Stevenson Painting Solvent is an aromatic hydrocarbon. It is a more active solvent than turpentine or mineral spirits. Good for dissolving artists resins such as damar and elvacite. It is over-kill to use this for cleaning brushes and mixing with oils. Consider OMS for painting. We offer a number of non-toxic solution for brush cleaning which are safer.
