Abstract
A method for laundering a textile wash load is provided for use in a vertical axis washing machine in which a concentrated detergent solution containing a detergent concentration of 0.5% to 4% by weight is continuously applied to a spinning wash load for a predetermined time period to thouroughly wet the clothes load. The amount of detergent solution used is only slightly in excess of the amount required to saturate the clothes load at the given rotational speed. After the time period, additional water is added to the solution to dilute it to a normal concentration and then mechanical agitation and rinsing steps are conducted to complete the wash cycle.
