The permanent press cycle is a setting on washing machines and dryers that can help remove or reduce wrinkles from clothes that are prone to wrinkling, color-fading, shrinking, and stretching. The cycle uses a combination of warm water during the wash and cold water during the rinse, with gentler agitation compared to a normal or heavy-duty wash cycle. The final spin cycle is slower, which helps to keep the weight of the wet clothes from pressing onto each other, largely reducing the chance of wrinkles. The permanent press cycle is typically used for synthetic fabrics, including rayon, nylon, spandex, and polyester, and clothes that cannot be ironed. The cycle is not recommended as a substitute for a delicate wash, and delicate clothing items should be washed on the delicate cycle, which uses light agitation to prevent damage to the fabric.
