How To Clean A Dryer Duct – Steps

Cleaning a dryer duct on the inside is best done with the addition of a vacuum so you can control the lint dust.

Many dryer duct kits come with a special cap that allows you to attach a vacuum hose as well as run the flexible rod through the cap.

How To Clean A Dryer Duct


1.  Determine if it is easier to clean the dryer duct from the inside of the house or from the outside.  If the duct is on a second or third story you may want to clean it from the inside.

These caps fit into the dryer duct and prevent the lint dust from entering the room.

TIP:  Unplug the dryer from the power source and pull it out from the wall and the dryer duct connection.  Use care with gas connections.

2.  For best control attache one flexible rod to the drill and set your drill to spin clockwise.  Also set the drill clutch for a middle setting.  Slowly turn on the drill and move the brush in all the way and out allowing lint to come back towards your direction and into the vacuum or if not using a vacuum out of the pipe.
3.  Continue to add flexible rods until you have reached the end of your pipe.
TIP:  Use electrical tape to “tape over” the tread-ed rod connections to prevent any accidental detachment of the rods inside the dryer duct pipe.

4.   If you are cleaning the dryer duck from the outside remove

the dryer hood if possible.  If not possible use a paper clip to hold open the flapper.

TIP:  When done cleaning the entire dryer duct turn on the dryer and allow all of the loose lint debris to exit the pipe.  Run the brush through the pipe once or twice with the dryer running.  Wear a dust mask!

5.  After cleaning the duct work re install the dryer to the duct or the dryer hood to the pipe.  Replace and repair any damaged or worn parts.

2.  Vacuum all loose and visible lint from the machine.
3.  Locate the hood where the “squirrel cage” blower fan is and remove it.  This part usually has 2 or 3 screws holding it on.TIP:  Sometimes you need to remove the lint screen prior to disassembling this part.

Clearing Dryer Duct Obstructions

Reconnect everything and test dryer.  It is normal to see visible lint flying out of the exterior hood after doing this procedure.

Sometimes a dryer duct develops an obstruction whether it is from a rodent or a bird nesting inside the pipe.  Most dryer duct kits come with an obstruction attachment that replaces the brush.

The Blockage Removal Tool can be used to dislodge and clear animal and bird nests in the exhaust vent prior to rotary brushing and also clears debris from clogged gutter downspouts – without stepping foot on a ladder.
