If you use a 50/50 combination of tap water and distilled water to fill your steam generator iron, you shouldn’t experience too much of limescale. However, over time, it’s only natural that your product will begin to show signs of this. Any electrical appliance that uses water is prone to a bit of limescale. Continue to use this water solution and regularly clean both inside your iron’s water tank and its soleplate to ensure its ongoing performance and health.
