Process for cleaning and degreasing comprising treatment with a tenside and electrolyte containing water solution. The solution is prepared at the site of use by the mixing of a water free or nearly water free (below 20 weight %) premix, containing one or more nonionic tensides and one or more tensides with charge giving function of which at least part (25 to 100 weight %) has hydrotrope properties and eventually electrolyte in solution or in the shape of solid state, dispersed, finely divided particles, with water and, if the premix does not contain electrolyte, solid state electrolyte, liquid electrolyte or electrolyte solution at the site of use. The invention also concerns a spontaneously dispersing composition intended for use at the process, the resulting tenside/electrolyte mixture and its use. |
