A garment steamer is a device used to remove wrinkles from clothing and fabrics. It works by heating water to produce steam, which is then directed onto the fabric. This steam relaxes the fibers, making it easier to smooth out creases without the need for an iron. Garment steamers are often lightweight and portable, making them convenient for home use or travel. Unlike traditional irons, which require a flat surface and can sometimes scorch fabrics, garment steamers can be used on hanging clothes. They are effective on a variety of materials, including delicate fabrics like silk and polyester, making them a versatile tool for maintaining a polished appearance.
