To clean a dryer vent from the outside, start by locating the vent cover on the exterior wall. Remove the cover if possible, then use a vent brush or vacuum attachment to clear out any lint or debris blocking the vent. Work carefully to remove as much buildup as possible. You may also use a leaf blower to push lint out from inside the dryer if accessible. Routine cleaning helps prevent fire hazards and improves dryer efficiency.
