PROBLEM TO BE SOLVED: To provide a method of washing that can simultaneously achieve the effective sterilization of an object to be washed and the prevention of scale adhesion to a washing machine. SOLUTION: In the method of washing an object made of a fibrous product to be washed, the object to be washed is treated by adding an organic peracid to a washing water when the washing water in a tub of a washing machine has a pH of 9 or less and an electrical conductivity less than 1,000μS/cm different than that of water to be used. For example, in the case when used is a continuous washing machine provided with a plurality of tubs 21-25 for washing and a plurality of tubs 26-28 for rinsing respectively disposed in alignment for continuously performing the washing operation by sequentially moving the object to be washed to each of these tubs, an organic peracid is charged into the tub 28 for rinsing in which the washing water in the tub satisfies the above conditions during the course of washing the object to be washed with use of a detergent in a plurality of tubs 21-25 for washing and rinsing the object to be washed which has been treated with the detergent in a plurality of tubs 26-28 for rinsing.
