Calcified?
Sonett's limescale remover has proven indispensable in the household. It removes stubborn limescale from fittings, tiles, sinks and toilets. It is also suitable for decalcifying cooking pots, coffee machines and washing machines. The citric acid contained is better suited than other acids due to the discreet smell and the gentle effect on metals and plastics in the kitchen and sanitary area. In addition, it can be rapidly degraded by the microorganisms present in nature to carbon dioxide and water.
