Mineral spirits, white spirits, or mineral turpentine are petroleum-derived solvents used in painting. They are insoluble in water and are used in various products like aerosols, paints, lacquers, varnishes, and asphalt. Mineral spirits are the most widely used solvent in the paint industry, accounting for 60% of white spirit consumption in Western Europe. They clean paint brushes, auto parts, and tools and remove adhesive residue from non-porous surfaces. Odorless mineral spirits (OMS) are refined to remove more toxic aromatic compounds, making them suitable for oil painting applications.
