A permanent press wash is a washing machine cycle that uses a combination of warm water during the wash and cold water during the rinse. It is designed to reduce wrinkles from forming on clothes that are prone to wrinkling, color-fading, shrinking, and stretching. The permanent press cycle is a staple on washers and dryers, and it is a great way to protect clothes that are prone to wrinkling, color-fading, shrinking, and stretching. The cycle typically lasts around 30 minutes with gentler agitation compared to a normal or heavy-duty wash cycle. Additionally, 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 ideal for synthetic fabrics, including rayon, nylon, spandex, and polyester, and clothes that cannot be ironed. It is not recommended as a substitute for a delicate wash, and delicate clothes, thin "delicate" material, or bras should be washed on the delicate cycle. The permanent press cycle on your washer and dryer is a versatile option, providing a gentle wash or dry that protects clothing from shrinking, fading, and creases.
