A method of dry cleaning fabrics using a dry cleaning system is described. The system comprises densified carbon dioxide and a surfactant in the densified CO2. The surfactant has a polysiloxane, a branched polyalkylene oxide and a halocarbon group which is a functional CO2-philic moiety connected to a CO2-phobic functional moiety. The surfactant either exhibits an HLB of less than 15 or has a ratio of siloxyl to substituted siloxyl groups of greater than 0.5:1.
