What Is a Kettle Descaler?

A kettle descaler is a chemical or natural substance specifically formulated to remove limescale buildup from electric kettles and other appliances that heat water. Limescale is primarily composed of calcium carbonate, which precipitates out of hard water when it is heated, leading to reduced efficiency and potential damage to the kettle over time.
