This is when mineral spirits come in handy.
They soften the stain, making it easy for you to clean, and restore the wood surface. All you need to do is to let a spirit-soaked rag sit on the stain for a few minutes, and then just wipe everything away.

Prepare Wood for Staining
Another beneficial feature of mineral spirits is that they can be used for getting your wooden piece for staining. See, once you are done carving, for example, you need to stain and finish your wood pieces.
But before you can do that, you need to sand your piece down first. It will help to get rid of all the carving marks thus making the surface smoother.
But how can you clean your wood after sanding, some of you may ask? You know for sure that sanding helps to get rid of scuff marks and carving impurities.
Nevertheless, it leaves lot of sawdust behind. This is why, if you make an attempt to stain your wood right after yo are done sanding, you risk trapping this sawdust in the stain. As a result, it will become a part of the final piece!
This is why, if you strive for a clear surface, you need to use mineral spirits. Gently wipe down all wooden surfaces with a rag that is dampened with spirits, and it will do the trick!

Moreover, since using mineral spirits for cleaning is a relatively delicate process, you won’t leave marks on the wood. In comparison, those marks would be left if you had to be rougher.
This is especially important when you are working with a softwood that shows marks easily.
Show Wood Grain
Those who do wood carving know very well that, if you are working with wood and want to make sure that the finished piece will look super aesthetic, you need to choose a wood with a grain pattern that you like.
However, there is the challenge that you will experience. See, when picking out the wood, the grain pattern you see is not necessarily the pattern that will remain after you have completed and finished the piece.
This is why you need to be able to highlight the wood grain of your chosen wood piece in a way that is similar to what it will look like after finishing.
Mineral spirits are a great option for this. They don’t raise the grain of the wood.
All they do is highlight it temporarily. It allows you to get an idea of what you’re working with and adjust your design if need be.
Clean Oils From Oily Woods
We don’t only mean oils that end up on your wooden piece by accident. As you probably know, some wood types, such as purpleheart and rosewoods, can be extremely oily by their nature.
This is why they are rather challenging to work with, especially if you are using expensive tools that can gum up due to the oils in the wood.
However, if you wipe your wood piece down with mineral spirits before you start working with it, you can remove that oily residue from the wood surface.
The spirits will make your wood easier to work with, however, you need to note that this does not affect the inside part of the wood piece!
And even if you use mineral spirits, you will still need to finish the item with an evaporative finish or a sealant. Like this, you will protect it long-term.
Like this, now you know what exactly mineral spirits are used for on wooden surfaces and wooden pieces.
So if you decide to try yourself as a wood carver, make sure that you have a bottle of this liquid at hand all the time!
