Abstract: A cleaning composition includes a detectable substance which is relatively stable in the cleaning composition, for indicating whether the cleaning composition has been thoroughly removed from a vessel following a cleaning process. For pharmaceutical applications, the detectable substance is preferably a low-foaming surfactant that is detectable by high performance liquid chromatography at concentrations of around 10 ppm, or less.
