How can I safely and effectively clean my dryer vent from outside?

To safely and effectively clean your dryer vent from outside, start by disconnecting the vent from the dryer. Use a vent cleaning brush or a vacuum with a long attachment to remove lint and debris. Make sure to wear gloves and a mask to protect yourself from dust and allergens. Reconnect the vent securely once it's clean. Regularly cleaning your dryer vent can prevent fires and improve the efficiency of your dryer.
