Decalcify egg boiler – this is the best way to proceed

Hard water and limescale deposits are a major problem in many areas of Germany. Almost all kitchen and household appliances must therefore be decalcified regularly. How best to do this with the egg stove, and what to look out for, you can read here.

Limescale deposits in kitchen appliances

Limescale deposits caused by hard water from the tap become a problem wherever water is heated above 60 °C. This is because limescale starts to build up massively above this temperature. At this temperature, lime begins to precipitate out of the water on a massive scale. It then accumulates on many surfaces.

The already deposited lime layers create more and more new crystallization points, on which all the more lime is deposited afterwards. This is why regular decalcification is so important to avoid exactly this effect.

Heavy limescale deposits also have an impact on the performance of the egg boiler. The heating power of the egg boiler decreases, but at the same time the energy consumption increases quite significantly.

The life of the device decreases and the egg stove switches off prematurely more often. In addition, due to the changed heating power, the set values are no longer correct, as the electronics are tuned to a functioning heating element. Therefore, limescale removal at regular intervals is practically indispensable.

Removing limescale from the egg boiler

The problem with the egg boiler is usually limited to the water bowl. However, it is particularly problematic here that the limescale deposits also burn in over time – and are then particularly difficult to remove.

The frequency of descaling depends on the amount of deposits that can be seen in the heating pan. Of course, the best thing would be to wipe away all the limescale residues that you see after emptying the bowl. This avoids extreme calcification in advance.

Cleaning agents

The best cleaning agents against lime are home remedies:

  • Vinegar
  • vinegar essence
  • Citric acid


You can simply add vinegar to the bowl and let it soak in. Then rinse and rinse thoroughly. In the case of burnt-in encrustations, you can also heat the vinegar to just before the boiling point and leave it to act in the hot state until

Vinegar essence

Vinegar essence should always be used diluted with water. The optimum ratio is 3:1 (3 parts water, one part vinegar essence). Vinegar essence often works better than vinegar because it contains more pure acetic acid and fewer additives.

Citric acid

You can mix citric acid powder with water according to package directions and use it like vinegar. However, make sure the citric acid does not come into contact with plastic parts.

When removing limescale, always pay attention to the sensitive coating on the underside of the heating bowl and therefore absolutely avoid strong scrubbing, aggressive limescale removal products or scratching cleaning devices.
