Ironing is the process of using a heated tool, called an iron, to remove wrinkles and creases from fabric. The heat from the iron relaxes the fibers in the material, allowing them to be flattened out. This is commonly done on clothing, such as shirts and pants, to give them a neat and polished appearance. To iron effectively, the fabric is usually placed on a flat surface known as an ironing board. A spray bottle with water may be used to dampen the fabric, making it easier to smooth out. Proper ironing techniques can help maintain the quality and lifespan of garments.
