All good things come in threes — this applies to the service life of an appliance too. The 3AntiCalc function, as the name implies, is a threefold function comprising SelfClean, Calc'nClean and a built-in AntiCalc System. It effectively prevents the build-up of limescale in your appliance and reliably increases the service life of your Bosch iron. The special soleplate with its 3-phase design guarantees an ideal distribution of steam and maximum gliding. The triple-zone ironing technology includes moistening, drying and smoothing processes. This ironing process, together with the sophisticated arrangement of the steam channels, makes this household chore significantly more convenient and less stressful.
