Abstract: This invention is a method for dry cleaning with binary vapor in which articles such as fabrics and the like are subjected to tumbling in a basket or chamber while heated air is circulated through said chamber. While being tumbled, the articles are exposed to a binary vapor consisting of water and solvent under pressure which loosens or removes debris and soils from the articles. The debris and soils are carried by the air and binary vapor to a filter where the soils and debris are captured with the binary vapor continuing on to a condenser where the binary vapor is converted to binary liquid. Upon conclusion of the cycle the articles are removed from the chamber.

Abstract: This is a business model algorithm for a dry cleaning system utilizing organo silicone-based solvents and incorporating a business model algorithm for the conversion of dry cleaning equipment and machines which were previously designed for and used with other solvents. The algorithms include distinct studies of each individual machine or piece of equipment being converted and the application of particular techniques to accommodate the differences in the solvents including the plumbing of the machines, the safety factors involved, and special training and instruction of the equipment operating personnel.
