Disclosed is a method for decontaminating PCB-containing transformers to obtain treated transformers containing less than 50 parts per million (ppm) polychlorinated biphenyls (PCB). The transformer is initially drained of all PCBs, then the core/coil assembly is removed. The internal surfaces of the transformer are then cleaned using a solvent. Finally, a new core/coil assembly is installed. The method is simple and can be completed within a substantially shorter period of time than methods known in the art.
