Insider tip for pillows and down jackets
However, tennis balls can be used not only for soft towels, but also for washing pillows, down jackets or clothes that are particularly prone to wrinkles. Especially in textiles with filling, tennis balls can loosen up the contents and prevent them from clumping together during washing.
The balls also ensure that clothes and air circulate more evenly in the machines during the washing and drying cycle, which means that the laundry gets fewer wrinkles and can dry faster.
