Removing Krylon paint from plastic models can be a tricky process. While some suggest using an oven cleaner, others advise against it and recommend a paint remover specifically designed for plastic models. It's important not to use an aircraft stripper as it can damage the plastic. An alternative method is to use a lacquer thinner by applying it to a soft cloth and wiping it over the painted area. After allowing it to soak for 20 minutes, the paint can be scrubbed away with a scouring pad. For stubborn paint, a strong paint stripper like ELO (Easy Lift Off) can be used, which causes the paint to bubble and be cleaned off with a toothbrush.

Paint remover
Removing paint from plastic models is an essential step when repainting to ensure a beautiful, fresh effect. There are several paint removal methods and products available, each with its own advantages and disadvantages.
One popular method is to use a chemical paint remover. These products are designed to dissolve paint quickly without damaging the underlying plastic. For example, TAMIYA 87183 Model Paints & Finishes Paint Remover is a liquid remover that can be applied with a cloth or cotton swab and is safe to use on various plastics, including polycarbonate. It is capable of removing acrylic, enamel, and lacquer-based paints. When using chemical paint removers, it is important to wear gloves and work in a well-ventilated area to protect your safety.
Another option is to use a natural solvent like isopropyl alcohol or methylated spirits. These solvents are inexpensive and easily accessible, and they can be used to soak the painted model before scrubbing with a toothbrush. This method may require multiple applications for thorough paint removal. When using isopropyl alcohol, it is recommended to use 99.9% pure isopropyl alcohol for the best results.
Some sources suggest using oven cleaner to remove paint from plastic models. However, it is important to note that oven cleaner may not be as effective as other methods and could require additional sanding to smooth the plastic before repainting. Additionally, it is crucial to avoid using an aircraft stripper, as it can damage the plastic.
When removing paint, it is important to consider the type of paint on the model. For example, removing enamel paint may be more challenging than removing acrylic paint due to the presence of stubborn oils in enamels. It is also essential to prepare the necessary supplies, such as containers, rags, and towels, to ensure a clean and efficient process.
Lastly, it is worth mentioning that some paint removal products can also dissolve super glue, which can be useful for removing parts from bases. However, this can also cause issues if the model has small parts held together with super glue.

Oven cleaner
Spray or apply the oven cleaner generously onto the painted areas of the plastic model. Allow it to sit for a few minutes to give the chemicals time to act on the paint. Use a soft brush or cotton swab to gently scrub the paint. The oven cleaner should have weakened the bond between the paint and the plastic, making it easier to remove. Rinse the model with warm water to remove any residual oven cleaner and paint residue.
If necessary, repeat the process for any stubborn areas or layers of paint that remain. It is important to note that oven cleaner may not always provide a perfect finish, and there is a risk of damaging the plastic if not done carefully. Always test on a small, inconspicuous area first to ensure the plastic can withstand the chemicals.
Additionally, consider using alternative methods or products specifically designed for paint removal on plastic models. These products are typically gentler and carry a lower risk of damaging the plastic. However, they may require more time and effort to completely remove the paint. As always, refer to the manufacturer's instructions and recommendations for the specific oven cleaner or alternative product you choose to use.

Isopropyl alcohol
Removing paint from plastic models can be tricky as some methods may be too abrasive and cause damage. Krylon paint is one of the largest suppliers of aerosol paints and is used by many artists, painters, and customers. While commercially available paint strippers can be used on metal surfaces, they are often too harsh for plastic.
Another method is to use a lacquer thinner. Saturate a soft cloth with the thinner and wipe it over the painted area. Allow the thinner to soak into the paint for 20 minutes, then scrub away the paint using a scouring pad in a firm, circular motion.
Oven cleaner can also be used to remove Krylon paint from plastic. Spray a small amount of oven cleaner into a ziplock bag, place the model inside, and spray more cleaner to cover it. Leave it to sit overnight, then wash the model with dish soap and rinse it in distilled water.
When removing paint from plastic, it is important to avoid using harsh chemicals like aircraft stripper, as these can damage the plastic. It is also important to prepare your workspace by laying down protective materials and wearing a painting mask. Additionally, always refer to the instructions on the spray can for safety and application guidance.

Sanding
Before initiating the sanding process, it is crucial to prepare the plastic surface adequately. Start by cleaning the plastic model with a damp cloth or sponge and a mild detergent or soapy water. This step ensures that any dirt, grime, or residue is removed, providing a clean base for the sanding to be more effective.
Once the surface is thoroughly cleaned and dried, you can begin the sanding process. It is advisable to start with a finer-grit sandpaper, such as 220-grit or higher, to gently abrade the painted area. Always sand in the same direction, following the grain or pattern of the plastic, if applicable. Avoid using too much pressure, as this can create indentations or scratches on the plastic.
For more intricate details or hard-to-reach areas on the plastic model, you may need to use smaller pieces of sandpaper or a sanding block with a contour profile to conform to the shape of the model. Take your time and work in small sections, regularly checking your progress to avoid over-sanding any particular area.
After sanding, it is essential to remove any residual dust or debris from the surface. You can use a soft brush or compressed air to gently dislodge any remaining particles. Finally, you can choose to apply a primer or paint directly over the sanded area, depending on the desired finish and the condition of the plastic model.

Paint stripper
There are several types of paint strippers available, including solvent-based, heat guns, sanding, scraping, and chemical strippers. Solvent-based strippers use chemicals to dissolve the paint and are effective for removing multiple layers. However, they can be harmful to the skin and dangerous if inhaled. Heat guns use high heat to soften and loosen the paint, but they must be used with caution as they can also damage the underlying surface if not carefully applied. Similarly, sanding can be effective but may not work well on thick layers of paint and can be time-consuming. Scraping with a flat tool, such as a putty knife, is best for thin layers of paint.
Chemical strippers are specifically designed to remove paint and are available in liquid or gel form. One such product is the GSW Paint Remover, which has been tested on both metal and plastic miniatures. While it has been praised for its effectiveness and lack of strong chemical smells, some users have noted that it loses its effectiveness over time. Another option is the Motsenbockers Lift Off, a citrus-based paint and varnish stripper that is safe for plastic as long as it is not left on the surface for too long. Simple Green is another non-toxic, biodegradable option that is effective but requires a longer soaking time, typically overnight.
When using any paint stripper, it is important to proceed with caution to avoid damaging the plastic model. Some products can easily melt the plastic, so always test on a small area first and follow the instructions carefully. Additionally, ensure proper ventilation when working with chemicals and wear protective gear, such as a respirator mask, to avoid inhaling toxic fumes.
