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.
