Whether you want to get an existing coat of spray paint off your wooden furniture, or just get rid of accidentally applied spray paint, the process might sound quite daunting.
However, removing spray paint from wood isn’t as hard as you think. You can use many different methods, and I’ll cover many of them in this article. So strap on your cleaning gear and let’s get started.

The Simple Solution
Many DIY’ers think that only chemicals and scrapers can remove spray paint from wood, but you can damage the wood in most cases, especially if you are new to this.
To start with, try some soap, water, and a rag. Scrub with as much pressure as you can muster. This will only work for newly painted areas. If the paint has had a lot of time to dry, this method probably won’t be effective.
Paint Strippers
If you are trying to remove spray paint from a horizontal wooden surface, it would be best to use a liquid stripper, like this New Generation Stripper.
When removing spray paint from a vertical wooden surface, you should opt for a gel or paste, like the Max Strip Paint & Varnish Stripper.
Using a liquid stripper on a vertical surface could result in the stripper dripping to the floor, which could cause quite a bit of damage. These pastes and gels are easy to apply using a paintbrush or roller.
Once applied, leave the paint stripper to do its magic for about an hour. When you start to see the paint bubble, you know that it’s ready to be removed.
If the wood you are trying to strip is very delicate, it would be best to use a plastic scraper like this to scrape the softened spray paint. Although this tool is very effective, I still prefer a metal scraper and try to be as gentle as possible.
Glide the scraper under the paint, using long, smooth movements, and always ensure you are gliding in the same direction. Try to remove the majority of the paint with the scraper.
For any remaining paint, soak some medium-grade steel wool in the stripper and scour the surface. This should remove all the paint, especially in hard-to-reach areas.
Unfortunately, since wood is porous and not at all level (even though it might be to the naked eye), it may still need a bit of sanding afterwards.
It is important to remember to wear protective gloves, masks, and goggles throughout this process to avoid accidents.
Acetone
Using a clean rag, douse it in acetone and spread it over the area using a generous amount. Let it seep into the paint for several minutes.
Take a clean rag and dampen it with more acetone and start to scrub the spray paint away. Once your rag is full of paint, use a new one. Continue doing this until you reach the bare wood. When done, rinse the area with clean water to remove any residue and acetone that are left behind.
Removing Spray Paint from Wood without Damaging the Finish
If you attempt to remove spray paint from wood, it can be hard not to damage the finish. Using harsh chemicals can cause the paint to seep further into the wood, and applying too much pressure when scraping or sanding can damage the finish.
Mineral spirits are the best method you can use in this situation. Olive oil can be used to coat the surface and will prevent any scratching. Just pour a few drops onto a dry cloth and spread it over the surface. Take a clean, dry cloth and set it over the area of spray paint you would like to remove.
A putty knife is a great tool you can use to scrape the paint away, using the rag as a protective layer between the surface and the putty knife. Use a clean rag to wipe away any olive oil residue.
Now it’s time to apply some mineral spirits. Dampen a small area of a clean rag with the mineral spirits and wipe away any excess paint. It’s as easy as that. Ensure to clean up any left-over mineral spirits with a dry cloth.
For small amounts of spray paint (such as a mild mist of spray paint), it might be a lot easier to remove them. Check out this video:
Get Spray Paint Off Wood Naturally
If you want to avoid using chemicals that can be toxic to your body, there are more natural ways of removing spray paint from wood.
Heat Guns
Using a heat gun to remove spray paint can be risky, and I would not recommend this method to beginners.
If misused, you could damage the wood or even set it alight. Even for the more seasoned users, I would recommend you practice before using it on your project.
This method works by heating the spray paint until it starts bubbling and then using a paint scraper to remove it.
Remove Spray Paint by Sanding
This is one of the most straightforward techniques you can learn. You won’t need much, and it is very effective. I would personally use a hand sander or sanding tool instead of just using a piece of sandpaper and your hand.
You will need heavy-grit sandpaper, and using a lot of pressure, sand the paint off the surface of the wood, ensuring to always sand with the grain and not against it. This will be messy, so I would recommend only sanding outside and wearing a dust-filtering mask.
Should this be your preferred method, ensure you are not sanding lead-based paint as it can spread fine molecules of lead that are harmful and can cause severe problems to your lungs.
Vinegar
This technique is not as effective as the others, but it will soften the paint and allow you to scrape it off.
It’s as simple as heating the vinegar on the stove or in the microwave and apply it to the surface with a paintbrush. Let it seep into the paint for a few minutes, and use a paint scraper to scrape off the softened paint.
For Extensive Jobs, Use a Pressure Washer
Pressure washers work well for larger surfaces like decks or fences. Ensure that your pressure washer is at least 2,500 PSI.
Of course, you can’t use a pressure washer indoor (unless you want to spill a lot of water around), so you’ll need to take your indoor furniture outside, preferably out on your yard before you can start with this process.
I personally only had success with this method for removing spray paint that didn’t get much time to dry. It was a very time saving process compared to other methods. For completely dried up spray paint, you’ll rarely find any success using a power washer.
Natural Paint Strippers
Citrus-based or soy gel paint removers like the Safe ‘n Easy Citrus Paint & Varnish Remover Gel are similar to paint strippers but are not made from toxic chemicals. They work well and are better for the environment.
As usual, you need to give them some time (around 30 minutes to an hour) for the wood to soak up the paint remover. Afterwards, clean and rinse off as usual as you’d in case of regular chemical-based paint strippers.
How to Remove Water-Based Spray Paint
This technique requires you to scrape off the spray paint using a paint scraper or butter knife. Although pressure is needed, try not to use too much force to preserve the finish of the wood underneath.
You can also use soap to make the cleaning more effective.
You can use a nylon scrubbing brush to scrub the remaining paint away. If needed, apply more soap and continue scrubbing until all the paint has been removed.
Once you are satisfied, use a clean cloth to dry the area thoroughly.
How to Remove Oil-Based Spray Paint
Oil based spray paint is harder to get off wood than its water based counterpart. For this, you’ll have more success using rubbing alcohol instead of plain soap or liquid detergent.
Without going into the technicalities, rubbing alcohol can penetrate the oil-based paint much more effectively, thus making it better suited for this job.
Conclusion
It is possible to remove spray paint from wooden surfaces safely without damaging them. There are a variety of methods you can use that are effective.
Although all these methods work, especially when elbow grease is applied, I find that the natural citrus-based paint strippers to be the most effective.
Always ensure to wear protective clothing like gloves, goggles, and a mask as a safety precaution. Most toxic chemicals used for this purpose can be harmful to your body.
It is now up to you to decide which method will work best for you. Once you have a technique in mind, follow these easy instructions and get that DIY project underway!
