Durable nylon brush head for safe, effective cleaning Brush head: high-temperature resistant nylon that resists aging and stays flexible during use. Designed to remove debris without scratching the inner surfaces of chimneys, vents, or pipes. Performance: Aggressively dislodges lint, pellet residue, soot and dust to restore airflow and cleaning efficiency while minimizing damage to ducts and liners. Safety benefit: Regular use clears flammable lint and pellet build-up, helping reduce dryer overheating and chimney or stove fire risk. Easy to assemble, extend, and use Modular rod system: Connect multiple rods to extend reach into long vents, chimneys, and ducts. Rods assemble and disassemble quickly for storage and transport. Flexible design: Rods bend and flex to pass through common chimney and duct turns so the brush reaches deeper blockages that stiff tools cannot. Simple operation: Attach the nylon brush head to the rod system, push and pull through the run to break up and sweep out deposits. Compatible cleaning for many applications Suitable for: dryer vents and tubes, fireplace and chimney interiors, pellet stove pipes, exhaust ducts and other pipe runs where lint, ash, soot or dust accumulate. Size and fit: Modular rods allow you to build the length you need for most residential ducts and chimneys. The flexible connection is intended to navigate typical bends and offsets found in household venting. Practical use scenarios Dryer vent maintenance: Use the brush to remove lint from the dryer tube and vent outlet to improve drying performance, reduce runtime, and lower the risk of dryer fires. Chimney and pellet stove cleaning: Sweep soot, ash and pellet residue from pipe sections and flues to maintain draft, reduce odor, and limit creosote/pellet build-up. Exhaust duct clearing: Clean kitchen and bathroom exhaust ducts or other ventilation runs to restore airflow and reduce dust accumulation. Why customers choose this brush Reliable material and construction for repeated use in high-temperature applications. Modular and flexible for reach and accessibility without forcing or damaging vent components. Focused on performance and safety: clears hazardous build-up and helps maintain appliance efficiency. Care and maintenance Rinse and dry the brush head after heavy soiling to prolong life. Inspect rods and connections for wear before use and replace components if they show significant damage.
