Limescale is a hard, chalky deposit, consisting mainly of calcium carbonate (CaCO 3). It often builds up inside kettles , boilers , and pipework, especially that for hot water. It is also often found as a similar deposit on the inner surfaces of old pipes and other surfaces where hard water has flowed.
The Program on Reproductive Health and the Environment at UCSF offers additional tips to help minimize exposure to toxic chemicals, like those sometimes found in microplastics.

Softened water cannot be considered as truly demineralized water, but does no longer contain cations responsible for the hardness of water and causing the formation of limescale, a hard chalky deposit essentially consisting of CaCO 3, building up inside kettles, hot water boilers, and pipework.
Health effects are an important consideration in many areas, such as hygiene, pollution studies, occupational safety and health, ([nutrition]) and health sciences in general. Some of the major environmental sources of health effects are air pollution, water pollution, soil contamination, noise pollution and over-illumination. [citation needed]
Some of that may have to do with the onset of seasonal affective disorder (SAD), which affects about 5% of the U.S. population and is triggered by shorter, darker, colder days. Car accidents increase.
It is frequently used for removing rust and limescale, replacing the more volatile and irritating hydrochloric acid, which is cheaper. It is often a component of household descalant, for example, Lime-A-Way Thick Gel contains up to 8% sulfamic acid and has pH 2.0–2.2, [12] or detergents used for removal of limescale.
