Mineral spirits, a petroleum-derived solvent, are employed across a spectrum of applications primarily for thinning oil-based paints, cleaning brushes and equipment, and degreasing surfaces. For instance, adding a small amount to oil-based paint can reduce its viscosity, improving its flow and application. Similarly, brushes saturated with oil-based paint can be effectively cleaned by submerging them in the solvent and agitating to remove residue.
The utility of this solvent lies in its relatively low toxicity and slow evaporation rate compared to other solvents, making it a safer and more manageable option for many tasks. Historically, it has been a staple in workshops and studios, offering a reliable method for maintaining tools and achieving desired finishes in painting and other projects.
