The answer to 'how to clean dryer vent' is to regularly clean and maintain your dryer vent to prevent fire hazards and improve efficiency. A clogged or dirty dryer vent can cause your dryer to work harder, increasing energy costs and potentially leading to a fire.
To clean your dryer vent, start by unplugging the dryer and disconnecting the vent from the back of the appliance. Use a dryer vent brush or a vacuum hose attachment to remove any lint or debris that has built up inside the vent. You can also use a leaf blower to force air through the vent and push out any blockages. Once the vent is clear, reattach it to the dryer and check that the airflow is unobstructed.
