Dryer balls are a set of orb-shaped, reusable laundry products that are added to the dryer along with wet clothes to help prevent clothing from clumping and wrinkling, reduce drying time, and eliminate static cling. They work by separating the layers of fabric in the laundry and allowing hot air to circulate better throughout the clothing in the dryer. This can help reduce drying time and save on energy costs when taking on large loads of laundry. Dryer balls are typically made of wool, plastic, or rubber. Wool dryer balls are the most common and eco-friendly option, as they are reusable and do not contain any harsh chemicals that can break down and damage fabric over time. Plastic and rubber dryer balls are durable options and a better choice for those wanting to avoid the possible shedding of wool fibers and pilling that may result from wool dryer balls. Dryer balls can be safely used in both gas and electric dryers. To use dryer balls, simply toss them in the dryer with your wet washing, shut the dryer door, and start the drying cycle. The number of dryer balls to use depends on the size of the load, but typically 3-6 dryer balls are recommended.
