To provide a method for treating a fiber product by which excellent softening effects can be imparted even in a state in which the amount of cleaning water or rinsing water based on the fiber product is little, and the rinsing is not carried out sufficiently.
The method for treating the fiber product includes (a) 0.1-20 ppm of a macromolecular compound containing specific monomer units (A) and (B) in a specified molar ratio, (b) 10-300 ppm of one of more kinds of compounds selected from a specific tertiary amine or an acid salt thereof and a quaternary ammonium salt, and (c) 3-200 ppm of a calcium ion and/or a magnesium ion to be contained in the rinsing water, when treating the fiber product by a cleaning step for cleaning the fiber product by using the cleaning water containing water and an anionic surfactant in a mass ratio of the fiber product to the cleaning water regulated so as to be from 1/3 to 1/15, and a rinsing step for rinsing the fiber product after the cleaning step with the rinsing water in a mass ratio of the fiber product to the rinsing water regulated so as to be from 1/3 to 1/15.
