The present invention relates to a method for cleaning a spunbonding spinneret for the production of cellulosic spunbonded nonwoven fabric from a solution of cellulose in an aqueous organic solvent by extruding the solution through nozzle holes of the spunbonding spinneret to form filaments and stretching the filaments in the direction of extrusion by means of a gas stream, during which method contaminations containing cellulose will accumulate on the spinneret surface. The method according to the invention comprises the steps of: a) spraying the contamination with an aqueous fluid precipitating the cellulose; and b) detaching and carrying away the contamination by means of the gas stream.
