Abstract: A method for cleaning a ventilation system of a clothes dryer includes operatively connecting an open proximal end of a hollow duct cleaning tool to a portable airstream appliance adapted for generating a pressurized airflow. A lint screen is first removed from a screen housing opening at the lint exhaust of the clothes dryer. An open distal end of the hollow duct cleaning tool is then placed over the screen housing opening of the clothes dryer, such that the distal end closely engages the clothes dryer to operatively air-seal the screen housing opening. The portable airstream appliance is then activated to direct the pressurized airflow through the duct cleaning tool, lint exhaust and ventilation system of the clothes dryer, thereby evacuating lint and debris collected inside the ductwork of the ventilation system.
