What is limescale?
Limescale is a white deposit that’s also known as calcium carbonate – it’s the reason your kettle needs regular cleaning.
Limescale is found in places where hot water has evaporated and some of the remaining deposit has solidified. You might have also seen it on old pipes, water tanks, and central heating systems. It’s especially common in hard water areas because the water is high in dissolved magnesium and calcium.
How often should you clean your kettle, Your kettle needs cleaning and descaling regularly. We recommend that you:
Clean the outside of the kettle once a fortnight, or as needed, Treat limescale once a month – if you live in a hard water area, you might want to do this more frequently
How to descale your kettle
