Origin and properties of the ingredients

By-products from the sugar industry, such as molasses, are the raw materials for the production of citric acid. During the decalcification process, the citric acid, in its general capacity as an acid, acts on the precipitated limestone and dissolves it again with the evolution of carbon dioxide.

Technical specifications

Density: (20 °C) approx. 1.073 g / cm³ pH value: (20 °C, 5 g / l H₂O) approx. 3-4

Store between 10 and 25°C if possible.

product feature

Due to its quality as a food ingredient, its restrained odor and its gentle effect on metals and plastics, citric acid is more suitable than other acids for versatile decalcification in the kitchen and sanitary area.

scope of application

Wherever heavy calcification occurs, the limescale remover can be used effectively.

Attention: Citric acid has a lime-dissolving effect. Please keep away from calcareous surfaces such as marble, concrete, engineered stone, limestone, etc.


The limescale remover can be used effectively wherever heavy calcification occurs, on fittings, tiles, toilets, saucepans, coffee machines, washing machines, etc.

Application undiluted

For fittings, tiles, toilets – where the limescale remover cannot be heated – allow it to act for a few minutes depending on the layer of limescale, then rinse off thoroughly with clear water.

Application diluted

In saucepans and for descaling machines - where the acid can be heated and is therefore more effective.

Dosing kettle

Heat approx. 100 ml per 0.5 liters of water to approx. 60 °C, leave on for 20 to 30 minutes and rinse thoroughly.

Dosing coffee machine

Pour 200 ml of limescale remover and 800 ml of water into the coffee machine's water reservoir. Descale according to the instructions for use of the machine. A subsequent passage with clear water is absolutely necessary - until the water is clear.

Dosage 4.5 kg washing machine

Add 1 liter of limescale remover to the 60 °C main wash cycle without laundry. Run the wash cycle and clean the lint filter.

Dishwasher dosage

Add 1 liter of limescale remover to the main wash cycle of the longest rinse cycle (after the pre-rinse!) - with or without dishes. Let the program run to the end.


Citric acid is a component of the plant, animal and human organism and is therefore quickly and completely broken down into carbon dioxide and water by the microorganisms present in nature.
