There are clear rules when it comes to doing laundry. Colors are separated, delicate fabrics are washed gently, and detergent is dosed appropriately. However, opinions differ on one question: Should you shake out laundry before hanging it up?
Some people vigorously shake out fresh laundry, while others prefer to hang shirts, T-shirts, and pants directly. This extra step can indeed affect how smooth the clothes come off the line later. myHOMEBOOK spoke with the German Cosmetic, Toiletry, Perfumery and Detergent Association (IKW) to find out what role shaking out plays in achieving wrinkle-free laundry.

What is the Purpose of Shaking Out?
Shaking out freshly washed laundry is generally recommended. Dr. Bernd Glassl from the German Cosmetic, Toiletry, Perfumery and Detergent Association (IKW) explains that shaking out helps smooth some wrinkles. Textiles made of cotton or linen can also be gently pulled smooth. The sleeves of shirts and blouses can be shaped this way, according to Glassl. However, caution is advised with woolen garments. Wool textiles should not be shaken out but merely adjusted slightly, the expert recommends.

What Else to Consider for Wrinkle-Free Laundry
To avoid wrinkles, there are several things to consider even during washing. The right settings are crucial. “The higher the spin speed and the fuller the washing machine, the more wrinkled the textiles will be, but the lower the residual water content,” explains Dr. Bernd Glassl. Since some textiles are washed at high speeds, you should at least ensure that the washing machine is emptied promptly after the wash cycle. “The longer the textiles remain crumpled in the machine, possibly even drying, the more stubborn the wrinkles become,” the expert says.
When drying laundry, there are also some points to consider to avoid wrinkles. After shaking out and smoothing, it’s best to hang tops like shirts, blouses, or T-shirts on a hanger. A little space between individual textiles also makes drying easier. If you have the opportunity to dry your clothes outdoors, you should take advantage of it. Especially when it’s a bit windy outside, it can positively affect potential wrinkles. Another advantage: Drying outdoors also preserves the fibers and saves energy costs.
