In addition to our hard chimney brushes, we also offer a range of extra hard brushes with black bristles. These brushes are specially developed for cleaning larger flues with stubborn tar and creosote deposits in masonry and pumice chimney systems. Thanks to their larger diameter and extra stiff bristles, these brushes provide a thorough and powerful cleaning result. Our extra hard brushes are handmade and available in various diameters, so you can always find the right brush for your specific application. All brushes are suitable for use with our 1/2″ Whitworth flexible liner rods (for flexible and insulated chimney systems) and our 3/4″ rigid rods for traditional masonry chimneys.
