Abstract
An improved wash process is provided for a horizontal washer wherein a concentrated detergent solution is applied to a spinning wash load, the load is spun to effect a greater than one gravity force to maintain the clothes load against the basket wall, and the concentrated detergent solution is recirculated through the clothes load for a first period of time. After the first period of time, the detergent solution is diluted somewhat, although the concentration remains above a normal concentration of 0.06 to 0.28%. The wash chamber will then be spun to effect less than a one gravity centrifugal force on the fabric such that the fabric will tumble in the wash chamber. The lesser concentrated detergent solution will then be recirculated on to the fabric during a second time period.
