1. A bleaching element for distressing fabric, comprising:

  • an abrading device selected from the group consisting of pumice stone, silica sand, diatamatious earth, and dicalcium phosphate, the abrading device being impregnated with;

    (I) a bleaching agent having a molecular structure comprising an element selected from the group consisting of chlorine and manganese, and (II) an acid;

    the bleaching element being made according to a process comprising the steps of;

    soaking the abrading device in an aqueous solution for a time sufficient for the aqueous solution to impregnate the abrading device, said aqueous solution consisting essentially of the bleaching agent, the acid, and water, the bleaching agent being present in an amount from about 1 to 25% by weight of the aqueous solution and the acid being present in an amount from about 0.5 to 50% by weight of the aqueous solution;

    thereafter, withdrawing the abrading device from the aqueous solution; and

    drying the abrading device,whereby the bleaching agent is present in the bleaching element in an amount sufficient to bleach the fabric to be distressed when the bleaching element is tumbled with the fabric in a tumbler, and the acid is present in the bleaching element in an amount sufficient to eliminate latent yellowing of the fabric due to exposure of the fabric to ultraviolet light.
