The invention relates to a cleaning, disinfection and indicator agent, comprising a water-soluble permanganate, in particular, for mixing with an agent, guaranteeing an alkaline medium with a pH value of at least 11 and a further oxidising agent, in addition to the water-soluble permanganate, the oxidation potential of which lies above that for manganese VII to manganese VI, pH-buffer substances, preferably primary and/or secondary alkali carbonates such as sodium carbonate and/or sodium bicarbonate and oxidation-resistant polyphosphates. The invention further relates to methods for cleaning, disinfecting and monitoring the purity of commercial and industrial plants, or plant components and the application of such an agent as indicator solution, for determining the purity of commercial and industrial plants, or plant components, by means of recording the intensity of light emitted by the solution in the violet wavelength range. |
