, and the third for organising your brushes and other tools. It is important to use a container with a lid for the soaking process, as isopropyl alcohol is volatile and has a strong odour. You can use plastic containers such as old food containers or glass jars, ensuring that they are thoroughly cleaned before use.
Once you have gathered your materials and prepared your workspace, you can begin the process of removing the enamel paint. Fill the first container with isopropyl alcohol, and gently place your miniatures into the solution. Ensure that the miniatures are completely submerged in the alcohol. Secure the lid on the container and leave it for around 20 minutes or longer for deeper paint penetration. The duration of the soaking process will depend on the thickness and number of paint coats on your miniatures.
While waiting, you can prepare your other containers. Fill one with water, which can be used for rinsing the miniatures after they have been soaked in the alcohol. The third container can be used for organising your brushes and other tools, such as toothbrushes and pipe cleaners, which will be useful for scrubbing away the loosened paint.
