Abstract
A cleaning indicator including a substrate having an image upon it that can be interrogated to assist in monitoring a process for washing articles in a washing machine system. The image can be a printed image, which in turn is covered at least partially by a test soil to be removed by the washing process. Alternatively, the test soil can be formed into an image on the substrate. The cleaning indicator can be imaged before the start of a washing process to allow the washing process to proceed only if the appropriate image is observed. The cleaning indicator can be imaged during operation of the washing process, and when a criterion for cleanliness is met, the washing process can be automatically terminated. A washing system for using the cleaning indicator in an automated washing process is also disclosed.
