14、formance of a test product depends on theparticular combination of test soil and substrate.Soils andsubstrates to be cleaned should be selected as pairs.The usualcriteria for appropriate soil/substrate combinations are:relativeease of discriminability among cleaners to be tested;reproduc-ibility of
