The Permanent Press cycle is a washer or dryer cycle that can help remove or reduce wrinkles from clothes that can remain minimally wrinkled if washed and dried properly. Permanent press clothes are often made of synthetic fibers such as polyester or specially treated to guard against wrinkles. The Permanent Press cycle uses warm water and slower spin cycles to help release existing wrinkles while minimizing the creation of new wrinkles. The dryer cycle uses medium heat and an additional cool down period to help keep clothes from wrinkling or creasing. The Permanent Press cycle helps prevent wrinkles from setting in by using a longer cool down spray rinse along with a normal wash and spin speed in the washer. In the dryer, this cycle uses controlled heat at about 135° F and a post-cycle routine to help prevent wrinkles from setting in. The Permanent Press cycle is ideal for delicate fabrics such as rayon, nylon, spandex, and polyester, and heavily soiled items can benefit from the permanent press cycle due to its low-temperature setting, which is safer for fabric. The permanent press cycle should be used when clothes cannot be ironed or when the garment tag states ‘permanent press’ or ‘tumble dry’ .
