Use isopropyl alcohol and a toothbrush to strip the paint
To remove paint from a plastic model, one of the best methods is to use 99.9% pure isopropyl alcohol and a toothbrush. This method is inexpensive, safe, and effective.
First, ensure you have a well-ventilated workspace and cover your work surface with old towels or rags to protect it from spills or accidents. Prepare at least three containers: one for stripping, one for washing your brushes, and one for organizing your clean brushes. Fill the first container with enough isopropyl alcohol to soak the model, the second with water, and leave the third empty. Put on a pair of gloves to protect your skin from the chemicals.
Next, submerge the model in the container of isopropyl alcohol. Cover the container and let it soak for around 20 minutes or longer for deeper paint penetration. If the model has multiple coats of paint or hard finishes, you may need to soak it for longer or submerge it multiple times.
Once the paint has softened, remove the model from the alcohol and use a toothbrush to strip the paint away. Rinse the brush frequently to clear away colour residue, and switch between clean brushes as needed. Continue scrubbing until all the paint has been removed.
Finally, rinse the model with warm water and allow it to dry completely before applying a fresh coat of paint.

Soak the model in warm water to loosen the paint
Soaking your plastic model in warm water is an effective way to loosen the paint and prepare it for removal. This method is gentle on the plastic, ensuring that the material and fine details are not damaged or softened in the process.
To begin, boil a kettle of water and set up your workspace. Place a towel down on your work surface to protect it from spills and have some paper towels or kitchen paper handy to address any accidents quickly. You will also need a bowl of cold water to help handle the model once it is removed from the warm water.
Next, fill a bowl with the hot water from the kettle. Be careful not to burn yourself and avoid splashing. If your model is a small piece, you can dip it into the water, holding onto the bottom to avoid fully submerging it. For larger pieces, fully submerge the model in the hot water. Leave the model in the water for 30 seconds to a minute. The thicker the piece, the longer it will take for the heat to penetrate to the core.
Once the paint has been loosened by the warm water, carefully remove the model from the bowl. Use a grabbing instrument, such as a pair of tongs or a clean fork, to lift it out, being cautious not to touch the hot water. Immediately place the model in the bowl of cold water to stop the heating process and prevent any potential warping of the plastic.
At this point, you can begin to gently scrub the model with a toothbrush to remove the loosened paint. Rinse the model and brush frequently during this process to wash away the paint residue. Repeat as necessary until all the paint has been removed.
By soaking your plastic model in warm water, you can effectively loosen the paint and achieve a clean surface ready for a fresh coat of paint.

Use acetone-based nail polish remover to strip paint from metal models

Acetone is the magic ingredient in nail polish remover that strips paint off metal miniatures in seconds. You can buy acetone at any hardware or paint store. However, be careful with the fumes and avoid getting it on your skin.
Note that acetone should not be used on plastic models as it will dissolve the plastic.

Cover your workspace with rags and towels to prevent damage from spills
Before you begin the process of removing paint from a plastic model, it is important to prepare your workspace. This step is crucial to ensure a safe and efficient paint removal process. By taking the time to cover your workspace with rags and towels, you can effectively prevent any damage caused by spills or accidents. Here's a step-by-step guide to help you get started:
Firstly, choose an appropriate work area that provides enough space for your project. It is recommended to select a well-ventilated area to ensure proper airflow during the paint removal process. Cover the entire surface of your workspace with old towels or rags. This creates a protective layer that will catch any spills or drips, protecting your work surface from damage. Make sure the towels or rags are large enough to cover the entire area, with some overlap to prevent any gaps.
Once you have a covered surface, gather all the necessary supplies within reach. This includes having a separate set of clean rags or paper towels specifically for addressing spills or wiping your hands. Keep a stack of these nearby so that you can quickly absorb any spills or messes during the paint removal process. Additionally, have a small bin or container designated for disposing of used rags and towels. This helps to maintain a tidy workspace and facilitates easy cleanup once your project is complete.
It is also important to consider the type of rags or towels you will use. Old towels or cotton rags are ideal for covering your workspace as they are absorbent and can contain spills effectively. Avoid using thin or delicate fabrics that may not provide sufficient protection. Additionally, ensure that the towels or rags you use are ones that you don't mind getting stained or damaged, as the paint removal process may result in permanent marks.
By following these steps and taking the time to properly cover your workspace, you can effectively prevent damage and create a safe and efficient environment for removing paint from your plastic model. Remember to prioritize ventilation and have all the necessary supplies within reach. With the right preparation, you can ensure a smooth and hassle-free experience.

Use Simple Green to strip paint from plastic or metal models
When it comes to removing paint from plastic or metal models, Simple Green is a popular choice. It is a cleaner that can effectively strip paint from a variety of surfaces, including plastic and metal. Here's a step-by-step guide on how to use Simple Green to remove paint from your models:
Prepare Your Work Area:
Before you begin, ensure you have a well-ventilated work area as the fumes from Simple Green can be strong. Cover your work surface with old towels or rags to catch any spills and have some paper towels handy for quick clean-ups. Wear gloves to protect your skin and keep a steady hold on the models without getting your hands dirty.
Soaking the Models:
Fill a container with Simple Green and fully submerge the models in it. Let them soak for at least three days to a week. Keeping the solution warm during soaking can speed up the process. The paint will start to loosen and come away from the models. Simple Green is safe to use on plastic, but be cautious with metal models as it may weaken super-glue joints.
Scrubbing and Rinsing:
After soaking, remove the models from the solution and use a toothbrush to scrub away the loosened paint. Rinse the brush frequently to clear colour residue. If necessary, submerge the models again for a few hours or overnight if there are multiple coats or stubborn areas. Finally, rinse the models under warm water to remove any remaining residue.
Final Touches:
Use a knife to carefully pick out any remaining bits of paint that may be stuck in crevices. If you're working with metal models, you may need to use an acetone-based nail polish remover for any stubborn paint spots, but be cautious as acetone can be harsh on skin and give off strong fumes. Always test any paint removal method on a small, inconspicuous area of the model first to ensure it doesn't cause damage.
Reusing Simple Green:
Simple Green is reusable! Filter the solution through a coffee filter to remove paint flakes, and you can use it again for your next project. Remember to always follow the manufacturer's instructions and take the necessary safety precautions when working with any chemicals.
