The Causes of Limescale and What to Do About It

Limescale is a form of mineral build-up that tends to occur on surfaces. It can be found on anything from the inside of pipes to your sink, and it’s just as common in water heaters as it is on faucets. Limescale has many causes, but the most common is an overabundance of calcium or magnesium dissolved in water. Fortunately, there are some things you can do to prevent limescale from forming–or at least slow its progress

Limescale causes

The most common cause of limescale buildup is excess calcium or magnesium dissolved in water which will react with any exposed metal surface and harden over time into a white crusty substance. This process happens more quickly when hot water is used because limescale can form when water cools, but limescale doesn’t really get a chance to. Limescale will also form in extremely hard water (water with high mineral content), and very softened water (with low mineral content) which creates limescale by the way of “scale softening”. A limescale buildup can also form when the water is acidic, but limescale formed in this way isn’t really problematic.

What is limescale

Limescale is a hard, whitish mineral scale that builds up on the inside of pipes, sinks and other metal surfaces in contact with hot water. It is less common on dishes and cooking utensils. Limescale items usually only need to be descaled every few years and it does not affect the taste or effectiveness of water.

How limescale is formed

Limescale is a hard, whitish mineral build-up that forms when there is too much lime or magnesium dissolved in the water. This causes an excess of calcium and magnesium which reacts with any exposed metal surface and hardens over time into a white crusty substance. This process happens more quickly when water is hot, limescale can form when water is cooled but limescale doesn’t really get a chance to. Limescale will also form in extremely hard water (water with high mineral content), and very softened water (with low mineral content) which creates limescale by the way of “scale softening”. A limescale buildup can also form when the water is acidic, limescale formed in this way isn’t really problematic.

How to prevent limescale

To prevent limescale build-up in your home, the following steps can be taken:

– Use softeners that prevent calcium from being dissolved in your water

– Boiling water and allowing it to cool before use, as well as adding a decalcifying agent such as salt or vinegar when boiling

– Place items which are likely to form limescale in the dishwasher or leave them overnight in a solution of water and vinegar

– Make sure that the hot water tank is fully insulated, as a poorly insulated one will increase limescale build-up

– Never pour cold water into a kettle that contains hot water as this will cause the formation of limescale inside it.

– Clean off limescale buildup at least once every few years.

– Using a filtered kettle that aerates water as it boils can help to prevent limescale build-up within the home

– Not letting lukewarm water stand in the kettle for too long

– Using softeners that prevent calcium from being dissolved in your water

– Installing an anti-limescale filter such as a kdf filter- Boiling water and allowing it to cool before use

What are the dangers of limescale?

Limescale may be harmful for your health if you happen to consume it. It may build up in places where you put toothpaste, making it difficult for you to scrape off with your finger and causing your tube to go bad faster than it should. It can also affect the taste of water, making it seem metallic or salty-tasting
