What is limescale?

Limescale is a hard, chalky mineral deposit of calcium carbonate that builds up inside kettles when hot water evaporates and solidifies.

Why do we need to remove limescale?

Not only is it extremely unpleasant to find hard lumps of limescale floating in your tea, it's important to keep your kettle free of limescale as it can slow down the heating process.

Limescale builds up in layers around heating elements so more energy is required when heating water. The result is a reduction in efficiency and an increase in running costs.

It's particularly important to descale your kettle around once every three months in hard water areas.
