ABSTRACT:
A test method is disclosed that can be used to test cleaning products. The test method includes applying a known amount of test material to a surface, cleaning the surface and calculating the amount of allergens picked-up from the surface. The calculated amount of allergens picked-up is then corrected for several measurable variables to provide a more accurate determination of the percentage of allergens picked up with the cleaning product.
