A method of reducing dye fading of fabrics in laundry bleaching compositions is provided, comprising contacting stained fabric, in a wash liquor, with a bleaching composition that comprises a specified bleach catalyst. The bleach catalyst comprises a ligand which forms a complex with a transition metal, the complex catalysing bleaching of stains by atmospheric oxygen, and the composition is substantially devoid of peroxygen bleach or a peroxy-based or -generating bleach system. The bleaching composition provides effective bleaching performance on fabric stains without causing unacceptable dye damage or dye fading of the fabrics after repeated washes. |
