PROBLEM TO BE SOLVED: To provide a method for cleaning an organic contaminant capable of cleaning in a shorter time at a low cost by performing cleaning and solidifying in a single kneading stage with in-situ cleaning as the premise. SOLUTION: Regarding the method for cleaning an organic contaminant, when a contaminant contaminated with an organic pollutant is subjected to in-situ cleaning using a kneading machine provided with a stirring blade interpenetrated into the contaminant and further drawn from the contaminant, a cleaning agent and a solidifying material (such as an iron based catalyst, an oxidizer and a neutral solidifying material) are added to the contaminant in an once interpenetrating-drawing step of the stirring blade, so as to perform kneading.
