How to Remove Paint from Plastic

It is a tricky task to remove paint from plastic. It may be easy to remove paint from metal, wood or ceramic, but plastic requires more careful attention. There are solvents out there that will easily damage or even melt plastic, so make sure to use plastic-safe paint removal products or alternatives. Here are some paint-removing steps to follow in order to prevent damaging the plastic product even more

Step 1 – Use a Paint Scraper

Using a scraper may remove the paint from a plastic product but not all the time. When scraping paint off of a plastic product, make sure not to apply too much pressure to avoid scraping the plastic as well. Use a plastic putty knife and a razor blade. Be very careful when using the blade. Use it only when dealing with thick dried-up paint

Step 2 – Try Vegetable Oil

Vegetable oil can be used to loosen up the paint on a plastic surface. Place a small amount on a rag and rub the oil onto the affected surface until the paint gets a bit loose. If the paint does not come off after several attempts, it is best to try other stronger solvents. You’ll then need to use detergent to remove the oil from the plastic.

Step 3 – Use Nail Polish Remover

Place a sufficient amount of nail polish remover on the paint and rub it with a paper towel. If the paint does not come off easily, leave the solvent in place for about 5 to 10 minutes before rubbing again.

Step 4 – Apply Denatured Alcohol

Paint thinner will probably have no effect on paint, unless the paint is still wet. But when stronger paints do not succumb to vegetable oil or nail polish remover, denatured alcohol is effective at removing latex paint. It will not affect oil base paint. Try a small area with the denatured alcohol to make sure it will not damage the plastic, and if it is latex paint on the plastic, the denatured alcohol should be helpful to remove it. Denatured alcohol poses more health risks than the other solvents so it needs more preparation.

Before applying the solvent onto the paint, make sure to use rubber gloves to protect your hands from direct contact with the chemical. Wear a respirator and work in a well ventilated space as much as possible. If not, use an electric fan to induce the movement of air within the working space.

Place a liberal amount of the solvent on the paint and wait for a few minutes to allow the solvent to dissolve the paint. When the paint starts to wrinkle, scrape it off using a plastic putty knife. Use a rag to scrub the area until the paint is removed.

Step 5 – Scrub the Area

After removing a significant amount of the paint on the surface of the plastic, pour warm water on a sponge and add a detergent. Use the sponge to scrub the affected area and remove the alcohol or any other chemical as well as any residue of paint left.
