A.W. Perkins 9 Inch Round Wire Chimney Brush

For a brick or clay masonry flue, a steel wire brush is the correct material choice. Steel bristles are tough enough to remove creosote and soot from a masonry flue without degrading it, while poly brushes are generally reserved for metal venting systems. The A.W. Perkins 9 Inch Round Wire Chimney Brush is designed for use in brick chimneys and is the right diameter for your flue. Sizing guidance suggests using a brush as close to the flue dimensions as possible, rounding up to the next largest inch when the flue falls into an odd size bracket. Therefore, a 9-inch round wire brush is the correct pick for an 8.5-inch round flue. AW Perkins also manufactures this brush in sizes ranging from 6 to 10 inches if you require a different diameter.
