Soil Removal in Automatic DishwashingDepartment of Consumer Sciences and Retailing, School of Consumer and Family Sciences, Purdue University, West Lafayette, Ind. 47907
Department of Consumer Sciences and Retailing, School of Consumer and Family Sciences, Purdue University, West Lafayette, Ind. 47907 During preliminary testing, an egg yolk-calcium chloride complex was selected as a promising dishwasher test soil, and various factors were identified as being related to its removal in dishwasher washing of dishes. Data for statistical analysis were collected in con trolled laboratory tests using five water temperatures, five levels of calcium chloride in the yolk soil solution, two dishwasher positions, and two wash times. A series of tests was per formed in deionized water and a second series in hard water. Difficult soil removal was found to be related to all the main variables studied and the soil developed shows promise as a dishwasher test soil.
