What You'll Learn
Use isopropyl alcohol to strip paint
Stripping paint from plastic models can be done using isopropyl alcohol, which is an excellent cleaner and inexpensive solvent. It is a great option because it is unreactive and will not damage the plastic. It is also easily accessible, as it can be purchased at a drug store.
Before you begin, ensure you have the right supplies to avoid damaging your model. You will need at least three containers: one for stripping, one for washing brushes, and another for organizing brushes. You should also have paper towels, rags, and towels to keep your workspace clean and address spills quickly. Wear gloves to protect your skin from the alcohol and to ensure a steady hold on the model.
Once you have gathered your supplies, you can begin the process of stripping the paint. First, submerge the model in the isopropyl alcohol. You may need to leave it to soak for a couple of hours. Then, use a toothbrush to scrub the paint away. Rinse the brush frequently to clear the colour residue. You may need to repeat the process if there are multiple coats of paint or hard finishes.
It is important to note that isopropyl alcohol will only dissolve natural resin. It will not dissolve plastic glue or super glue. If your model has delicate resin, only strip a tiny part of the model at a time to avoid damage.

Prepare your workspace
Before you begin stripping paint from your plastic models, it is important to prepare your workspace thoroughly. This will ensure that you can work efficiently and safely, and it will also protect your work area from any potential damage or mess. Here are some detailed instructions to help you prepare your workspace:
Firstly, choose a suitable work area. It is recommended to work in a well-ventilated space, as some paint strippers can release strong fumes. Make sure you have enough room to lay out all your tools and containers and move your arms freely. Cover your work surface with old towels or rags to protect it from spills and damage. Have some paper towels or absorbent cloths within easy reach to deal with any accidental spills quickly and efficiently.
Next, gather and prepare your containers. You will need at least three containers: one for stripping, one for washing brushes, and one for organizing your brushes and other tools. Fill one container with 99.9% pure isopropyl alcohol, which is an effective and inexpensive solvent for removing paint from plastic models. You can find this at most hardware or paint stores. Fill another container with water, and leave the third one empty. Ensure that all containers are easily accessible and stable to avoid any accidental spills.
Additionally, prepare a pair of gloves to protect your skin from the chemicals and keep your hands dry and clean throughout the process. You may also want to wear protective clothing, such as an apron or a lab coat, to avoid getting paint stripper on your clothes. If you are working with small pieces, have a container or tray ready to organize them as you remove them from the model. This will help you keep track of all the parts and avoid losing anything.
Finally, gather the necessary tools for the paint removal process. You will need a variety of brushes, including toothbrushes and fine-detail brushes, to scrub and strip the paint. If you plan to soak the model in the paint stripper, prepare a lid or covering for the container to prevent evaporation and reduce fumes. You may also want to have some additional tools, such as tweezers or tongs, to handle small pieces safely.
By following these instructions, you will have a clean, organized, and safe workspace for stripping paint from your plastic models. Remember to take your time, work carefully, and always prioritize your safety when working with chemicals.

Use a toothbrush to scrub
Using a toothbrush to scrub is a great way to strip paint from plastic models without damaging the plastic. This method is suitable for both large and precise areas. It is also inexpensive and simple to execute.
Firstly, you will need to gather the right supplies. These include a classic toothbrush with simple bristles, a container, gloves, and a disinfectant or paint-removing solution. Dettol, a common household disinfectant, is a popular choice for this purpose. You can also use 99.9% pure isopropyl alcohol, which is inexpensive and easily available. If you are in the US, Walmart sells Krud Kutter Graffiti Remover, which is another effective option.
Once you have your supplies, create a mixture of equal parts disinfectant and cold water, or follow the instructions on your chosen paint-removing solution. Place your plastic model into the container and gently pour the mixture over it, fully submerging the model. Allow the model to soak for 24 to 48 hours, depending on the thickness of the paint and the type of undercoat.
After the model has soaked sufficiently, remove it from the solution and use the toothbrush to gently scrub away the paint. Rinse the toothbrush frequently to clear away paint residue and prevent re-applying it to the model. Continue scrubbing until all the paint has been removed. If you are working with small pieces, be careful as the solution may dissolve the super glue, causing them to fall apart. Be sure to keep these pieces organized so that you can glue them back together once the paint has been stripped.
Using a toothbrush to scrub is a gentle and effective method for removing paint from plastic models. This technique allows you to target specific areas and ensure a thorough paint removal. By taking your time and working carefully, you can achieve a clean and fresh surface ready for a new coat of paint.

Avoid acetone
When stripping paint from plastic models, it is important to avoid using acetone. While acetone is an effective paint remover for metal surfaces, it can be too harsh for plastic, causing the material to soften, weaken, and lose fine details.
Acetone is a common ingredient in nail polish remover and can be purchased at hardware and paint stores. However, when used on plastic, it can cause undesirable results. One user reported that leaving their plastic models to soak in Pinesol, which contains acetone, ruined their miniatures. The acetone softened the plastic and weakened the structure, making the models floppy and destroying the intricate details.
Instead of acetone, consider using 99.9% pure isopropyl alcohol, which is an excellent and inexpensive solvent for removing paint from plastic models. It provides a good base for repainting, is a strong cleaner, and won't damage the plastic. Additionally, isopropyl alcohol is safer for your skin than acetone, which can be toxic and harmful if inhaled.
If you are looking to remove paint from metal models, acetone can be a good option. It is an effective paint remover and can also be used to strip oil, contaminants, and superglue residue from metal surfaces. However, always exercise caution when using acetone, and ensure proper ventilation during the stripping process.
In summary, while acetone is a powerful paint remover, it is not suitable for plastic models due to its harsh effects on the material. Instead, opt for a gentler solvent like isopropyl alcohol to effectively strip paint from plastic miniatures without causing damage.

Soak and scrub
To begin the process, gather the necessary supplies, including gloves, containers, rags, and towels. It is also important to ensure proper ventilation in your workspace.
Once you have the necessary supplies, you can start by filling a container with a suitable paint stripper. Some options include methylated spirits, brake fluid, or a dedicated product like Super Clean (Castrol Super Clean) or Easy Lift Off. Always read the instructions and take the necessary safety precautions when using any chemical.
Next, submerge the plastic model in the paint stripper. The amount of time needed for this step will vary depending on the product used and the thickness of the paint. Some paint strippers may only need a few hours, while others may require several days. It is important to follow the instructions on the product label and test it on a small area first if possible.
After the model has soaked for the recommended amount of time, remove it from the paint stripper and begin scrubbing. Use a soft-bristled brush, such as a toothbrush, to gently scrub the paint away. Rinse the brush frequently to clear any colour residue. Continue scrubbing until all the paint has been removed. For stubborn areas, you may need to repeat the soaking and scrubbing process.
Finally, once all the paint has been removed, rinse the model with clean water and allow it to dry completely before proceeding with any further steps, such as repainting.
