A reliable method for testing the performance of detergent compositions, particularly from the standpoint of the redeposition of soils on fabrics during the laundry wash cycle, which comprises subjecting a clean control fabric swatch to multiple washings, each washing conducted in a solution of the detergent composition and in the presence of one or more pre-soiled fabric swatches, and then analyzing the control swatch for soil content, for example, by light reflectance or radiotracer methods.
