In the next several issues I’ll be explaining the processes incorporated in the modern dry cleaning machine including distillation, washing and extraction, drying, and control. The components used in these processes, and how these components are combined and coordinated to clean garments. DISTILLATION Distillation is a process used to purify a liquid, in our case
