The answer to 'DIY dryer vent cleaning' is that it is recommended to clean your dryer vent at least once a year to maintain proper airflow and prevent fire hazards. Cleaning the vent yourself can be done with the right tools and safety precautions, but may require a professional if the vent is excessively clogged or difficult to access.
To clean the dryer vent yourself, first unplug the dryer and pull it away from the wall. Use a dryer vent cleaning brush or a plumber's snake to loosen and remove any lint buildup inside the vent. Vacuum up any loose debris, then use a vent brush to scrub the interior walls of the vent. Finally, use a vent brush attachment on your vacuum to suck up any remaining lint.
