Deep clean the dryer lint screen when water no longer flows through it easily, when lint sticks after normal cleaning, or when drying takes longer even with the screen cleared. Clean the lint off every load, then wash buildup off the screen when it starts acting clogged.
Quick check
- Remove loose lint from the screen.
- Run water over the mesh.
- If water beads up instead of passing through, wash the screen.
- If drying is still slow after cleaning the screen, check the exterior vent and duct.
Why a lint screen can still be dirty
Fabric softener, dryer sheet residue, dust, pet hair, and fine lint can coat the mesh. The screen may look mostly clean while still restricting airflow. Restricted airflow makes the dryer work harder and can leave clothes damp at the end of a normal cycle.
How to deep clean it
- Pull the lint screen out and remove loose lint by hand.
- Rinse both sides with warm water.
- Use mild dish soap and a soft brush to clean the mesh.
- Rinse until water passes through the screen easily.
- Dry the screen completely before putting it back.
Don't damage the mesh. A torn lint screen should be replaced, not patched.
What this doesn't fix
A clean lint screen won't fix a crushed vent hose, a blocked wall duct, or a stuck exterior flap. If the dryer is hot, clothes are still damp, or the laundry room feels humid, the vent path needs attention.
Good maintenance rhythm
- Every load: clear lint from the screen.
- Every few months: wash the screen if buildup is visible or water beads on the mesh.
- Any time drying slows: check the exterior vent while the dryer runs.
