Abstract:
1. A method of determining the amount of allergens picked up by a cleaning product from a surface, the method comprising the steps of: determining a deposition efficiency of a process used to deposit test material onto a surface; determining an extraction efficiency of a process used to extract allergens from a cleaning product that is used to remove the test material from the surface; applying the test material to the surface; removing the test material from the surface with the cleaning product; extracting allergens from the cleaning product; determining a percentage of allergens removed from the surface; and determining a pick-up efficiency for the cleaning product from the percentage of allergens removed; and modifying the pick-up efficiency by the deposition efficiency and the extraction efficiency to obtain a corrected pick-up efficiency for the cleaning product, wherein the corrected pick-up efficiency is defined by the equation: wherein PU is the pick-up efficiency; EX is the extraction efficiency; and DE is the deposition efficiency; and wherein PU is defined by the equation: wherein C V M C
