Abstract: Systems and methods for performing quantitative detection and analysis of cleanliness and cleanliness levels of components, or pieces of equipment, are disclosed. A cleaning system may have a cleanliness information acquisition module which may acquire, inter alia, optical information about a piece of equipment and a computer-based processing unit may determine a level of cleanliness, an extent to which the piece of equipment is contaminated with a contaminant, and an appropriate cleaning methodology to employ to clean the piece of equipment, using, for example, a cleaning composition which may include a cleaning agent. The cleaning system may execute the cleaning methodology, and once again determine the cleanliness level of the piece of equipment. The cleaning system may also detect the presence or the absence of defects in the piece of equipment. The information collected may also be stored in a database for future reference.
