How do I descale and clean the Electric Steriliser & Bottle Warmer?

After every use, unplug the appliance and wipe it with a damp cloth to avoid limescale build-up. At regular intervals, descale the base using household vinegar or a commercially available decalcifying agent according to the manufacturer's instructions. Never place the appliance in a dishwasher or immerse it in water, and do not use strong or abrasive cleaning agents. (Page 7)
