ABSTRACT:
The invention relates to a concentrate for the effective, environmentally friendly treatment of oil-polluted stretches of ground and the cleaning of oil-contaminated surfaces, said concentrate containing an emulsifier, a vegetable oil and ethanol. The emulsifier is preferably a non-ionic surfactant with an HLB value between 7 and 8. The vegetable oil is preferably selected so that it is liquid at temperatures above 5 DEG C. Oils containing unsaturated fatty acids, in particular germ oils are especially suitable. For its application as a treatment for stretches of ground, the inventive concentrate is diluted with water to form a cleaning solution and is applied to the oil-contaminated surface that is to be treated. The oil is emulsified in the inventive cleaning solution and is detached from the particles of the ground. The oil degrades in a significantly easier manner in the emulsified state. To clean oil-contaminated surfaces, the cleaning solution is sprayed onto the latter. In an advantageous embodiment of the inventive cleaning method, a powder-like adsorption agent is added to the oil emulsion that is formed during the cleaning of oil-tank interiors, said agent adsorbing the emulsified oil and forming a sediment with the latter.
