Interesting information about limescale

Hard water is a widespread phenomenon. This water is perfectly safe to drink, but it can damage household equipment and appliances. Everything you need to know about limescale and descalers can be found here. 

Why is descaling so important?

Lime is important for us humans...

  • Lime in general is not bad. In fact, it is even healthy for us humans, because it contains calcium that promotes bone formation, for instance. This is why hard water is good for the human body.

Unfortunately, it has the opposite effect on our household goods...

  • Hard water leaves behind unsightly limescale when the water evaporates or is heated up.
  • Limescale deposits in appliances interfere with heat transfer, resulting in increased energy consumption.
  • Limescale promotes the growth of microorganisms, such as bacteria.
  • Limescale can impede the functioning of appliances, such as kettles and coffee machines, and shorten their service life.

What is limescale and how does it form?

Lime (in chemical terms, calcium carbonate) was formed 600 million years ago from deposits composed of marine organisms. Limestone mountains later formed from these sedimentary deposits. Hard water occurs when rainwater seeps through calciferous rock strata and is enriched with calcium carbonate. This hard water enters our households as tap water. When hard water is heated or allowed to evaporate, limescale forms.

durgol or household products? What is more effective?

durgol has clear advantages over household remedies like citric acid or vinegar, which are not recommended for a gentle and effective descaling of appliances. Compared with professional descalers like durgol, household remedies are less effective and usually do not get rid of limescale completely.

  • Products containing citric acid can form an insoluble sediment that ultimately leads to problems with the descaled appliance.
  • Products containing vinegar dissolve softening agents in plastics, particularly seals, making them brittle. They also leave an unpleasant taste.

Why not use water filters to prevent limescale?

  • Because essential calcium is then no longer ingested through drinking water.
  • Ion exchangers and activated carbon filters also carry a risk of germ contamination.
  • The absence of minerals can also affect the taste of the water negatively.
  • Our bodies and the environment are additionally subjected to sodium chloride (salt) released by some ion exchangers. This is particularly bad for babies and those with high blood pressure. After all, we consume too much sodium chloride (salt) in our food anyway.

All this applies to water softening systems if they are set incorrectly.
