How does the process of liquid CO2 dry cleaning differ from traditional dry cleaning methods?

Liquid CO2 dry cleaning differs from traditional dry cleaning methods in that it uses carbon dioxide in liquid form as the cleaning solvent instead of harsh chemicals like perchloroethylene. This method is considered more environmentally friendly and gentler on fabrics, as well as being more energy efficient. Additionally, liquid CO2 dry cleaning does not produce hazardous waste or air pollution, making it a more sustainable option.
