ABSTRACT:
The present invention comprises a dry cleaning system and method, in which dry cleaning machinery is used in conjunction with a specific solvent which is derived from an organic/inorganic hybrid (organo silicone). Such solvent is used in combination with an organic and/or organo-silicone-based detergent which is specifically tailored for working in conjunction with the solvent to afford optimal cleaning. In a preferred embodiment, the method comprises the steps of loading articles into a cleaning basket; agitating the articles in the solvent and detergent composition in which they are immersed; removing most of the solvent and detergent composition; centrifuging the articles; heating the articles and remaining composition and creating vapors, condensing vapors and optionally reducing the pressure to dry the articles, recovering and recycling solvent and removing the articles from the basket after cooling the articles.
