It is important to note that a steam iron will not soften a very stiff fabric like wool, denim, lace, or fur; if you want to soften such fabrics, you should use a dryer. Steam irons work best on freshly pressed fabrics, especially if you want to remove wrinkles from freshly laundered clothes. For heavy stains, use a detergent iron. In case your iron comes with attachments such as pin, you can use them to press heavy fabrics like quilts and blankets, which will prevent them from getting frizzy.
Apart from the numerous advantages of steam iron, it has several disadvantages which are also apparent. One of the disadvantages of using it is that its temperature varies according to its speed. Some clothes get damaged when they are pressed too hard, while some get damaged even before they are pressed. Hence, you need to be aware of the exact type of fabric you want to press and then go for the appropriate type of steam iron.
