products. In western Europe about 60% of the total white spirit consumption is used in paints, lacquers and varnishes. White spirit is the most widely used solvent in the paint industry. In households, white spirit is commonly used to clean paint brushes after use, to clean auto parts and tools, as a starting fluid for charcoal grills, to remove adhesive residue from non-porous surfaces, and many other common tasks.

Types and grades

Three different types and three different grades of white spirit exist. The ''type'' refers to whether the solvent has been subjected to

Physical properties

Type 1 white spirit is mainly used in most of Europe and Stoddard solvent is used in the US, both of which correspond to each other.

. White spirit is commonly used for cutting fluid in ultraprecision lathes (commonly referred to as diamond turning machines). White spirit is used for regripping golf clubs. After the old grip is removed, the white spirit is poured into the new grip and shaken. After the white spirit is poured on, the new underlying tape and the new grip are slid on. After an hour of drying out, the new grip and club are ready to use.


Solvent and paint thinner

, and it has inferior solvent properties. Artists use white spirit as an alternative to turpentine since it is less flammable and less toxic. Because of interactions with pigments in oil paints, artists require a higher grade of white spirit than many industrial users, including the complete absence of residual sulfur.

(also referred to as silk-screening), white spirit is often used to clean and unclog screens after printing with oil-based textile and plastisol inks. It is also used to thin inks used in making monoprints. White spirit is often used inside liquid-filled compasses and gauges. White spirits are a major ingredient in some popular automotive fuel/oil additives, such as Marvel Mystery Oil, as they are capable of dissolving varnish and sludge buildup.


Portable lanterns and stoves

Although white spirit is sometimes used as an alternative to camp fuel, such as kerosene or paraffin, in portable lanterns and camp stoves , this is highly inadvisable as typical grades of white spirit have a lower flash point than kerosene. It cannot be used as an alternative to Coleman camp fuel or white gas, which is a much more volatile gasoline-like fuel.
