  Any water may be used as water for preparing the cleaning liquid. For example, tap water, ion exchange water, well water, river water and the like can be mentioned. Moreover, as water hardness suitable for washing | cleaning, 1 degree DH or more and 10 degrees DH or less are mentioned by German hardness.

  The temperature of the cleaning liquid is 0 ° C. or higher in terms of improving the cleaning rate, preferably 3 ° C. or higher, and more preferably 5 ° C. or higher. And the temperature of the cleaning liquid is 35 ° C. or lower, preferably 30 ° C. or lower, more preferably 15 ° C. or lower in terms of maintaining the texture of the fiber without dropping too much oil contained in the fiber itself constituting the clothing. 10 degrees C or less is more preferable. The cleaning method of the present invention is effective for removing sebum stains even when clothes are washed at a low temperature of more than 0 ° C., more than 3 ° C. and not more than 8 ° C., as in winter cleaning. Excellent detergency and can impart excellent antibacterial properties to clothing.

  In recent years, washing machines have become larger, and the ratio of the bath ratio expressed by the ratio of the mass of clothing (kg) to the amount of washing liquid (liter), that is, the amount of washing water (liter) / the mass of clothing (kg) (hereinafter referred to as this The ratio may be the bath ratio). When the bath ratio is reduced, it is said that when a household washing machine is used, the mechanical force due to stirring is not easily transmitted to the clothing, and the cleaning power is reduced. The garment washing method of the present invention can maintain detergency even under washing conditions with a small bath ratio. In the garment washing method of the present invention, the bath ratio is preferably 4 or more, more preferably 5 or more, in terms of detergency.
