Imagine a big load of wet bath towels going into the dryer. You hit “start” and that massive wad of wet fabric will flop around and stick together for quite a while until the layers become dry enough to separate and allow warm air to circulate. That slows the drying time, wasting time and energy.
Now imagine six wool dryer balls bouncing around (I use my entire set of six in every load), working their way between the layers of fabric, separating them so the warm air can circulate efficiently from the very start of the cycle. I’ve tested drying times with and without wool dryer balls, and the results are quite amazing. Wool dryer balls cut at least 25% off the time to dry a load of laundry, saving time and energy. I have also found these balls stuck tightly in the long sleeve of a tee-shirt and the pocket of a pair of jeans! They work their way into tight spaces and that’s what makes them so awesome.
Because dryer balls also agitate against the fibers in clothes and linens, everything feels softer coming out of the dryer. And used properly (coming up), they also take care of static cling.
