Abstract
A method is provided for selectively bleaching dyed, bleachable cotton garments. The garments are tumbled in damp condition with reuseable pre-formed solid pellets of limited porosity having abradable surfaces. The pellets comprise substantially water-insoluble cemented aggregates of mineral particles with a finely-divided particulate bleaching aent imbedded therein. The bleaching agent, which preferably is substantially uniformly distributed in the pellets, bleaches the garments by surfaces of the pellets wearing away during the garment tumbling to release the bleaching agent as the pellets contact the garments.
