A cleaning device for cleaning a coagulator has a housing defining an interior chamber with a prong extending along a central axis to receive a coagulator bore. An insertion guide with an opening along the central axis guides insertion of the tip of the coagulator onto the prong. Pliable wipers extend inward from the sidewalls of the chamber toward the prong, so that the wipers deform by contact to wipe against the coagulator in operation. The wipers can be formed as part of a pliable tubular member that is inserted into the chamber in the housing and held in place by an end cap that incorporates the insertion guide.
