PROBLEM TO BE SOLVED: To provide a repowdering method of a deodorant capable of easily increasing or decreasing a deodorant performance and obtaining a stable deodorant efficiency. SOLUTION: Deodorant powder, a binder and water are mixed, molded, dried and calcined to be solidified as a deodorant 1 for air cleaning. A repowdering means 4 is applied to the surface layer of the deodorant 1 prepared and a part of the deodorant 1 is returned to be an original powder state. Thus, the solidified deodorant 1 is partially returned to be the original powder state and therefore a repowdering volume can be quantitatively controlled, repowdered deodorant powder displays such a stable deodorant efficiency as a state of a fresh product, and an effective deodorizing is carried out.
