ABSTRACT:
A washing method has a nonaqueous washing process of washing an object to be washed using a nonaqueous solution, an intermediate washing process of washing the object to be washed using a solution having solubility relative to both an aqueous solution and the nonaqueous solution after said nonaqueous washing process; and an aqueous washing process of washing the object to be washed with the aqueous solution after said intermediate washing process. When an intermediate washing process is performed between the nonaqueous washing process and the aqueous washing process, the nonaqueous solution adhered to the object to be washed in the nonaqueous washing process is removed in the intermediate washing process, and replaced by a solution having solubility relative to both the nonaqueous solution and the aqueous solution, so as to prevent the nonaqueous solution from being introduced into the aqueous solution used in the aqueous washing process.
