    Benzene is a highly volatile aromatic hydrocarbon solvent which is present in most petroleum distillates such as Stoddard solvent and mineral spirits. Recent advances in the purification process for these solvents has reduced the benzene content significantly, but it is still present in products such as WD-40 and Liquid Wrench as well as many solvents used in the printing industry and elsewhere.
