Dryer balls are small, round objects made from materials like wool or plastic, designed to be used in a clothes dryer. They work by bouncing around with the laundry, helping to separate the items and allowing hot air to circulate more effectively. This can lead to faster drying times and reduced wrinkles in clothes. Using dryer balls can also help reduce static cling, making them a popular alternative to traditional fabric softeners. They are reusable and eco-friendly, as they can last for hundreds of loads, making them a cost-effective choice for maintaining laundry freshness.
