Mineral Spirits Vs Paint Thinner

Technically, mineral spirits and paint thinner are almost the same. Mineral spirits can be used as a paint thinner, and many people use the terms mineral spirits and paint thinner interchangeably.

Each type of mineral spirits and/or paint thinner have different combinations of chemicals that achieve the same goal: thinning and/or removing paint.

Mineral Spirits Vs Paint Thinner: What can You Use them For?

Both mineral spirits and paint thinner can be used for the same tasks including:

  • Clean and prep paint surfaces
  • Thinning Oil Based Paints and Primers
  • Cleaning Paint Tools
  • Degreasing
  • Removing Paint Spills

Clean and Paint Prep Surfaces

Mineral spirits and paint thinners are perfect to clean and prep even the toughest surfaces for painting.   

Mineral spirits and paint thinners preserve your wood surfaces better than other types of paint removers such as acetone. We recommend using them to prep your surfaces instead.

Thinning Oil Based Paint and Primers

Best use for paint thinners and mineral spirits is thinning oil based paint and primers for your paint sprayer.  This is the most common use.

Mineral spirits may be hard to come by in your area or even banned. Check out our post on alternatives to mineral spirits and see if you can find something suited for your project.

Cleaning Paint Tools 

Mineral spirits and paint thinners can both be used to clean up your paint tools. 

If you are cleaning a paint sprayer, we recommend using an automotive lacquer thinner.  It is specially made for cleaning spray guns. 

Always run water over your paint tools or through your sprayer afterwards, to remove any film the thinner *might* leave behind. 

Then air dry your stuff once you’re done to avoid rust or residue being left in your sprayer parts.   

Be careful if you have rubber parts in your sprayer, mineral spirits and paint thinner may dissolve some plastic.  Check with your paint sprayers manufacturer about the best way to clean your specific sprayer. 

If that is the case, check out these alternative to mineral spirits solutions for something to use to clean your sprayer.


Soaking parts and tools in paint thinner and/or mineral spirits will degrease them with minimal effort.

For quick results, soak a rag with paint thinner or mineral spirits and wipe the area or tool you need to clean and watch the grease come right off.   

Remember to use a clean rag to wipe down your tools and parts after using mineral spirits.

Removing Paint Spills 

Even if you have a dried on paint spill, you can use paint thinner or mineral spirits to get it off!  Just soak the area for a bit and then wipe off.   

You might need to do this a few times, depending on the size or the spill and what you spilled in on. Be careful of the type of surface you are using thinners or spirits on, you don’t want to ruin or stain your surface.
