Abstract

An artificial test soil is composed of particulate, hair, and fiber components, wherein the particulate component consists of mineral, food, and plant materials, so chosen and proportioned as to correlate to a typical soil found in the home. The test soil may be used to test cleaning products by application of a known amount thereof to a surface, cleaning the surface, and determination of the amount of soil removed from the surface.
