Mineral spirits and paint thinners are indispensable solvents for thinning oil-based paint, stains, and varnishes, as well as for cleaning paint equipment. Paint thinner is a general term for any solvent that can thin paint. Mineral spirits, on the other hand, are mineral-based paint thinners made from petroleum distillates with no additives. Odorless mineral spirits are heavily refined to remove harmful chemicals, while pure mineral spirits are not. Odorless mineral spirits are a great choice for cleaning paintbrushes as they have similar properties to turpentine without the harmful pollutants or noxious odors.

Mineral spirits are derived from minerals, specifically petroleum
Mineral spirits, also known as white spirits, are derived from petroleum. They are a type of petroleum-based solvent, made of 100% petroleum distillates and have no additives. Mineral spirits are clear, non-sticky, and relatively odor-free. Odorless mineral spirits have been further refined to remove toxic aromatic compounds, making them safer for use in applications such as oil painting. They are indispensable solvents for thinning oil-based paint, stains, and varnishes, as well as for cleaning paint equipment and brushes.
Mineral spirits are often confused with paint thinner, and while they share some similarities, they are not the same product. Paint thinner is a general term that describes the function of a product rather than its composition. It can refer to a wide range of products capable of thinning paint, including pure mineral spirits, blended mineral spirits, turpentine, acetone, naphtha, and many others. Paint thinner can even refer to products with no petroleum content, such as water or citrus-based thinners.
The key difference between mineral spirits and paint thinner lies in their composition and refinement. Mineral spirits are derived from petroleum and are typically 100% mineral spirits with no additives. In contrast, paint thinner is often a less refined mineral spirit with added benzene for improved solvency and aroma. Paint thinner is also generally more affordable than mineral spirits, costing about 40-50% less.
While mineral spirits are highly effective in thinning oil-based paints and varnishes, they are non-renewable resources. The methods used to extract the petroleum for mineral spirits can have damaging effects on the environment, including the earth and the ozone layer. As a result, some people may prefer to use bio-based solvents as a safer alternative to mineral spirits.
In summary, mineral spirits are derived from minerals, specifically petroleum, and are used for thinning and cleaning oil-based paints, stains, and varnishes. They are distinct from paint thinners, which is a broader term for a range of products that thin paint, including those with and without petroleum content. Mineral spirits are clear, odourless, and highly effective, but they are non-renewable and can have environmental impacts.

Paint thinner is a general term for any substance that thins paint
Mineral spirits are derived from petroleum and are heavily refined during production to reduce toxic volatile organic compounds (VOCs) and sulfur. Odor-free or odorless mineral spirits have undergone additional filtration to remove harmful chemicals, making them a safer option for homeowners with children or pets. Paint thinners, on the other hand, are often minimally refined, resulting in a solvent that retains most of its original toxic VOCs. Due to the lower VOC content in mineral spirits, their odor is less potent or even nonexistent in the case of odor-free mineral spirits.
The distinction between mineral spirits and paint thinner lies primarily in their composition and function. Mineral spirits describe the product's composition, specifically referring to a mineral-based paint thinner made from 100% petroleum distillates with no additives. In contrast, paint thinner refers to the product's function and can encompass a wide range of solvents capable of thinning paint. Paint thinner can be mineral-based but often contains additives, resulting in a more odorous and volatile product compared to pure mineral spirits.
In terms of performance, both mineral spirits and paint thinners effectively thin oil-based paint and clean brushes and other painting tools. However, paint thinners with stronger solvency, such as turpentine, can even remove dried paint, while mineral spirits are typically limited to removing wet paint. Paint thinned with mineral spirits tends to dry to a smoother and more even finish. Additionally, mineral spirits evaporate more slowly, making them better for soaking painting tools and reducing the likelihood of noticeable brush strokes.
While mineral spirits are generally less toxic and less odorous than alternative paint thinners, they tend to be more expensive. Paint thinners are often cheaper, but their stronger fumes require users to work in well-ventilated areas. The higher cost of mineral spirits is due to the additional energy required to purify and achieve a more refined content.

Odorless mineral spirits are heavily refined to remove harmful chemicals
Mineral spirits and paint thinners are indispensable solvents for thinning oil-based paint, stains, and varnishes, as well as for cleaning paint equipment. Mineral spirits are less toxic and less odorous than other paint thinners. An odorless version is also available.
Paint thinner is a blanket term for any solvent that can thin paint. Paint thinners can be mineral-based, with additives, or they can be derived entirely from pine tree oleoresins with no petroleum content, such as turpentine. Turpentine has a stronger solvency than mineral spirits and can remove dried paint.
Mineral spirits are heavily refined during production to reduce toxic volatile organic compounds (VOCs) and sulfur. Odor-free mineral spirits have no toxic compounds, eliminating harmful pollutants from the home. Mineral spirits are also slower to evaporate, making them better for soaking brushes and rollers.
Odorless mineral spirits are a great choice for cleaning paintbrushes as they have similar properties to turpentine without the harmful pollutants or noxious odors. They are also excellent for thinning finishing oils and cleaning up sticky residue left by oil-based paints.
However, mineral spirits are generally more expensive than alternative paint thinners, and they are not suitable for use with latex paint.

Paint thinner is cheaper than mineral spirits but has strong fumes
Paint thinner and mineral spirits are indispensable solvents for thinning oil-based paint, stains, and varnishes, as well as for cleaning up paint equipment and oily materials. The term "paint thinner" is a general term that can refer to any product that thins paint, including mineral spirits, turpentine, acetone, naphtha, and many other products. Mineral spirits, on the other hand, refer specifically to a product made from 100% petroleum distillates with no additives.
While paint thinner and mineral spirits are interchangeable products, there are some key differences between the two. Paint thinner typically has more solvency than mineral spirits, allowing it to clean quickly and even remove dried paint. It is also less expensive, usually costing between $15 and $20 per gallon, compared to mineral spirits, which can cost around $20 to $25 per gallon. However, due to its higher solvency, paint thinner may not be suitable for thinning paint, as it can affect the final consistency and performance of the paint.
Mineral spirits, on the other hand, are less refined and have a slower rate of evaporation, resulting in a smoother and more level coat of paint. They are also lower in toxins and odors, making them preferable for indoor use. Odorless mineral spirits are also available, which have undergone additional filtration to remove harmful chemicals and provide a safer alternative for those concerned about indoor air quality.
While paint thinner is cheaper and more readily available, it is important to consider the specific requirements of your project. Mineral spirits may be preferred when a slower-drying, smoother finish is desired, or when working indoors due to their lower toxicity and odor. Paint thinner may be preferred for outdoor projects or when a faster-drying, more economical option is needed.
In summary, while paint thinner is cheaper than mineral spirits, it is important to consider the specific needs of your project. Both products have their advantages and disadvantages, and the best choice will depend on factors such as desired finish, indoor or outdoor use, and budget.
