For chimneys that need more than a single pass, this kit pairs two brush heads on one rod, combining soft nylon bristles for routine dusting with steel wire bristles for scrubbing stubborn creosote, so square, rectangular, and arched flues all get cleared in one trip. The nylon rod extends to 23 feet (7 meters) and bends past 90 degrees to follow bends in the flue instead of jamming, while a plastic swivel connector keeps your hands away from the rotating rod as you sweep from the bottom up. Rod sections click together with a spring-button lock that stays put whether turned clockwise or counterclockwise, so extra sections can be added without the joint working loose. Weighing 4.19 pounds (1.9 kg), the kit is easy to handle solo, and it comes with an extra brush and goggles so you can tackle heavier buildup and protect your eyes from falling debris.
