The permanent press washer setting is a cycle that can help remove or reduce wrinkles from clothes while minimizing the creation of new wrinkles. It uses 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. On a dryer, the permanent press cycle uses medium heat and an additional cool down period to help keep clothes from wrinkling or creasing. The permanent press cycle is ideal for clothes that wrinkle easily, including synthetic fabrics, rayon, nylon, spandex, and polyester. However, it is not recommended as a substitute for a delicate wash, and delicate clothes should be washed on the delicate cycle. It is important to sort clothing based on fabric, color, and care instructions and to properly match the washer settings to the laundry loads to stretch the lifespan of the clothes.
