Abstract
An improved liquid carbon dioxide dry cleaning system containing an improved dry cleaning fluid. The dry cleaning fluid contains an antistatic agent for dissipating static charge on members or garments generated by friction during cleaning thereof. The concentration of the antistatic agent is typically less than 1 percent. Static charge present on the members or garments that are cleaned is transferred through the dry cleaning fluid to ground. This transfer of charge minimizes static charge buildup on the members or garments and suspended soil redeposition onto the members or garments. An odorizing agent or fragrance, and/or a deodorizing agent may be added to the cleaning fluid.
