Choosing the correct chimney brush?
Our range of brushes are sized to suit the flue they are cleaning, for example a 6? internal diameter pipe will require a 6? brush. When opting for the right brush we recommend using a soft bristle for the smaller diameter pipes and increasing the brush bristle strength as the brush becomes larger. For flexible liner 5? or 6? diameter with soft fluffy soot a soft brush is adequate, for heavy soot we recommend opting for a medium bristle.
