Numerous tests carried out through our years of research and development show that traditional household remedies such as vinegar and citric acid do not thoroughly remove limescale deposits despite very long exposure times. In addition, descaling with household remedies has other disadvantages. Descaling with vinegar can lead to corrosion of metal surfaces, i.e. to undesirable discolouration. Vinegar also attacks plastic seals, especially on household appliances. This can lead to defects. Furthermore, vinegar leaves an unpleasant smell and taste after descaling. Citric acid reacts with lime in a very negative way. If left to react for a longer period of time, insoluble deposits are formed, so-called citrates, which seal the limescale. Over time, these stubborn deposits clog the pipes of household appliances such as coffee machines or washing machines.
