Mineral spirits is used for cleaning and getting rid of stains from surfaces. But, can mineral spirits remove paint?
Mineral spirits can remove paint, stain, and sealers from different surfaces, including metal and concrete. It is a solvent that is made up of petroleum distillates. This makes the compound strong enough to dissolve and remove paint.
Mineral spirits will strip dried paint from surfaces by breaking and dissolving paint particles. Once the particles are dissolved, you can wipe off the coating from the surface. It will also dissolve the polymer and separate the pigments making the coating lose its bond and fall off.
Removing dried paint, stain, or sealant from a surface is hard. That’s because the coating has cured and hardened over time. But, since mineral spirits is made from petroleum distillation and is heavily refined, it removes them easier.
However, mineral spirit is better at removing dried oil-based paints. That’s because it is a mild irritant with active petroleum distillates more suited to dissolving and removing oil paints.
It also removes dried water-based paint, but it’s too strong for it. So, you should try using a weaker solvent, such as rubbing alcohol, first. Water-based paints are dissolved by mineral spirits within minutes by separating the pigments. When the pigments are separated, the coating will lose its bond on the surface and fall off.
However, mineral spirits won’t strip dried spray paint. It can only strip fresh spray paint.

How To Use Mineral Spirits To Remove Paint?
Removing paint or a finish from a surface using mineral spirit is effective, but a task that also requires caution and the right steps.
Here are the tools you need:
- Mineral Spirit
- A Pair Of Work Gloves
- A Face Mask
- A Bucket Of Warm Water
- Clean Rags
- A Scrubbing Brush
- Mild Detergent
- A Paint Scraper (Or A Putty Knife)
1. Clean The Affected Surface
First, clean the affected surface with a rag. Cleaning the surface before helps to get a clearer view of where the paint is. Especially, if you are working on a dusty surface. To clean, wipe the surface with a rag.
2. Scrape The Paint Off
Use a paint scraper to remove some of the coating from the surface. You can also use a towel, metallic putty knife, or any flat object to remove it off the surface. While scraping it off, don’t use a lot of force, or you may ruin the surface by creating dents and holes in it.
Scraping helps reduce the amount of paint on the coating. This also helps to reduce the amount of mineral spirit required. For the record, mineral spirits is expensive.
You shouldn’t remove all the coating from the surface with a scraper, just some parts of it. Vacuum the spot or remove dust with a soft brush when you are done scrapping.
3. Apply Mineral Spirit
You can apply mineral spirits directly to the finish or by using a spray bottle and a rag. If there’s little paint left after scraping, you can douse a rag with it and use the damped rag over the surface. If there’s a lot of paint left after scraping, spray it or pour it directly.
The amount of mineral sprits you must use depends on the surface type. If you are removing paint from a sensitive surface or material like fabric or plywood, mix it with water to dilute the concentration. But you can apply it directly if it’s a tough surface such as concrete.
After applying it, let it sit on the surface for a few minutes.

4. Wipe The Paint Off
After a few minutes, the paint will peel off, even without wiping the surface. This is because the mineral spirits will dissolve the pigments and particles making the coating lose its bond.
Some paint types might liquefy (turn liquid) when exposed to mineral spirits. When the coating starts to fall off, change color, change consistency, or liquefy, it’s time to wipe it off.
Use a clean damp rag to do it. After wiping it off, check if all the coating is gone. If you have leftovers on the surface, apply more mineral spirit and wipe again.
When satisfied with the result, you can move on to the next step.
5. Clean The Surface With Warm Soapy Water
You have to clean the surface with warm soapy water to remove the residue of the mineral spirit. If you don’t, the next coating won’t still well over that surface.
To clean it, mix detergent with warm water and use the mixture to clean the surface.
If you are working on a porous surface, soak a rag in warm soapy water and wipe the surface with the rag. If you are working on a hard surface like concrete, you can wash the surface with soapy water and a scrubbing brush.
