A procedure is presented for soiling detergency test cloths with particulate soil. These cloths offer advantages over most commercial soiled cloths and laboratory soiling procedures in that there is no oily material necessary for dispersion and thereby the testor obtains results which are specific to particulate soil alone. The procedure involves a wet soiling technique, followed by drying and sorting for subsequent detergency evaluation. The soil composition includes Bandybalck clay, iron silicate, and iron oxide. Detergency results are discussed.
