What You Need to Know About Removing Spray Paint from Plastic
Removing spray paints from plastic is very difficult.
Because the rubber is liable to be destroyed or at least discolored due to both the dried paint and the paint thinner, it’s tough to get it cleaned safely.
That’s why patience is one of the most necessary traits when performing this task, because you’ll have to ramp up the strength of the cleaning products you’re using slowly.
This will help prevent any additional damage and allow your plastic products to escape from the paint unscathed.
Proper personal protective equipment, or PPE, is necessary for this, because you'll be working with strong solvents.
Make sure to wear gloves and goggles to protect your hands and eyes from getting irritated by the mineral spirits or paint thinners you may be using.
Hopefully, you can avoid using them, as long as you get to the affected area quickly.
This is a tricky process, and manual effort with a razor blade or putty knife may be more useful and safe in the end than using chemicals.
Just remember to be quick and careful with everything you do if you want to salvage the plastic pieces with which you're working.

Supplies You’ll Need for Removing Spray Paint from Plastic
When you’re trying to clean spray paint, or any other type of paint, from plastic, it can become a messy and tiresome process, especially if you don’t have the proper tools on hand.
Unfortunately, this is not a process of trial and error, because any mistakes will cause the plastic to deteriorate, ruining any progress you’ve made. Here are the most important supplies to have on hand.
- Warm water - Warm water will be useful to rinse off the surface before you try and remove the paint, but it’s also important for the remainder of the steps. If the paint is still wet, you may be able to remove it with warm water. If not, you can use it in conjunction with the soap or to cut the paint remover to make it less likely to damage your plastic.
- Soap - If warm water doesn’t cut it, try using a soapy water mixture to break down the paint on the surface so that you can scrub it off. If this dish soap doesn’t work, at least the surface will be cleaned of any dirt or grime that will impact the removal process.
- Towels - Towels or paper towels are for scrubbing and cleaning up, preventing too much mess and helping to wipe off any paint as it breaks down.
- Paint thinner/remover - Paint thinner or remover is a heavy duty option, but be careful when using it because of the possibility of damaging the plastic. It should be seen as a last resort. The best option is to mix a bit with water to see if you can remove the paint and preserve the plastic, increasing the concentration of thinner as you go along.
- Brush - Depending on how intense the paint is, you may need a brush to help scrub it off as you’re working. A plastic putty knife or paint scraper will also be helpful.
How To Remove Spray Paint from Plastic (5-Step Guide)
- Rinse the Surface with Water
- Try to Scrub the Paint Off with Soapy Water
- Use a Paint Thinner/Water Mixture to Remove the Paint
- Increase the Paint Thinner until the Paint Comes Off
- Wipe Off the Excess Paint and Clean Up
Step 1 - Rinse the Surface with Water
Take the warm water you have and rinse the surface.
Like we said earlier, if you get to it early enough, you may be able to remove wet paint with just warm water. Rinsing is a useful step in paint removal projects because there is always a possibility that there is a bit of wet paint still mixed in with the dried paint.
You should clean this off before you start using a paint remover or dish soap because it can spread the paint to a larger affected area and give yourself more work.
Step 2 - Try to Scrub the Paint Off with Soapy Water
If the paint is still on the plastic, take some soapy water and try to scrub it off.
The brush will come in handy here, allowing you to bear down a bit better and use elbow grease to help remove the paint.
Step 3 - Use a Paint Thinner/Water Mixture to Remove the Paint
Mix a bit of paint thinner in with some clean water.
Don’t go higher than 20% paint thinner or paint remover to start with because it can quickly damage the plastic. Test a small area of the plastic first to make sure that it is safe.
If the affected area is not drastically impacted by the rubbing alcohol or stripper that you've chosen, go ahead and start using the mixture to remove the paint.
Do not leave it on too long, though, because even if it didn’t immediately cause damage to the plastic, prolonged exposure can still harm the material.
Step 4 - Increase the Paint Thinner Until the Paint Comes Off
If you’re still having trouble removing the paint, increase the amount of paint thinner little by little.
It’s important to keep checking small spots in case you’ve overdone it, and you’ll need to wipe it off quickly each time to ensure that it doesn’t damage the plastic.
Step 5 - Wipe Off the Excess Paint and Clean Up
Once you’ve started to make progress, you can begin to wipe off the excess paint and clean off your surface. If you
