Safety First Everyone!
Make sure you’re working in a well ventilated area with some air flow. If you’re working inside, use fans that vent to the outside and pull fresh air in and open the windows.
Don’t get it on your skin, and remember it’s flammable!
Store your unused chemicals away from heat sources, in a container that is 3/4 full. Solvents and chemicals give off vapors that need room to expand when stored.

What is Paint Thinner?
What is paint thinner used for? Thinner is a solvent used to thin oil based paints and primers. It is also used to clean up afterwards. It can also be used to degrease car and bike parts.
Thinner takes a thick paint and makes it more watery so that it can be sprayed through a paint sprayer tip.
When people talk about thinner, they are usually referring to mineral spirits. Each brand of thinner has a different combination of chemicals, and one of those is mineral spirits.
Some work better than others. You can even buy odorless thinners.
What can I use as Paint Thinner?
Straight up mineral spirits can be used as paint thinner. They have less odor than traditional thinners and are a bit better at removing and thinning paint.
If you can’t find mineral spirits in your area, check out these alternatives you can use to get your projects done.
Thinners are typically cheaper to purchase because they are not a refined as mineral spirits and contain other types of solvents, depending on the brand.
Each brand has different ratios of solvents and may work differently, smell worse, and be more volatile.
They would work great to clean large areas or for cleaning your tools.
Pure acetone can also be safely used.
Turpentine can also be used as a thinner. Check the label of the paint you plan on thinning to make sure which product the manufacturers says works best to thin their paints.
|What Can I Use as Paint Thinner?|
|Water (only for latex and water based paints!)|
Thinner can remove oil-based paint from brushes and other equipment but only while the paint it still wet.
According to Truevalue.com, make sure the paint you are thinning is not cold but at room temperature. Paint will be thicker if it’s cold and you will use too much thinning agent.
Acetone is often the only solvent that is strong enough to dissolve paint after it has dried.
