How to Clean Dryer Lint Trap Deep Clean
Even if you clean your lint trap after every load, fabric softener and dryer sheet residue gradually coat the screen mesh, invisibly reducing airflow and forcing your dryer to work harder. This deeper maintenance goes beyond the after-load cleaning to actually wash the lint screen with soap and water and vacuum out the housing slot where lint accumulates below the screen. This quarterly deep clean reduces fire risk, improves drying efficiency, and helps your dryer last longer.

Why It Matters
Even when you clean lint after every load, fabric softener residue coats the screen and reduces airflow. A dryer working harder uses more energy and poses a greater fire risk. Deep clean quarterly. Do the water test: run water over the screen—if it pools instead of flowing through, wash with soap and a brush. If your dryer takes longer than usual to dry clothes, this maintenance might be overdue.
Safety First
- Unplug the dryer before reaching into the lint trap housing
- Lint is highly flammable - do not use near open flames

Step-by-Step Instructions
Before You Start
This is a deeper clean than the after-every-load lint removal. You are cleaning the screen itself and the housing it sits in.
- 1
Remove the lint screen from the dryer
- 2
Run water over the screen - if water pools instead of flowing through, the screen needs washing
Fabric softener and dryer sheet residue invisibly coats the screen over time
- 3
Scrub the screen with warm soapy water and a soft brush
- 4
Rinse thoroughly and let it dry completely before reinstalling
- 5
Use a vacuum crevice tool or lint trap brush to clean inside the housing slot
- 6
How to Verify Success
Water flows freely through the lint screen. No lint visible in the housing. Dryer heats efficiently and clothes dry in normal time.
When to Call a Professional
- Clothes take much longer than normal to dry (vent cleaning $100-200, heating element $150-300)
- Dryer is overheating (thermostat replacement $100-200)
- You smell burning when the dryer runs (immediate inspection needed, service $100-200)
