When and How to Clean Your Dryer Vent Properly

We recommend cleaning your dryer vent every six to 12 months, depending on use. Add it to your list of annual home maintenance chores so it doesn’t get put on the back burner. You can have your vent professionally cleaned or use these DIY dryer vent cleaning instructions.

How to Clean Your Dryer Vent in 3 Easy Steps

Step #1: Clean the Lint Trap

Peel the lint off the lint trap and throw it away. If you’re not in the habit of doing this after every load of laundry, you should start now.

Next, hold the lint trap under running water. You may notice water pooling on the screen even though you can’t see any visible blockage. This is wax left behind by dryer sheets and fabric softeners.

Use warm soapy water and a soft brush to remove this residue. Rinse the trap well and make sure there’s no more pooling. Let the trap dry thoroughly before replacing it.


Step #2: Clean the Lint Trap Vent

While the lint trap is drying, use a long wire appliance brush to grab lint hiding in the lint trap vent or housing. You can bend the appliance brush in order to get into all the nooks and crannies. We recommend making several passes with the lint brush to ensure you’ve removed as much as possible.

Then, use a long, narrow vacuum hose attachment to suck away what the appliance brush may have left behind. If you clean your dryer vents every six to 12 months, this step won’t be as much of a hassle next time.

Step #3: Clean the Dryer Vent

On to the most important step to note when you need to learn how to clean your dryer vent: cleaning the dryer vent duct. Move the dryer away from the wall and disconnect the power. Give yourself plenty of room to scooch in there and move around. Disconnect the duct from the wall.

Grab your appliance brush again and get to work!

›For Foil or Plastic Ducts: If your dryer duct is plastic or foil, gently spin the brush inside the duct to remove the lint build up. Don’t be too forceful, as these flexible ducts could get damaged.
›For Metal Ducts: Metal dryer ducts can handle a bit more force. Attach an electric drill to the end of the brush to speed up the cleaning process.
