Tennis balls used as a laundry hack for bulky fabrics

Cleaning experts suggest using tennis balls in the washing machine to improve the care of bulky items like duvets and down jackets. The balls work by gently hitting the fabrics during the cycle, which aerates the fibers and prevents them from clumping together or sticking.

According to Maribel Mendoza, adding two clean tennis balls can significantly accelerate the drying process by allowing better air circulation between garments. Additionally, this method helps maintain fluffiness, prevents fibers from tightening, and can assist in collecting pet hair that often accumulates in the drum.
