The invention also provides a method of cleaning an article (e.g., an electrical, plastic, or metal part) in a vapor degreaser using the solvent mixture. The solvent mixture of the invention is non-flammable, non-corrosive, and non-hazardous. In addition, it has a high solvency and a very low ozone depletion potential. Thus, using the solvent mixture of the invention, oil, grease, rosin flux, and other organic material can be readily removed from the article of interest in an environmentally safe manner.
