Limescale in water – formation, effects and solutions
We often hear about problems like "limescale buildup in the shower " or " limescale-encrusted coffee machines . " " How can I remove limescale? " Toilets, showers, and kitchens are particularly affected. But have you ever wondered what limescale actually is?
Lime, chemically known as calcium carbonate (CaCO3), is a natural substance that occurs in various forms in nature, such as marble and limestone. But what exactly is lime, and how does it form?
What is lime made of?
Limescale consists of three main components: calcium (Ca), carbon (C), and oxygen (O). Calcium is an essential mineral for the human body. It contributes to healthy bones and teeth and supports the function of nerves and muscles. When water evaporates, for example during boiling, calcium carbonate remains as a solid, white deposit, which we know as limescale. These limescale deposits often occur where water is heated or evaporates.
How is limescale formed and how does it get into drinking water?
To understand this, we need to look at the water cycle. During the cycle, water (H₂O) absorbs calcium as it flows through layers of limestone. The calcium dissolves in the water, much like sugar dissolves in water. This means that the solid calcium breaks down into tiny, invisible particles that disperse in the water. This is how the calcium gets into the water.
Besides calcium, magnesium can also be present in the natural environment. During the water cycle, water therefore absorbs not only calcium but also magnesium. Water hardness is determined by the total concentration of calcium and magnesium. The more calcium and magnesium the water contains, the "harder" it becomes. A high proportion of calcium and magnesium in the water results in what is known as "hard water.".
When calcium dissolves in water, it breaks down into microscopic particles invisible to the naked eye. However, as soon as the hard water flows from the tap, the limescale often becomes visible. Limescale deposits frequently occur in appliances such as kettles, showers, faucets, and toilets.
Hard water is perfectly safe and can be consumed without hesitation. In fact, the calcium in water can even contribute to your health. It consists of important minerals such as calcium and magnesium, both of which play crucial roles in health. Calcium supports bone and tooth development, while magnesium is essential for muscle health. The World Health Organization (WHO) confirms that these minerals can have positive effects on health.
A common misconception is that hard water is linked to arteriosclerosis, commonly known as " hardening " In reality, arteriosclerosis is primarily caused by certain dietary fats, not by the minerals in water. There is no scientific evidence to support a link between consuming hard water and the development of arteriosclerosis.
In conclusion, hard water is perfectly safe and even offers health benefits. Calcium and magnesium have proven positive effects on the human body. The healthy effects of calcium and magnesium on the human body are contrasted by the limescale buildup on dishes, pipes and technical equipment.
Stubborn limescale that has accumulated over time can be difficult to remove. To effectively and thoroughly remove existing
limescale deposits , you should first and foremost use suitable cleaning agents. The question often arises: what helps against limescale in the shower or how to remove limescale from the faucet ? Vinegar and lemon juice are particularly suitable, but should be diluted with water for safety. After you removed the stubborn limescale stains and restored the surfaces and fittings to their shine, you should have an effective limescale protection device , often also " limescale protection system " installed. This will keep your home protected in the long term and in an environmentally friendly way, and you can avoid harsh cleaning agents and excessive cleaning in the future.

No matter where you live, your tap water contains limescale. In some places, the tap water is " hard " in others " soft " The limescale concentration in tap water varies greatly depending on the region, city, or even within a municipality. Is there a limescale problem where you live? Enter your postal code here to find out if there is a limescale problem in your area.
