An apparatus that employs a pair of high peripheral speed impact cutters to remove hard carbonaceous deposits from the lateral surfaces of the refractory lining of coke oven doors. The motion of these cutters is synchronized with that of an element of the apparatus which displaces it from one position to another on the door, and, in one embodiment, means are also provided to scrape tarry carbonaceous deposits from the door's seal ring.
