To maintain the efficiency and safety of your dryer, it is recommended to clean the lint trap before or after every load of laundry. Cleaning the lint trap regularly helps prevent the buildup of lint, which can obstruct the airflow, reduce drying performance, and even pose a fire hazard. It only takes a few moments to remove the lint from the trap, so making it a habit to clean it with each use is a good practice. Additionally, it's essential to periodically check and clean the dryer vent and exhaust duct to ensure proper airflow and minimize the risk of lint accumulation.
