No dust allowed: Your guide to dryer vent cleaning

Lint and dust shoot out from a pipe at the roof of a red house

For many, cleaning your dryer means tapping out the lint screen before or after each cycle. Did you know your dryer has a vent that needs to be cleaned, too? Let us be your guide, helping you keep your dryer vent lint free and clear.

What does a dryer vent do?

Much like what you’d guess, your dryer vent is the duct system that serves as the escape route for the moisture, heat, and lint coming from your machine’s drying cycle. The release of these three products during or shortly after drying clothes reduces the risk of mold growth, carbon monoxide exposure, and fire hazards. 

Indoor dryer vents

To check for an indoor dryer vent, look for yours to be hooked up to one of the following ducts or vents:

  • Vinyl or plastic vent: More common in older systems
  • Aluminum foil duct: Widely available; cost effective
  • Rigid metal duct: Best airflow
  • Semi-rigid duct: Better airflow than aluminum foil duct, but still flexible
  • Periscope vent: Slim; great for dryers in small spaces

Pro Tip: Vinyl vents are no longer recommended, as they are now a fire risk. If you’re in the market for a new one, consider upgrading to one of the other types available.

Outdoor dryer vents

Your outdoor dryer vent should be attached to one of your home’s exterior walls, and they’re usually come in one of the following forms:

  • As an open vent
  • With (often adjustable) vent flaps
  • With a cage cover

Cleaning your dryer vent

Now that you’ve located your dryer vents, it’s time to make them look like new! How often are you supposed to clean your dryer vent? To remove blockages and help prevent dryer fires, clear out your dryer vent at least once a year (more often if your household has a high laundry volume or frequency).

  4. Clean out your lint screen, for good measure.
  5. Put everything back in place, and you’re ready to clean your outdoor dryer vent!

  3. Use your vacuum’s crevice tool again to suck up anything hiding in your duct. 
  4. Replace any parts your removed.
  5. Reconnect the dryer, and run it empty for 20 minutes to push out any remaining debris.
  6. Enjoy warm, clean clothes and a more efficient machine!

Pro Tip: If cleaning your dryer vent(s) looks like too big or tricky of a task, call a trusted professional.   

Being delicate with your dryer

Now that your dryer vent is all clear, keep these four factors in mind to help your machine run better for longer!

Exercise load limits

When loading your dryer (or your washer), leave room for clothes to move around the drum as it rotates. An overfull load run twice won’t be as clean or as dry as two regular loads run once. 

Build in breaks

Even on laundry day, giving your washer and dryer 20 minutes in between loads can prevent your dryer from overheating or being overworked, helping you stave off costly repairs. 

Machine dry only certain materials 

Clothing that is not designed for the dryer can really damage it over time. Avoid machine drying garments with embroidery, sequins, or glued-on appliqué. 

Not only can this type of clothing become damaged during a tumble in the dryer, but pieces can also come loose and ruin other clothes or the machine itself. These and leather items are best cared for by air drying them in a space with good ventilation, away from direct sunlight. 

Pre-remove pet hair

Not everything comes out in the wash. By lint rolling your clothing before running it through your washer and dryer, you reduce the chances of it accumulating in your dryer and causing a blockage or fire. 

With this guide in your back pocket, you can help your dryer stay free of dirt and debris for years to come!
