This name refers to a class of petroleum-based chemicals. They are clear and colorless, and in this case, odorless. A common name for mineral spirits is paint thinner, although they can also be referred to as mineral turpentine. These chemicals are both toxic and flammable. Given that these chemicals are called paint thinners, that is one primary application for them. However, they can also be used to create various solvents and cleaners as well. Mineral spirits are excellent not just for dissolving paint, but other forms of grease and dirt. Odorless varieties are better because they do not produce harsh fumes and they dry more evenly. Goggles, gloves, and a breathing mask should be worn when handling mineral spirits. They can irritate the skin and eyes, and they can be harmful if swallowed. The vapors produced by mineral spirits can also be an irritant, and they are highly flammable. Mineral spirits should be stored in a cool, dry area.
