In some embodiments, the composition includes at least one organic solvent, with the at least one organic solvent forming the greatest weight percentage of the active components in the composition. In some embodiments, the composition also may include water and/or at least one surfactant, emulsifier, perfume, and/or application-specific composition. In some embodiments, the article includes a dispenser from which the composition is selectively dispensed onto a dry garment or other object to be cleaned. In some embodiments, the dispenser includes an internal chamber containing the composition, and the composition is dispensed onto objects prior to placing the objects in a drying machine. ## Claims ### Claim 1 A method for cleaning dry objects, the method comprising: dispensing, from an internal chamber of a dispenser, a dry-cleaning composition onto a dry object to be cleaned in a drying machine, wherein the object to be cleaned is not suitable for laundering in a household washing machine, wherein the dispenser is adapted to selectively dispense the dry-cleaning composition directly onto the object to be cleaned, wherein the dispenser is selected from the group consisting of an aerosol spray vessel, a pump-actuated spray vessel, and a pressurized spray vessel, wherein the dry-cleaning composition comprises active components, and further wherein the active components comprise at least one organic solvent that forms at least 50 wt % of the active components in the dry-cleaning composition;

placing into the drying machine the garment that contains the fabric-treatment composition dispensed from the dispenser, wherein the drying machine is a household-type, non-pressurized drying machine normally adapted to dry wet garments from a washing machine; and tumbling the garment that contains the fabric-treatment composition from the dispenser with heated air in the drying machine to clean the garment with the fabric-treatment composition, wherein the tumbling includes permitting the heated air in the drying machine to contact the garment as the garment is tumbled with the heated air in the drying machine. ### Claim 12 (depends on 11) The method of claim 11, wherein the dispensing occurs prior to the placing. ### Claim 13 (depends on 11) The method of claim 11, wherein the drying machine has a maximum operating temperature, and wherein the fabric-treatment composition has a flashpoint greater than the maximum operating temperature. ### Claim 14 (depends on 11) The method of claim 11, wherein the fabric treatment composition includes at least 25 wt % water. ### Claim 15 (depends on 11) The method of claim 11, wherein the active components further include at least one glycol. ### Claim 16 (depends on 15) The method of claim 15, wherein the active components further include at least one stain remover adapted to remove one or more of ink, rust, and red wine. ### Claim 17 A method for cleaning dry objects, the method comprising: dispensing from an internal chamber of a dispenser, a fabric-treatment composition onto a garment to be treated in a drying machine wherein the garment is not suitable for laundering in a household washing machine, wherein the dispenser is adapted to selectively dispense the fabric-treatment composition directly onto the garment, wherein the dispenser is selected from the group consisting of an aerosol spray vessel, a pump-actuated spray vessel, and a pressurized spray vessel, wherein the fabric-treatment composition comprises active components, and further wherein the active components comprise at least water, a dewrinkler, and an odor-removing substances; placing the garment that contains the fabric-treatment composition from the dispenser into an air-permeable container through which heated air may freely flow when the garment and the container are tumbled in the drying machines;
