Irons are household appliances used to remove wrinkles from clothes. They work by applying heat and steam to fabric, making it easier to smooth out creases. Most irons have a flat, heated plate that glides over the material, and many models come with adjustable temperature settings for different types of fabric, such as cotton or silk. In addition to traditional irons, there are also steam irons and ironing boards designed to make the process more efficient. A steam iron releases bursts of steam, which helps to relax the fibers in the fabric, while an ironing board provides a stable surface for pressing clothes.
