What is limescale and why does it build up in coffee machines?
Limescale is a hard, chalky deposit that primarily consists of calcium carbonate. It forms when water that contains dissolved minerals, particularly calcium and magnesium, is heated and then cooled. As the water evaporates or is used up, these minerals precipitate out and accumulate on surfaces, creating limescale buildup. In coffee machines, this can lead to reduced efficiency, poor water flow, and ultimately affect the taste of your coffee.
Over time, neglecting limescale can cause significant damage to your coffee machine. The buildup can block pipes and affect heating elements, leading to malfunctions or even permanent damage. This makes it essential to regularly decalcify your machine to keep it functioning optimally.
