The invention is directed to a dry-cleaning article suitable for use in the home. The article is characterized by a sheet that is permeated with a composition including 51 - 98 % by weight of organic solvent such as paraffins, olefins, acetylenes or mixtures thereof, 1 - 35 % by weight of water, and 1 - 14 % by weight of emulsifier to allow the water to be uniformly mixed into the solvent. The composition can also include 1 - 5 % by weight of perfume for scenting clothing, and 1 - 5 % by weight of nonionic and/or anionic surfactant to provide additional stain removal capability of the composition. The invented composition is thus organic-solvent-based and is particularly effective to remove body or cosmetic oil stains from garments. The invention is also directed to the composition and methods for using the sheet in a drying machine.
