Key benefits Safer, more efficient cleaning: Nylon brush head removes lint, soot and pellet build-up that restrict airflow and create overheating or fire risk. Durable and non-abrasive: Heat-resistant, anti-aging nylon bristles clean effectively without scratching or damaging the inner surface of chimneys, ducts and dryer tubes. Reach and flexibility: Interlocking rods can be connected to extend reach and flex through bends, so you can access deep or curved vents without forcing the brush. What it does Clears lint, ash, soot and pellet deposits from dryer tubes, chimneys, exhaust ducts and other pipes. Restores airflow to improve appliance performance and reduce drying times and energy use. Reduces the risk of overheating and fire by removing flammable accumulations. Key attributes Brush head material: nylon — heat resistant and long-lasting. Rods: connectable and flexible to navigate bends and extend working length; easy to assemble and disassemble for storage. Safe on interior surfaces: bristles clean without scratching metal or masonry interiors. Practical use scenarios Dryer vent maintenance: Run the brush through the dryer tube and exterior vent to remove lint build-up, improving drying efficiency and lowering fire risk. Chimney and fireplace flue cleaning: Use the flexible rods and nylon brush head to loosen soot and ash inside the flue before a professional inspection or annual maintenance. Pellet stove and exhaust duct cleaning: Remove pellet residue and exhaust deposits from stove vents and ductwork to maintain proper ventilation and safe operation. User notes Assemble rods to the length needed; disassemble for compact storage. Designed for repeated use thanks to heat-resistant, anti-aging nylon bristles. Compatible with common pipe, chimney and duct cleaning tasks where a non-scratching, flexible brush is required.
