  • Patent number: 6048368
    Abstract: The present invention provides a more effective method of treating a spot or stain on a textile fabric, the method comprising the steps of: applying a detergent composition to the spot or stain; placing an absorbent layer adjacent to one side of the textile fabric in the region of the spot or stain; and applying heat, pressure, or heat and pressure, to the opposing side of the textile fabric in the region of the spot or stain, preferably in the presence of a hydrophilic solvent, or water, so that some or all of the spot or stain is absorbed into the absorbent layer. The detergent composition can be applied to the textile fabric using a container having a cap to which a foam pad is secured. The cap has a small opening through which the detergent composition can pass.
