Drying clothes indoors can be a cost-effective and energy-efficient alternative to using a tumble dryer. To maximize drying efficiency, hang clothes on a drying rack or clothesline near a window or in a well-ventilated room to take advantage of natural airflow and sunlight. Placing a dehumidifier or a fan in the room can also help speed up the drying process by reducing moisture levels in the air. Additionally, spreading clothes out evenly and turning them occasionally can ensure faster drying. Avoid hanging clothes in cramped or poorly ventilated spaces, as this can lead to a musty smell and prolonged drying times. With these tips, you can save money on your energy bills while keeping your clothes fresh and clean.
