Dry irons are now the old-fashioned, classic type of iron. Its simplicity lies in only having to adjust the temperature of the iron depending upon the type of fabric. The benefit of the dry iron is that as long as it is never left unattended and monitored carefully while in use, it will not likely ever cause harm to your garments. Nowadays, the dry iron can be harder to find and is sometime more expensive. However, for some fabrics, such as silk, dry irons are the only option.
