Lime build-up or limescale deposits are deposits which are formed as a result of water usage. If the temperature of tap water changes, for example when cooking or when water is warmed in a heating system, then the lime-dissolving properties of the water also change. The higher the temperature, the less lime (calcium carbonate) can be held in solution. Any rise in temperature above 60°C eventually leads to extremely unpleasant lime deposits on e.g. fittings and tiles, and to limescale furring (calcium and magnesium carbonate) in pots, machines and pipes. Limescale deposits have a heat-isolating effect and thereby increase power consumption. Therefore water softeners should always be added to detergent if water is very hard (contains a high level of lime). In sanitary facilities, limescale deposits may be removed with acidic sanitary cleaners. To remove limescale in food preparation equipment, e.g. in kettles, the use of citric acid (cold to lukewarm) is recommended, since citric acid is generally considered safe.
