How to Safely Clean Your Dryer Vent

Dryer vents are the quietest fire hazards in a home. Over time, fine lint bypasses the trap filter, building up inside the flexible duct and eventually creating a dense, flammable plug that forces your dryer to work significantly harder than necessary. Cleaning the vent line once a year is a simple maintenance habit that preserves the life of your appliance and prevents house fires. When done well, you will notice clothes drying in a single cycle rather than two, which confirms that the airflow path is clear and functioning at peak efficiency.

1. Kill the Power First. Unplug the dryer from the electrical outlet or shut off the gas supply valve if applicable. Carefully pull the machine away from the wall to expose the connection point between the dryer and the wall vent.
2. Free the Flexible Hose. Loosen the worm-gear clamps at both ends of the flexible hose. Gently twist and pull the hose free from the wall duct and the dryer exhaust port.
3. Vacuum the Port First. Use a shop vacuum to suck out any visible lint from the exhaust port on the back of the dryer. Do not push tools deep into the machine's internal fan housing.
4. Drill the Brush Faster. Insert a dryer vent cleaning brush into the wall duct opening. Work the brush in and out while rotating it to break loose stubborn lint buildup along the interior walls.
5. Pull All Debris Out. Insert the vacuum hose into the wall duct to extract all the lint loosened by the brush. Ensure you reach as far as the hose allows into the wall cavity.
6. Seal and Test Everything. Reattach the flexible hose to the dryer and wall, ensuring the connections are airtight and secured with clamps. Push the dryer back into position and run it on an air-dry cycle for 10 minutes to blow out any remaining dust.
