Lint buildup can restrict airflow and contribute to dryer fires. Drawing on U.S. Fire Administration and fire-safety guidance, this article separates routine user cleaning from professional duct and internal servicing. Filter locations and cleaning methods vary by dryer, so follow the model's manual first. The photograph depicts a strip of removed dryer lint, not a filter or a cleaning demonstration.

1. Wait until the dryer has fully stopped and is safe to touch, then locate and remove the lint screen as the manufacturer's manual describes. Never reach into moving or powered internal components.
2. Gently peel lint from the filter after every load. Do not improvise washing, brushes or chemicals unless the manufacturer's instructions permit them. Stop using the dryer if the filter is damaged.
3. Reinstall the filter securely before the next cycle. Do not run a dryer without its lint screen or with a blocked one. Keep lint and flammable clutter away from the machine.
4. Stop using the dryer if cycles suddenly take longer, laundry remains wet, the cabinet feels unusually hot or there is a burning smell. If there is smoke or fire, evacuate and call local emergency services.
5. For vented dryers, check that the outside exhaust outlet is not obstructed; have internal duct cleaning or disassembly handled according to the manual or by a qualified technician. Ventless heat-pump dryers use different filter and heat-exchanger care schedules.
6. Do not leave the dryer running while asleep or away from home. Review the manufacturer's inspection intervals, and contact a qualified service provider for recurring airflow trouble or unusual noises.
