Cleaning the lint screen before or after each dryer cycle is a good habit—but it’s only part of the equation. Your dryer vent also needs regular attention to keep things running safely and efficiently. Here’s everything you need to know about keeping your dryer vent clear and your laundry routine worry-free.

What Does a Dryer Vent Actually Do?

Your dryer vent is responsible for releasing heat, moisture, and lint from your dryer to the outside of your home. Without it, those byproducts could build up indoors, leading to mold, carbon monoxide exposure, or even fire hazards. That’s why keeping the vent clean and clear is a key part of home maintenance.

Indoor Dryer Vents: What to Look For

Indoor dryer vents are typically attached to one of the following duct types:

  • Vinyl or plastic – Found in older setups but no longer recommended due to fire risk
  • Aluminum foil duct – Flexible and affordable
  • Rigid metal duct – Offers the best airflow
  • Semi-rigid duct – A good balance of flexibility and performance
  • Periscope vent – Ideal for tight laundry spaces

Pro tip: If your system still uses a vinyl vent, consider upgrading to a safer, fire-resistant alternative.

Outdoor Dryer Vents: Spot the Setup

Outdoor vents are usually installed on the exterior wall of your home. They may look like:

  • An open vent
  • A vent with adjustable flaps
  • A vent with a cage or screen cover

Each style needs regular clearing to ensure lint doesn’t build up over time.

How (and When) to Clean Your Dryer Vent

You should clean your dryer vent at least once a year—more often if you have a large household or do laundry frequently.

Indoor Dryer Vent Cleaning Steps:

  1. Unplug your dryer.
  2. Use a vacuum crevice tool to remove lint or debris from the duct. Gently tap to loosen buildup.
  3. Vacuum the vent cap where the duct connects to your home.
  4. Clean the lint screen for extra measure.
  5. Reconnect everything and prep to clean the outdoor vent.

Outdoor Dryer Vent Cleaning Steps:

  1. Use a dryer brush to remove visible lint.
  2. If needed, remove the vent cover—bugs sometimes like to hide here.
  3. Vacuum inside the duct with your crevice tool.
  4. Replace any removed parts.
  5. Run the dryer empty for 20 minutes to flush out lingering debris.

Pro tip: If this process feels overwhelming, you can always hire a professional for help.

Dryer Longevity Tips: Keep Your Machine in Top Shape

Now that your vent is clean, make the most of it with these smart habits:

  1. Don’t overload – Leave room for clothes to tumble freely.
  2. Let it rest – Wait about 20 minutes between loads to prevent overheating.
  3. Avoid drying delicate items – Skip machine drying anything with embroidery, sequins, or glued-on decorations.
  4. Remove pet hair beforehand – Lint-roll clothes before washing to reduce buildup in your dryer.

With a little seasonal upkeep, you’ll keep your dryer running smoothly—and your laundry routine safer and more efficient.
