The Permanent Press cycle is designed to help release existing wrinkles from clothes and prevent new wrinkles from forming. This cycle is particularly beneficial for items that are prone to wrinkling, such as dresses or professional wear. Depending on the make and model of your laundry machine, settings that are similar to the Permanent Press cycle may be labeled under a different name, such as the Wrinkle Control cycle available on select Maytag washers.
