Solid chlorinating agents can be stored highly stably and safely in a closed system for a long period of time without discoloring or deterioration, when a storage stabilizer of alumino-silica gel obtained from allophane incorporated with active carbon is placed in the ambient atmosphere enclosing the chlorinating agents, preferably not in direct contact with the agents. In addition, the agents do not cause damages on the surface and material of, or breakdown of, the container constituting the closed system, and no offensive odor is generated upon opening even after a prolonged storage.

Method of storing a solid chlorinating agent

Fungi growing on a hide are removed by immersing the hide in an aqueous solution of chlorinated isocyanuric acid or salt in a solution of chlorinated isocyanuric acid or salt in a halogenide of an aliphatic hydrocarbon having one to three carbon atoms or in a ketone or ester represented by the general formula: ##STR1## (wherein, R.sub.1 denotes an alkyl group having one to three carbon atoms and R.sub.2 an alkyl group or alkoxy group having one to three carbon atoms).
