Abstract (en)

[origin: WO0158607A1] A method for cleaning surfaces made of concrete, asphalt or similar, especially airport runways, road surfaces, the floors of halls or similar. In order to clean and remove soiling substances, such as rubber, oil, fat, carbon particles or similar, which adhere to a surface, a cleaning agent resulting in the dissolution or detachment of said soiling substances is applied to the surface in question, whereupon a rinsing fluid, especially water, is subsequently used to rinse the surface and to remove the dissolved soiling substances therewith and collected in at least one collector. The cleaning which occurs is quick and devoid of any abrasive effect on a covering coat or wearing coat of the surface to be cleaned. The inventive cleaning agent is made of an aqueous emulsion, containing at least one upper methyl, ethyl, isopropyl carboxylate and at least one multivalent alcohol.
