Special descaler for all types of coffee machine

Limescale deposits in the machine lead to longer brewing times and poorer heat transfer. This means that the optimum brewing temperature for the development of the coffee aromas  reached, which impairs the taste of the coffee. Limescale deposits can be a hygiene problem and are an ideal breeding ground for bacteria and mould. Limescale builds up in the machine over time and can clog fine pipes. Limescale also promotes corrosion of the materials in the coffee machine. Both can lead to defects. Limescale deposits lead to increased energy consumption of your coffee machine and thus pollute the environment. Internal tests show that 1 millimetre of limescale increases energy consumption by 8.1%. We recommend regular and early descaling, ideally every 3 months for optimum coffee quality as well as a long machine life.

Our durgol fast descaler is basically suitable for all household items. For open systems such as filter coffee machines, it can be used without any problems. For coffee machines with closed systems such as fully automatic coffee machines, capsule and pad machines as well as espresso machines, on the other hand, it requires a different formula with significantly less foam formation. Foam formation in closed coffee machine systems can lead to excessive pressure in fine lines and valves and thus to bursting or damage. The special descaler durgol swiss espresso was specially developed to descale coffee machines of all types and brands highly effectively and gently. The limescale is removed efficiently in a single pass.

A descaler removes limescale from the water-bearing components (mainly in the heating system) and ensures hygienic cleaning. Regular and thorough descaling prevents blockages and the accumulation of bacteria. A cleaner removes coffee oils, coffee fats and coffee powder residues in the brewing unit up to the coffee outlet. Regular cleaning is important to prevent bacteria from accumulating in the brewing unit. This is because oils, fats and coffee residues (polysaccharides), together with heat and moisture, are an ideal breeding ground. Both regular descaling and cleaning are essential components of coffee machine maintenance.

The cleaning or degreasing of coffee fats and oils is done with alkaline ingredients (caustic soda etc.). The removal of limescale, on the other hand, requires acidic ingredients. These two very different ingredients are not compatible in their chemical properties to be integrated in only one product and at the same time ensure the best possible cleaning or descaling performance for coffee machines. Therefore, we developed specific products for descaling and for cleaning respectively.

Thanks to its yield and above-average limescale dissolving capacity, durgol swiss espresso is very economical in dosage and thus leads to a significantly better environmental balance in the consumption of cleaning agents and packaging. durgol swiss espresso contains no environmentally harmful phosphorus or aromatic hydrocarbon components. The acid content contained in the product is precisely matched to the applications and is completely neutralised during the reaction with the lime. If acid residues (e.g. due to incorrect dosing) get into the waste water, they are still harmless, as there is usually an excess of so-called alkalis in waste water (due to detergent residues) and the acid residues help to neutralise or break down these alkalis in the waste water.

durgol products have a shelf life of 3 years from the date of manufacture.
