Limescale removers. Selection of domestic limescale removers. Limescale is a hard white deposit found inside kettles and around taps, sinks and toilet bowls that is formed when dissolved salts present in water come out of solution as the water evaporates. A major component is calcium carbonate which comes from limestone. Limestone removers contain mild acids that 'dissolve' the calcium carbonate.
