How to Clean a Dryer Vent and Lint Trap (Prevent Fires)

A clogged dryer vent makes clothes take longer to dry, wastes energy and can be a fire hazard. Cleaning it regularly is one of the most important home safety tasks.

Clean the Lint Screen After Every Load

Pull out the lint screen and remove the lint by hand. This is the simplest way to keep your dryer working well.

Wash the Lint Screen Every Few Months

Dryer sheets can leave a film that blocks airflow. Wash the screen with warm water, dish soap and a soft brush. Let it dry completely before putting it back.

Test: Run water over the screen. If water pools instead of passing through, it needs washing.

Clean the Lint Trap Housing

With the screen removed, use a vacuum hose or a long, flexible lint brush to remove lint from inside the slot.

Clean the Dryer Vent

Do this at least once a year:

1. Unplug the dryer (or turn off the gas supply for gas dryers).
2. Carefully pull the dryer away from the wall.
3. Disconnect the vent hose from the back of the dryer.
4. Use a dryer vent cleaning brush kit to clean the hose and the duct in the wall.
5. Clean the exterior vent opening outside your home, making sure the flap opens freely.
6. Reconnect everything securely.

If your vent is long or hard to reach, consider hiring a professional.

Signs Your Vent Is Clogged

• Clothes take more than one cycle to dry.
• The dryer feels very hot on the outside.
• You notice a burning smell.
• The vent flap outside doesn't open when the dryer runs.
