Abstract
A bleaching composition comprising a partially saturated carrier and a bleaching agent prepared by first mixing the dry carrier with the dry bleaching agent and then adding water while continuing mixing to produce a moist powder. This powder is used in a tumbler with at least partially nonsynthetic dyed fabrics to dry bleach or fade the dye from the fabrics. Specifically, the bleaching composition is a mix of potassium permanganate as the bleaching agent and diatomaceous earth as the carrier and is tumbled with the fabric to remove the dye from the fabric. The tumbling causes repeated contact with the bleaching agent and removes the dye in the fabric.
