How to Safely Clear a Clogged Dryer Vent

Dryer lint is a silent fire hazard that accumulates slowly over months of laundry cycles. When your clothes take two sessions to dry or the machine feels unusually hot to the touch, your vent system is likely restricted and crying out for a deep clean. Performing this task yourself is straightforward, but it requires thoroughness. A clean vent ensures your dryer runs efficiently, saves on utility costs, and significantly reduces the risk of home fires. Treat this as a necessary seasonal ritual to keep your home's air flowing safely.

1. Unplug and Pull Back. Pull the dryer far enough away from the wall to access the vent hose. Unplug the unit from the power source and detach the ducting from the back of the machine.
2. Access the Outside Opening. Go outside and remove the exterior vent cover or hood. Use a screwdriver to loosen any fasteners so you have a clear path into the duct from the outside.
3. Brush Through the Duct. Assemble the flexible vent cleaning rod and attach the brush head. Insert the brush into the exterior vent opening and push it through the duct while rotating clockwise, working inward toward the dryer's location.
4. Extract Loosened Lint. Use a shop vacuum to pull out the lint you pushed toward the interior opening. Repeat the brushing and vacuuming process until no more lint pulls loose.
5. Replace with Metal Duct. Inspect the flexible hose that connects the dryer to the wall. If it is made of plastic or thin foil, replace it with a rigid or semi-rigid metal duct, as these are safer and less prone to clogging.
6. Verify Strong Airflow. Reattach the transition hose to the wall and dryer, securing all joints with foil tape. Plug the dryer in and run it on an 'air fluff' or low-heat cycle for 10 minutes to clear any remaining loose dust.
