limescale
Kettle's chalky buildup
Limescale is the hard, chalky deposit that builds up inside kettles, pipes, and other surfaces exposed to hard water.
It forms when dissolved calcium and magnesium carbonates precipitate out as water evaporates or is heated.
The kettle's heating element was coated with limescale.
Removing limescale typically requires acidic cleaners like vinegar or citric acid.
