description A down hole cleaning assembly and method of cleaning a tubular. Generally, the down hole assembly (2) is connected to a work string concentrically located within a casing string. In one embodiment, the down hole assembly (2) comprises a mandrel (16) operatively connected to the work string, with the mandrel (16) having an opening (22, 24) therein. A pad member (38, 40) is received within the opening (22, 24), with the pad member (38, 40) having a groove therein. Also provided is a wire brush member (42, 44), operatively positioned within the groove of the pad member (38, 40), for cleaning the internal diameter of the casing string. The pad member (38,40) and groove may be helical, the wir e brush member (42, 44) positioned within the groove. The down hole assembly (2) further comprises a biasing member (46, 48), operatively positioned between the mandrel (16) and the pad member (38, 40), adapted for biasing the wire brush means (42, 44) against the inne r diameter of the well bore.
