Removing oil-based paint from car interior plastic can be challenging as oil-based paint is designed to adhere strongly to surfaces. Before starting, it is important to identify the type of plastic and paint to determine the safest solvent to use. While vegetable oil is a safe option, it may not be effective for hard plastic surfaces with dried paint. In such cases, stronger solvents like acetone, nail polish remover, mineral spirits, or paint thinner may be required. Working in a well-ventilated area and using personal protective equipment are crucial due to the toxic fumes released by paint removers. Testing the chosen solvent on a small, inconspicuous area first helps ensure that it will not damage the plastic. Once the appropriate solvent is selected and safety precautions are in place, the process of removing the paint can begin, followed by neutralization if needed, as per the manufacturer's instructions.

Using nail polish remover
Removing oil-based paint from car interior plastic can be done in several ways, one of which is by using nail polish remover. This method is effective in removing spray paint from cars.
Before attempting to remove the paint, it is important to understand the difference between dyed and painted plastics. Faded dyed plastic can be painted over, but painted plastic needs to have the paint removed first. As plastic is less durable than metal, the safest way to remove paint is by using a chemical stripper.
Nail polish remover is a type of acetone, which is formulated to remove the enamel layer from fingernails, similar to what you want to achieve with the car's finish. To use this method, pour the nail polish remover onto a cloth, preferably a terrycloth or microfiber towel, to avoid scratching the clear coat or paint on the car. Keep the cloth wet at all times, and if it starts to dry out, add more nail polish remover. Wear gloves to protect your hands from the acetone and paint transfer, and rub the cloth gently in small, circular motions to remove the paint.
It is important to note that this method should be tested on a small, inconspicuous area first to ensure it does not damage the plastic. Additionally, the longer the paint bakes in the sun, the harder it will be to remove, so it is best to remove the paint as soon as possible.
Another product that can be used to remove oil-based paint from car interior plastic is amyl acetate, which is effective in removing nail polish from plastic.

Soaking in vegetable oil
Removing oil-based paint from car interior plastic can be challenging, but with the right approach and some elbow grease, it can be done. Here's a detailed guide on how to tackle this task using vegetable oil:
Prepare the Area and Protect Yourself:
Before starting, ensure you are working in a well-ventilated area, such as a garage with the door open or an outdoor space. Paint removers release toxic fumes, so wear a respirator and rubber gloves to protect yourself. Lay out a drop cloth on a flat surface to catch any drips or excess paint. If you are removing a plastic part from your car, place it on plastic sheeting.
Soak in Vegetable Oil:
Vegetable oil is an effective and safe option to loosen the paint from the plastic surface without causing damage. It is particularly useful for items like plastic furniture and car interior plastic. Pour vegetable oil onto a paper towel or cloth and generously apply it to the painted area. If the plastic piece is small enough, you can also soak it in a container filled with vegetable oil for a few minutes up to an hour. This will help soften the paint and make it easier to remove.
Scrape Away the Paint:
Once the paint has softened, use a plastic scraper or putty knife to gently remove the loosened paint. Be careful not to apply too much pressure, as you don't want to scratch or damage the plastic. Work in the direction of the grain to avoid leaving marks. This process may require some muscle power, especially if the paint is particularly stubborn.
Clean and Neutralize:
After scraping away most of the paint, use a clean cloth soaked in paint thinner, turpentine, or mineral spirits to wipe down the area and remove any remaining paint residue. You can also use acetone or denatured alcohol, but avoid these if you are working near water, as they can be harmful. Continue blotting and re-moistening the cloth until all the paint is removed. Finally, wash the plastic with warm water and soap to neutralize the surface and remove any remaining chemicals.
Additional Tips:
- Before using any solvent, test it on a small, inconspicuous area of the plastic to ensure it won't cause damage or discolouration.
- Keep in mind that vegetable oil may not completely remove the paint, and you may need to repeat the process or use additional tools like sandpaper for stubborn areas.
- Always follow the manufacturer's instructions for any products you use, including safety precautions and recommended application times.

Soaking in isopropyl alcohol
Isopropyl alcohol, also known as isopropanol or IPA, is a versatile and reliable product that can be used to remove oil-based paint from car interior plastic. It is a cheap and easy way to remove greasy or oily substances that tend to cling to glass or paint.
Before using isopropyl alcohol to remove oil-based paint from car interior plastic, it is important to test it on a small, inconspicuous area to ensure it won't damage the plastic. It should not be used on certain delicate materials such as vinyl, leather, or other surfaces that may be present in car interiors, as it may cause drying, cracking, or discoloration.
To use isopropyl alcohol for paint removal, start by removing the plastic car part that you intend to strip and repaint. Lay the part out on plastic sheeting and scuff the paint with fine sandpaper to make it easier to remove. Then, wearing protective gloves, apply the isopropyl alcohol to a clean cloth and wipe down the painted part thoroughly. The alcohol will start to break down the oil-based paint, causing it to wrinkle or bubble. Once the paint starts to lift, use a plastic scraper to gently remove the paint from the car part.
It is important to note that isopropyl alcohol should always be diluted before use. Undiluted isopropyl alcohol can eat away at the clear coat of your car over time. Additionally, it should not be used after every wash, but rather on an as-needed basis.

Using a chemical paint stripper
To remove oil-based paint from car interior plastic, you will need to use a chemical paint stripper. This is because plastic does not have the same durability as metal, and the only safe way to remove paint from plastic is by using a chemical stripper.
Before using any chemical paint stripper, it is important to test it on an inconspicuous area to ensure it will not damage the plastic. You should also ensure you are working in a well-ventilated area, as chemical strippers release toxic fumes. Lay out a drop cloth on a flat surface to protect the area from any potential chemical drips or excess.
Wear protective clothing, including long sleeves, long pants, socks, and shoes or boots. Additionally, wear thick rubber gloves, eye protection, and a respirator.
Start by pouring the chemical stripper into a metal coffee can or a similar container. Use an acid-resistant brush to dip into the stripper and then paint it onto the plastic car parts. Follow the manufacturer's instructions as each type of chemical stripper has slightly different procedures.
Once the paint starts wrinkling or bubbling, use a plastic scraper to remove the paint from the car part. You might need to apply a second or third coat of the stripper, depending on the number of coats on the original part. Once most of the paint is gone, apply a final lighter coat of the stripper and rub it with a scouring pad to remove any remaining paint.
If the instructions require a neutralizer for the stripper, you can do that at the end. Finally, wash your skin with lots of soap to get any chemicals off.

Using acetone
To remove oil-based paint from car interior plastic, you can use acetone, a solvent that works well on oil-based paints. However, it is important to note that acetone is strong enough to damage, dissolve, or melt plastic, so caution is advised. It is recommended to start with low-impact solvents and then move on to stronger ones if needed.
Before using acetone, identify the type of plastic and paint to determine the safest approach. Water-based paints like latex or acrylic tend to have a duller sheen and fade over time, whereas oil-based paints are glossier and yellow as they age. ABS plastic, for example, is rigid and comes in various colours, commonly used for car and motorcycle parts.
If you intend to strip and repaint plastic car parts, it is advisable to remove them from the car first. Lay the parts on plastic sheeting and scuff the paint with sandpaper to facilitate easier removal. Ensure you wear protective clothing, including long sleeves, pants, socks, and closed shoes. Additionally, use a dust mask and respirator to prevent the inhalation of paint particles and toxic fumes.
Now, for the process of using acetone:
- Put on protective gloves and safety glasses to keep the acetone off your skin and out of your eyes.
- Pour the acetone into a metal or glass container.
- Dip a clean rag into the acetone.
- Rub the paint-stained plastic with the acetone-soaked rag.
- The paint will start to dissolve within a few minutes. Switch to clean sections of the rag as the paint transfers to the fabric.
- Finally, wash the area with soap and water to remove any acetone residue.
It is important to note that acetone should not be stored in a plastic container as it can melt plastic over time. Additionally, always test any solvent in an inconspicuous area first to ensure it won't damage the plastic surface.
