Step 2 · Clean Dryer Vent Duct
Insert the dryer vent cleaning brush into the ductwork from either the dryer end or the wall outlet end. Extend the brush as far as possible into the vent. Rotate the brush manually or with a drill (if using a powered kit) to dislodge lint from the duct walls. Simultaneously, use a vacuum cleaner with a hose attachment to suck out the loosened lint as you work the brush through the duct. Repeat this process for the entire length of the vent, working from both ends if necessary to ensure all sections are cleaned.
