What a Clogged Dryer Vent Looks Like
Watch for these signs:

Burning smell
Excess lint behind dryer
Outside vent flap doesn’t open properly
What You’ll Need
Keep it simple:
Vacuum cleaner with hose
Vent cleaning brush (long flexible)

Gloves and mask (recommended)
The Fix: Step-by-Step System
Step 1: Disconnect the Dryer
Unplug the dryer and move it slightly away from the wall.
Step 2: Remove the Vent Hose
Loosen the clamp
Gently pull the hose off
You’ll likely already see lint buildup here.
Step 3: Clean the Vent Hose
Insert the brush deep inside
Rotate and pull out lint
Use a vacuum to remove remaining debris
Step 4: Clean the Wall Duct
Push the brush into the wall vent
Go as deep as possible
Pull out lint and vacuum thoroughly
Step 5: Clean the Exterior Vent
Go outside and check the vent outlet:
Remove lint blocking the flap
Ensure it opens freely
Clear any debris or nests
Step 6: Reconnect Everything
Attach the hose securely
Tighten clamps
Move dryer back
Step 7: Test the Airflow
Run the dryer and check:
Strong air flow outside
Faster drying time
No overheating
Common Mistakes to Avoid
Only cleaning the lint filter (not enough)
Ignoring the outside vent
Crushing the hose behind the dryer
Using long, twisted vent pipes
What Causes Dryer Vent Clogs?
Lint buildup over time
Poor-quality vent hoses
Long or curved duct systems
No regular maintenance
How to Prevent Future Clogs
Clean lint filter after every load
Deep clean vent every 2–3 months
Use rigid or semi-rigid metal ducts
