A blend of aliphatic hydrocarbons and polyglycol ether(s) is used in a process for cleaning railroad tank cars that have been gravity drained of hydrocarbon fluids but may be left with a residuum containing heavy hydrocarbons, paraffin and noxious gas. A simple recirculation system is established between the chemical source, the contaminated railcar, canister filters and back to the chemical source. Contaminates are removed from the cleaning chemical by the filters and there is no water or steam used which might otherwise damage the railcar.
