A method of treating oil contaminated cuttings comprising the steps of: contacting the oil contaminated cuttings with a detergent solution comprising a solvent and a surfactant selected from the group consisting of alcohol ethoxylates, phenol ethoxylates, alkylphenol ethoxylates, amine ethoxylates, thioethers, and combinations thereof so as to wash the oil from the cuttings and into the detergent solution; and separating the washed cuttings from the detergent solution containing the removed oil. The detergent solution containing the removed oil is optionally recycled back into the drilling mud.
