How to Remove Paint From Plastic
When trying to strip paint from plastic, using a solvent may just damage the item you want to clean. The easiest and safest method to try first is simple, use a rag and some soapy water. Rub the area until the paint comes off and wash clean with a wet cloth. You can also soak plastic items if possible. This is most effective when done immediately and the paint has not dried yet. However, if the paint remains, you can move on to something else. Below are more methods on how to remove paint from plastic.
Scraping the Paint
Another easy method to help you strip paint from plastic is by gently scraping it off using a paint scraper. This method works best on smooth plastic, but whatever the case, be careful to not be too aggressive or you could damage the surface. Instead of a paint scraper, you could also try a blade, screwdriver, or putty knife. Make sure the scraper is at an angle to scrape the paint.
If the paint remains, consider wiping the area with a little warm soapy water, or a little rubbing alcohol, and then try scraping again.
As mentioned, some rubbing alcohol can also help. In this case, apply some of the rubbing alcohol to the paint only and then cover it with some plastic wrap. Wait for 30 minutes before taking the plastic wrap away, then wipe the paint off. This procedure might have to be done two or three times to make sure all the paint is gone. When wiping away the paint, use a cloth as a brush or other abrasive material that can damage the plastic surface. Also, it is a good idea to test out a small unobtrusive area first to see if the rubbing alcohol has any negative effect on the plastic. You also might consider wearing a mask and using some gloves for protection.
Another method for how to remove spray paint from plastic with household items is vegetable oil. Everybody has this in their homes, and it is safe and easy to use for removing paint from plastic. Place a clean cloth into the vegetable oil and rub where the paint has spilled. Here you can apply with a lot more energy until you can see the paint coming off.
How to remove spray paint from plastic with household items? We all most likely have vinegar in the kitchen, so why not use it for removing paint from plastic. However, there are certain things you must take into account, including the type of paint on the plastic surface. Vinegar will remove latex paint most effectively. All you have to do is heat some distilled vinegar in the microwave on high. Leave it in for one minute and it should then be quite warm but not too hot. Dip a sponge into the warm vinegar and rub the area where the paint is on the plastic surface.
Acetone and Solvents
You might need something stronger than vegetable oil when it comes to how to remove enamel paint from plastic, which is where acetone comes in. You can use nail polish, however, if the plastic is colored, a regular acetone-based product will work better. Apply directly to the paint, wait five minutes, and then wipe off with a cloth.
Any solvent gives off toxic fumes, so working in a well-ventilated area is advisable.
You can also consider denatured alcohol, which is stronger, however, you must be careful when using it. Dip a rag into the alcohol and apply only a small amount directly to the paint. Wait five minutes to make sure it is not affecting the paint. Only apply once as the plastic surface will be damaged if too much is used. If you notice the paint is dissolving, you can then scrape the paint off. Once the paint has been removed, there might be a few spots left. Simply wipe the surface with a cloth dipped in some warm soapy water and then leave the surface to dry thoroughly. This method is best used on harder plastics like a bucket and only works to take off latex paint.
You can also use ammonia, which works more on acrylic and latex paints. Mineral spirits will work better on oil-based paints. Solvents should always be tested out first in an unobtrusive area. The different plastic will react differently, so take a Q-tip and place a drop on the plastic surface, and wait to see what happens. If you do not notice any difference, it should be okay to use the solvents.
