  • Patent number: 5632780
    Abstract: 1,2-Octanediol is used to clean soiled fabrics. Thus, cleaning compositions comprising 1,2-octanediol, preferably in combination with solvents, are impregnated into carrier sheets. The sheets are tumbled with soiled fabrics inside of a plastic bag. The resulting home dry cleaning process leaves the fabrics clean and refreshed.

  • Patent number: 5547476
    Abstract: A home dry cleaning process is provided. Thus, a carrier sheet releasably impregnated with solvents such as butoxy propoxy propanol, 1,2-octanediol as a wetting agent, water and an emulsifier is placed in a plastic bag with soiled garments and tumbled in a hot-air clothes dryer. The garments are cleaned and refreshed.
