Cleaning disinfection and indicator agent

Abstract

A cleaning, disinfection, and indicator agent comprising a water-soluble permanganate, particularly for mixture with an agent for ensuring an alkaline milieu having a pH value of at least 11, which, in addition to the water-soluble permanganate, contains a further oxidizing agent, whose oxidation potential is above that of manganese VII to manganese VI, pH buffer substances, preferably primary and/or secondary alkali carbonates such as sodium carbonate and/or sodium hydrogen carbonate, as well as oxidation-resistant polyphosphates. Furthermore, methods for cleaning, disinfecting, and monitoring the cleanliness of commercial and industrial plants or plant components and the use of an agent according to the present invention as an indicator solution for ascertaining the cleanliness of commercial and industrial plants or plant components by ascertaining the intensity of the light emitted in the violet wavelength range by the solution are described.

         58 . A process for the cleaning of an installation, comprising the steps of rinsing the installation with an alkaline cleaning solution, testing the result of the cleaning for compliance with a previously determined final cleaning result by using an indicator agent on the basis of permanganate in an alkaline environment, and subsequently introducing the indicator agent that is used as an indicator into the alkaline cleaning solution for further use as a cleaning agent in a subsequent cleaning step. 
     
     
         59 . A process in accordance with  claim 58 , and collecting the alkaline cleaning solution, after the cleaning run, in an alkaline solution container for reuse. 
     
     
         60 . A process in accordance with  claim 59 , and introducing the indicator agent used into the alkaline solution container. 
     
     
         61 . A process in accordance with  claim 58 , and rinsing the installation with at least one additional agent, and introducing the indicator agent into the installation after the last cleaning step. 
     
     
         62 . A process in accordance with  claim 58 , and introducing the indicator agent into the installation before a sterilization step. 
     
     
         63 . A process in accordance with  claim 58 , and determining a change brought about by the indicator agent by means of a monitoring device, and comparing that determined change with a theoretical value. 
     
     
         64 . A process in accordance with  claim 62 , wherein the monitoring device has a first and a second color value detector, whereby the first color value detector is positioned in front of the entrance of the indicator agent into the installation, and the second color value detector is positioned after the exit of the installation. 
     
     
         65 . A process in accordance with  claim 62 , wherein the change brought about is a change in color.
