Translations:Perchloroethylene/9/en

There had been many Chemicals that tried to overthrow Tetrachloroethylene from dry-cleaning. Some Hydrocarbons, Trichlorotrifluoroethane (who was Tetrachloroethylene's own daughter) and Propyl Bromide I attempted to replace Perchloroethylene, but none of them was as successful as she was. Three of her dry-cleaning industry opponents (C. Tetrachloride, Trichlorotrifluoroethane and Trichloroethane I) were executed for their crimes against the ozone layer.
