Dry cleaning
Hydrocarbon — This is most like standard perc dry cleaning, but the processes use hydrocarbon solvents such as Exxon-Mobil’s DF-2000 or Chevron Phillips' EcoSolv. These petroleum-based solvents are less strong than perc and require a longer cleaning cycle. While flammable, these solvents do not present a high risk of fire or explosion when used properly. A hydrocarbon solvent also contains volatile organic compounds (VOCs) that contribute to smog.
