It is essential to properly clean up the surface of the wood after it has been stripped using harsh chemicals. There shouldn’t be any residue left over once the job has been done. This article will offer seven different methods to help you treat your lumber properly so that it lasts longer and stays looking the best it can.

Different Ways to Properly Clean Wood After Stripping Paint

1. Using Vinegar and Water

We’ll start with simple materials you can easily find in the kitchen and won’t have to especially go to the store to purchase and spend money on. Vinegar is a strong liquid with acidic properties that can fight and get rid of any harsh chemical left on the wood due to the use of stripping agents. 

To use this method, you will have to mix equal portions of vinegar and water, then apply the mixture to the desired area using a cloth soaked in it. Rub it using gentle circular motions on the wood. Once you are sure that it is properly cleaned, wash off the vinegar and water combination. Using a damp cloth soaked with clean water, continue to rinse and wipe the surface until you cannot smell the vinegar mixture on it anymore.

2. Using Mineral Spirits and Steel Wool

If the stripping agent used for the paint contains solvents, it is recommended to opt for this method rather than the one mentioned above. Choosing to clean up with mineral spirits is a better option as many stripping products contain wax, which will become quite prominent, ruining the look of the wooden surface. Mineral spirits are quite capable of handling that issue and will also help future protective coatings last long. 

For application, simply pour some mineral spirit on the previously treated area, then using a ball of steel wool, rub the liquid over the surface using a little bit of force, moving it in the direction of the grain. After that, wipe off and clean the surface using water and a rag until satisfied. 

3. Using Lacquer Thinner

You should only use this method if you plan to work in a well-ventilated area and wear protective equipment. Lacquer thinner fumes are toxic, so you need to be wise and careful when using them. 

To apply, wet a rag with a bit of lacquer and dap it on the wood, covering all the surface that was treated by the stripping agent. Do not pour it directly or leave it on for too long. Such carelessness can damage and stain your wood. Clean up the lacquer thinner after a few seconds of the application, using a rag soaked with a mixture of warm soapy water.

4. Using Acetone

Another method that will require you to be in a well-ventilated area. You may either purchase acetone from the store or use nail polish remover as they contain acetone. Acetone will be able to quickly dissolve and fight any residue left by the paint and stripping agent. 

To use it for cleaning up, pour some acetone or nail polish remover on a scrubbing sponge and gently rub the wooden surface in circular motions. Once all the area is covered, clean up with a damp cloth. Then use a cloth with a bit of rubbing alcohol poured on it and wipe the wood to neutralize the effect of the acetone. Finally, go ahead with a damp cloth soaked with water, rinse and wipe until you’re sure that there is no residue left of any chemical.

5. Using Sandpaper

This method will demand that you be quite careful, or else you’ll end up scratching the wooden surface or even sanding it too much.

For this method to work, you’ll have to start by using a sanding block on the flat surfaces and foam on the curves. Then use medium grit sandpaper, following along the direction of the wood grain to sand any remnants and reside left. Finish off by using very fine-grit sandpaper to smooth out the surface. Clean up the mess with a damp cloth soaked with water.

6. Using Scrapers

Do not use a metallic putty knife or a trowel on a delicate surface such as wood; instead, use a putty knife made of plastic to do the job, or else you might accidentally gouge or scar the wood. Also, make sure you scrape along the wood grain, not against it. 

To scrape the residue off the wood, place the tip of the scraper at a 30 or 45-degree angle and gently push forward. Once satisfied with the results, clean any dust and debris on the surface using a damp rag and water, rinse and wipe until the area doesn’t have any dirt left.

7. Using Electric Drill Attachments

The last method! Again you have to be cautious of how your treatment method is affecting the wood’s surface. You do not want to sand off too much, so be careful. Now you may choose between using a wire brush attachment or a rotary sanding attachment for your electric drill; either would. Follow the instructions provided with the tool and later follow up with a damp cloth to clean up any mess. Lastly, remember to wear your protective gear during the process.

FAQ

Do I have to use mineral spirits after stripping?

Well, we can’t force your hand, but we do highly suggest that you do use it. As mentioned above, mineral spirits are quite capable of dealing with the stubborn wax or paint residue left after the paint stripping process. They will also help with smoothing out the future protective coating’s application and longevity. So, if you’re looking to achieve the best results possible, do not skip this process.

Do I have to sand after stripping paint from wood?

Oftentimes, some stubborn paint residue may remain glued to the wooden surface even after the chemical stripping process. In that event, you can easily use sandpaper to quickly get rid of that. You may generally use a palm sander; however, if you are having trouble with some awkward nooks and crannies, then approach those areas using a sanding block or a small piece or strip of sandpaper.

You’ll definitely have to follow up with sandpaper if the stripping method you used was to scrape off the paint using a scraper. In that case, start with an 80 – 120 grit sandpaper, then finish with a 150 – 200 grit sandpaper to smooth out everything down to perfection. 

How long to let the wood dry after stripping?

The answer depends on the type of wood and the stripping method. The hours needed to let it dry can range from 6 to 48. If the wood piece is soft and was previously soaked for several hours, then let it dry for a minimum number of 24 hours, preferably 48. 

Conclusion

I hope you have found a method to clean wood after stripping paint that you’re happy to try out. Remember always to keep safety precautions in mind when you work and enjoy yourself. 

Good luck with your project!
