ABSTRACT:
Skin disinfectant with colorizer, plus removal of the resulting color, especially for udders of milking animals. An aqueous solution of a permanganate as colorizer, a hypochlorite as disinfectant, and an organic acid as buffer is applied in a post-milking step. The resulting color provides positive visual assurance of disinfectant application. Subsequent removal of the color can be accomplished by applyication of an aqueous solution of peroxide and an organic acid. Removal of residual color is appropriate just before the next milking not only as a cleaning step but also to ensure post-milking disinfecting, and is also effective upon the hands or other skin of persons or animals however colored with permanganate or like material.
