An apparatus for scraping a lip of an extrusion die includes a scraping surface pressed against the lip. The scraping surface is movable along the lip of the die to clean debris, such as hardened thermoplastic, from the surface of the lip. The scraping surface may be removable and/or replaceable. A method of cleaning the extrusion die includes pressing the scraping surface against the lip of the extrusion die and traversing the scraping surface along the lip in a controlled manner.
