There is disclosed an aqueous composition for removing or reducing the intensity of dyes in dye transfers and the intensity of dyes used by photo retouchers on transparencies and color prints. The composition comprises, per 100 parts by weight of water, from about 1 to about 10 parts by weight of a thiourea and from about 5 to about 20 parts by weight of an ammonium nitrate compound. Application of this composition to dye transfers and/or to dyes used by photo retouchers on transparencies and color prints proportionally removes magenta, cyan and yellow dyes therefrom.
