The permanent press cycle is a setting on washing machines and dryers that can help remove or reduce wrinkles on clothes. It is ideal for clothes that are prone to wrinkling, color-fading, shrinking, and stretching. The permanent press cycle on a washing machine washes clothes in warm water and rinses them in cool water, with mild agitation and spin cycles. On a dryer, the permanent press cycle uses medium heat and a cool-down period to keep clothes from wrinkling or creasing. The cool rinse at the end of the washing cycle and the lower heat setting of the dryer help prevent wrinkles from forming in the first place and help release ones that do form. The permanent press cycle is softer than the standard dryer cycle and is meant for clothes that can handle the washer and dryer cycles but still need some protection. It is ineffective at drying heavy denim and durable clothes but is ideal for keeping the wrinkles out of work blouses and date night dresses.
