PROBLEM TO BE SOLVED: To provide a method for sterilizing an entire fabric product nearly uniformly for deodorization with a sterilizing agent for deodorization which acts on the entire fabric product nearly uniformly by making the sterilizing agent for deodorization to flow through the fabric product, even if the fabric product is thick, multi-layered, or folded.SOLUTION: A fabric product soaked with a sterilizing agent for deodorization is supported to enable airing, a high-speed airflow is made to flow through the fabric product to cause the sterilizing agent for deodorization to flow through the fabric product, and consequently, sterilization for deodorization is performed on the entire fabric product nearly uniformly.
