Porcupine smoke chamber brush. Spin with an (8752) ButtonLok 2' long rod. Use with large ButtonLok Drill Adapter (2258, 2259 or 2258EZ or 2259EZ).
To use work from the top course of the smoke chamber and move brush on that course back and forth across the corbeled course. Brush works on both the vertical and horizontal surfaces. Reverse drill to make it easy to walk back across the face to the other side and get that end of things cleaned up. Step down a course or two at a time, don't move rod up and down as that can damage bristle attachment. Work back and forth until you reach the lowest course.
So much easier than hand scrubbing! Yellow bristle version here is gentler but perhaps more thorough. The black bristle version (6735) is more aggressive for removing harder debris.
