A self-cleaning steam iron automatically heats up when water is poured into it, thereby allowing the device to clean itself with powerful steam blasts. This feature can be beneficial when your device’s filter is clogged or if you live in an area that has hard or chlorinated tap water. It should be noted however that this feature uses quite a bit of power and only works for about 10 minutes in most cases. Also, during the initial few times of using this function, it may take some time before steam actually starts coming out of your device. However, one benefit of using this option is that creases are easier to remove after being pressed because residual moisture has already been removed.
