It is important to clean the clogged dryer vent as quickly as possible as it poses a potential fire hazard. Steps to clean the vent: Access inside the dryer duct with a vacuum nozzle to remove the lint build-up. Use a stiff cleaning brush for the unreachable areas. You should use duct cleaning kits that can be attached to a cordless drill to remove lint from the vent. Dryer lint vents and ducts should be inspected and cleaned frequently to prevent clogs and to keep your laundry drying reliably.
