    Abstract: Stained areas (2) of fabric are separately treated with a non-aqueous cleaning composition, followed by an aqueous cleaning composition, and by using a hand-held device (1) which is rocked back and forth on said stained areas (2). The fabric (3) is then placed in a bag or other container, together with a sheet substrate releasably containing an aqueous cleaning composition. The bag is tumbled in a hot air clothes dryer to clean and refresh the entire fabric (3).

    Abstract: A process for bleaching fabrics or garments which produces a uniformly colored product with relatively few, less pronounced streaks is disclosed. The process requires fewer steps and increases efficiency over previous processes, while at the same time decreases the number of excessively streaked products which do not satisfy quality control standards. A preferred embodiment of the process, suited to denim fabrics or garments, comprises the steps of desizing the fabric or garment, and thereafter, without turning garments, immersing the fabric or garment in an aqueous solution containing from about 0.01 to about 10 grams per liter of a polyacrylic acid, and then adding a bleaching agent to the aqueous solution to produce a bleach bath. The fabric or garment is maintained in the bleach bath for a time sufficient to bleach the fabric or garment.
