Patent ID: 7001773

Claim:
A method for testing a cleaning product, said method comprising applying to a hard surface from 0.1 to 10 grams of a test soil, per square meter; said test soil comprising from about 40% to 80% of at least one particulate component, from about 20% to 60% of at least one hair component, and up to about 40% of an additional fiber component, wherein the particulate component has a particle size distribution of from 1% to 10% less than 75 microns, from 10% to 30% between 75 microns and 300 microns, and from 60% to 85% greater than 300 microns; first, randomly but evenly, distributing the particulate component of said test soil to the surface; second, randomly but evenly, distributing the hair and fiber components of said test soil to the surface by separating fibers from each other into at least ten divisions of fibers and distributing these divisions of fibers to the surface; applying the cleaning product to the test surface to remove the test soil; and measuring the amount of test soil that has been removed by the cleaning product from the surface to obtain the relative efficiency of the cleaning product.
