This brush, with a very flexible attached handle, is perfect for navigating the tight bends and elbows of a dryer vent or pellet stove pipe.
Because it is made of poly bristles it won’t scratch or damage vents like a wire brush would. Available in two different brush sizes and two different handle lengths. 4″ Pellet stove vent pipe cleaning kit; 4″ Brush with 20′ Flex Handle, by Rutland #17420
