Do Laundry Efficiently
The laundry balls bounce around in the dryer separating clothes, allowing more hot air to circulate through all the garments. As they tumble, the wool balls fluff your laundry, reduce wrinkles, and basically pummel the laundry to make it softer.
For regular loads, use at least 3-4 balls to notice a decrease in drying time. For large loads, use 6 or more wool balls. The more dryer balls you have in a load, the shorter the drying time will be.
To completely eliminate static electricity buildup some tweaking is needed.
Just spray the dryer balls with a bit of water before throwing them into the dryer. Or you can also pin a safety pin into one of the dryer balls and let the metal diffuse the static.
