The addition of either a borohydride or borane complex anhydrously associated with an aldose to an inhibitor removing bath which does not contain a color reverse agent improves color balance and contributes color agent to the bath. Addition of these anhydrously associated materials avoids possible decomposition in premixed solutions.
