The answer to 'DIY dryer vent cleaning' is that it is a recommended maintenance task that most homeowners can do themselves. Regularly cleaning your dryer vent helps prevent fire hazards, improve efficiency, and extend the life of your dryer.
To clean your dryer vent, start by unplugging the dryer and pulling it away from the wall. Use a dryer vent brush or a plumber's snake to dislodge any lint buildup in the vent hose. You can also use a vacuum hose attachment to suck up any loose lint. Be sure to clean the exterior vent opening as well to remove any obstructions. When finished, reconnect the dryer and check that the vent flap opens and closes properly.
