PROBLEM TO BE SOLVED: To provide a method and device for removing a residual dross capable of satisfactorily removing a flux residual dross in a short period of time. SOLUTION: A heating part 13 for spurting a gas to the flux residual dross 20 so as to be able to heat the surface of the flux residual dross 20 is arranged. The flux residual dross 20 is melted by heating the flux residual dross 20 with the use of the heating part 13 so that the temperature of the surface of it exceeds 250°C, and the melted flux residual dross 20 is flowed by the gas.
