Abstract (en)
[origin: EP0305827A1] The invention relates to a process for the cleaning of hard material surfaces by treatment with ultrasound in wetting aqueous surfactant-containing baths. An important point here is that, to speed up the detachment of soiling and/or to eliminate contaminants which cannot be detached, or only incompletely, at least before a final stage of acoustic irradiation, the surfaces to be cleaned are wetted so intensively with a surfactant-containing liquid phase that the residual air adhering in microdispersed distribution to the micro-structure of the surfaces and the soiled areas is dispelled, at least to a great extent.
