The purity and low toxicity of mineral spirits allow it to expand its role well beyond a small paint job. Mineral spirits are a more versatile all-around cleaner. * Keep in mind that, regardless of which solvent is used, the paint should still be fresh or wet when these solvents are applied for cleaning purposes the effect of both diminishes once the paint has dried on a brush or roller. It boasts a slower rate of evaporation, and paint thinned with mineral spirits dries into a slightly smoother, more level coat on surfaces than paint thinned with faster-evaporating paint thinner. But here, too, mineral spirits is more desirable.

So, the higher cost of odor-free mineral spirits may be worth it if optimal indoor air quality is a priority for you. Cleaning paint brushes or thinning paint for a furniture refresh typically requires no more than four to six ounces of solvent, so you shouldn’t need to purchase either any type of paint thinner in bulk amounts or very frequently. Now that cost differential may seem significant at first blush, but it’s minimal in the scheme of things.

Meanwhile, the less labor-intensive production process for other paint thinners turns out a less-refined composition at a lower cost. Mineral spirits require extra energy to purify and achieve a more refined content, accounting for its higher average cost. Paint thinner is cheaper.Ī gallon of mineral spirits goes for $10 on average, and odor-free mineral spirits costs on the order of $15 per gallon-nearly double the cost of many paint thinners at $8 per gallon. Smelly or not, do-it-yourselfers should wear a respirator and work in a well-ventilated area when handling any solvent since fumes can negatively affect respiratory health if inhaled in high enough concentrations. Meanwhile, other paint thinners come with a more noxious odor that takes a while to air out. While mineral spirits and other paint thinners all emit an unpleasant kerosene-like odor due to the VOCs they contain, the lower VOC content in mineral spirits means its odor is less potent (or nonexistent in the case of odor-free mineral spirits). Many other paint thinners, on the other hand, are minimally refined during production, resulting in a solvent that retains most of its original toxic VOCs like toluene and benzene. In the case of odor-free mineral spirits, which are readily available in home centers, these toxic compounds have been completely eliminated! These solvents allow homeowners with kids or pets to rest easy, knowing they aren’t introducing as many harmful pollutants into the home during paint projects. Mineral spirits are heavily refined during production to reduce toxic volatile organic compounds (VOCs) and sulfur. In general, many DIYers find mineral spirits easier to work with than some of the other paint thinners, which can be quite hazardous and irritating.

Mineral spirits is a heavily refined distillation of petroleum that is used to thin oil-based paints and to clean brushes and rollers. While, again, mineral spirits are simply a type of paint thinner, mineral spirits paint thinner has characteristics that distinguish it from other products such as turpentine or acetone.
