Extrusion dies may be cleaned, especially of so-called die drips, by pass ing a wire over the die orifices in the vicinity of the exit face of the ext rusion die. The operation of the extrusion operation is not affected by the passing of the wire through the stream(s) of the extrudate, and so the extru sion operation need not be shut down for the cleaning process. The process i s especially useful for cleaning dies through which polymers are extruded.</ SDOAB>
