Clean Dryer Vent & Exhaust Duct

LaundryLaundry RoomSeasonalEvery 6 months

Remove accumulated lint from the dryer hose and exterior vent duct to prevent household fire hazards and improve drying efficiency.

Supplies You'll Need

Always unplug electric dryers or turn off gas supply before pulling the unit away from the wall!
Do not use plastic accordion ducting — replace it with heavy-duty semi-rigid metal ducting if needed.

Unplug the dryer power cord (or shut gas valve) and gently slide the dryer out from the wall.
Disconnect the flexible duct hose from the back of the dryer using a screwdriver.
Use a vacuum hose attachment to clear out lint deep inside the dryer exhaust trap.
Attach the flexible duct brush to a drill or handle and snake it into the wall duct, rotating to knock free caked-on lint.
Go outside to the exterior exhaust vent cover, clear any lint clogging the louvers, and vacuum out the outer pipe.
Reattach the duct to the dryer securely using UL-listed foil tape (do not use standard duct tape).
Slide the dryer back into place, plug it in, and run on Air Fluff for 5 minutes to clear remaining loose dust.

Do this chore twice a year (Spring & Fall) to cut electricity usage by up to 30%.
Check the exterior hood flap while the dryer is running to make sure air flows freely.
