How to Clean a Clothes Dryer Exhaust Duct

Keep your clothes dryer running safely and efficiently by cleaning the exhaust duct on a regular basis. Follow these steps to keep your dryer operating in top condition.


  • Step 1: Unplug the dryer; detach hose Unplug the dryer and use a screwdriver to detach the hose from the exhaust duct.
  • Step 2: Inspect and remove lint Inspect the hose and the aluminum elbow that attaches to the wall. Remove lint by feeding a vent brush through the dryer from inside the machine through the hose.
  • TIP: Cleaning out the dryer vent can be a dirty job. Wear a dust mask to keep from breathing dust and other particles that may be released.
  • Step 3: Vacuum behind dryer and around vent pipe Use an industrial vacuum to thoroughly clean the area behind your dryer, the back side of your dryer, and the area around the vent pipe.
  • Step 4: Clean soap scum from the floor Use a sponge and soap to clean up any scum that has built up on the floor behind your dryer.
  • TIP: Clean the lint filter after every load of laundry to keep your dryer operating smoothly.
  • Step 5: Reattach hose; plug dryer in Reattach the vent hose and secure it in place, and then plug in your dryer. Clean the exhaust duct at least once a year to keep it in peak operating condition.
  • FACT: Industrial designer Brooks Stevens created the first electric clothes dryer with a glass window in 1937.
