Do you have questions about one of our products? Would you like to know more about our descaling agents? Then you can read many answers to the most important questions here. Please contact us if you cannot find the answer to your question below.
The lime deposits are dissolved by the acidic components in the descaler.
The intensity of this reaction can be seen from the strength of the air bubble formation. The effectiveness of a descaling agent largely depends on the acidic component. An ideal descaler guarantees fast and complete descaling with maximum protection of the materials if dosed sufficiently.
During the development of the product, special emphasis was placed on fast and safe descaling with high descaling performance. This was initially very difficult to achieve due to the strict requirements. But the set goal has been achieved. The result is a product that can compete in absolute terms with other descaling agents and also meets all required environmental aspects.
Tip: Pour the used descaling solution or the remaining contents of the bottle into the toilet bowl and let it work until the next use. This has the following advantages: any residual acid can remove limescale and urine deposits in the toilet just as effectively. The empty product bottles should be thrown away with the household waste, although all durgolf bottles are made from PET in the same way as standard drinks bottles. Manufacturers of all products sold in PET packaging, but not intended for drinking, are not allowed to become members of PET Recycling Switzerland. This means that dedurgol bottles - even after careful rinsing - are sorted before the recycling process.
Limescale deposits in the machine lead to a longer brewing time and poorer heat transfer, often less water output, which together results in poorer quality of your coffee.
Limescale deposits build up in the machine over time and can eventually clog it.
Lime also promotes corrosion of the materials in your coffee machine. Both can damage the machine. Limescale deposits lead to higher energy consumption in your coffee machine and are therefore harmful to the environment.
We For optimal quality of your coffee and a long lifespan of your machine.
Lime is important for us humans...Lime is in principle not bad.
It is even healthy for us humans: Calcium helps, among other things, to build bones. Therefore, calcareous water is good for the human body. But unfortunately, lime is harmful in the household...
Calcareous
Limescale deposits on equipment lead to poorer heat transfer and therefore to higher energy consumption. Limescale deposits promote the growth of micro-organisms such as bacteria. Limescale deposits can affect the operation of appliances such as kettles and coffee makers and shorten their lifespan.
Limescale deposits can negatively affect the operation of household appliances (e.g. kettles and coffee makers) and their lifespan. Limescale deposits in coffee machines can clog the pipes and thus significantly shorten the lifespan of the machine. The lifespan of kettles can also be shortened, for example due to overheating and damage to the electronics. durgol helps to break down limescale deposits efficiently and gently.
To descale the appliance safely, household products such as citric acid or vinegar should be avoided as a descaling agent, as they are less efficient and usually cannot remove limescale deposits completely. Products containing citric acid can form insoluble deposits, which sooner or later lead to problems with the descaled appliances. Products containing acetic acid also dissolve silicone/rubbers, such as gaskets, making them brittle and potentially causing a leak. And not unimportant, they both also leave an unpleasant taste.
What is lime?
When tap water is heated, limescale deposits are formed in appliances such as espresso machines, kettles and washing machines.
Example
Limescale deposits in an espresso machine will negatively affect the quality of the coffee and the lifespan of your machine.
Cause
•
Limescale deposits prolong the coffee brewing time.
• This means the machine supplies less water.
• The temperature continues to decrease as a result.
• This results in poorer coffee quality.
• The limescale layer in the machine becomes thicker over time and causes blockages.
• Limescale deposits lead to increased energy consumption. Solution To ensure optimal quality of your espresso and a long lifespan of your
machine, it is important to descale your machine regularly and in a timely manner.
Simple
Traditionally, people with filter coffee machines want to solve the problem by putting a little less water or a little more coffee in the filter (scoop with a lump of coffee).
But the cause is most certainly lime and the solution in this case is Durgol universal. Durgol
Durgol is odorless and does not leave an unpleasant taste in your kettle or coffee machine, so the coffee taste optimally remains in the machine.
How does lime get into tap water?
Hard
This hard water reaches households as tap water. When tap water is heated or evaporated, limescale deposits are formed.
You can obtain reliable information about the water hardness in your place of residence or region through Depending on your region, you have one of the following water suppliers: Brabantwater, Dunea, Evides, Oasen, PWN, Vitens, Waterbedrijf Groningen, Waternet, WMD Drenthe or WML Limburg. You can often deduce from the name which supplier you currently have.
Water hardness dH
German hardness (dH) indicates the hardness of water and indicates the concentration of metal ions, often magnesium and calcium carbonate, but also bicarbonates and sulfates, in the water.
Most drinking water contains calcium that precipitates as calcium carbonate when heated. This is called lime, limescale or scale. Water with a high water hardness causes a lot of limescale deposits and thus damages heating elements, but also makes the action of soaps more difficult.
The latter can be found in the dosages for the dishwasher or washing machine. Drinking Water
The quality requirements for drinking water are set out in the Drinking Water Decree.
Requirements apply to water supplies and pipe networks, among other things, with regard to hardness and the availability of a measuring program. No specific requirements are set for drinking water treatment for residential installations. Water that is too .
The national drinking water decree only stipulates that water supply companies may not soften or desalt drinking water further than 5.6 Dh for hardness . The upper limit is often set at 12.5 dH.
The average hardness for Dutch drinking water is around 8 German degrees. This is prescribed because water that is too soft damages the copper pipes. What is hard water?
The hardness of water is measured by the amount of calcium and magnesium. The more calcium and magnesium, the harder the water. The boundary between hard and soft water is difficult to represent. The concepts are relative and there is no official hardness scale in the Netherlands.
• 0-4 dH
• 4-8 dH
• 8-12 dH
• 12-18 dH
• 18-30 dH
very soft
soft
medium
hard
very hard
The hardness of water in the Netherlands varies per municipality, or even per place of residence.
Because tap water is reprocessed from as many as 200 different sources, there are differences in Dutch water hardness. Water on the Veluwe can be called soft, while Houten in Utrecht has very hard water. Check the hardness of your tap water. Limescale forms from 2.7 dH.
You therefore need more washing powder and other cleaning products, your central heating system uses an unnecessary amount of energy and your bathroom and kitchen need extra maintenance to remain streak-free. Your skin feels drier due to hard water.
For example, our municipality:
Bemmel (Gld)
Your province: Gelderland
Your water hardness: 7.1 dH
Your water is hard.
Kettlestone is limestone and its origins
Kettlestone is limestone (CaCO3) that is formed when heating or boiling water.
Especially in hard water, which contains many calcium and magnesium ions, a lot of scale is formed when heated. The scale hinders the proper functioning of the heating device and is also harmful to an existing heating element. Ketelsteen owes its name to the boilers of steam engines and heating equipment, in which it deposits as "stone" on the walls. Hard water contains a lot of lime in the form of the fairly soluble calcium hydrogen carbonate, Ca(HCO3)2, which means that calcium (Ca2+) and hydrogen carbonate (HCO3) ions are present in the water.
When heated, carbon dioxide escapes and solid calcium carbonate is formed (and also as a result of the magnesium ions present, magnesium carbonate):
Ca2+(aq) + 2 HCO3-(aq) overrightarrow{leftarrow} CaCO3(s) + H2O(l) + CO2(aq) )
The calcium carbonate (plus magnesium carbonate) is heat insulating and is therefore bad for heat transfer in, for example, a heating element.
The above reaction is actually a composite of two equilibrium reactions.
Hard tap water puts a strain on your home, skin and wallet, but also on the environment.
It causes unnecessary use of aggressive cleaning agents, soaps, energy, unnecessary burden on equipment, sanitary facilities, and unfortunately; even more... Hard water causes clogged water pipes.
Limescale deposits adhere to the inside of water pipes.
This adhesion causes a greatly reduced flow. Calculating the kitchen and bathroom
Here you can quickly see the consequences of hard water.
A white-yellow deposit on sanitary facilities and shower walls, dull taps and streaks. Even consistently drying out wet areas such as the shower cannot prevent this. Thermostatic taps become clogged or even break
. Taps cannot handle limescale.
The temperature control is even worse than visible parts. They get clogged or they break. Greater risk of corrosion and rust, especially with porous limescale deposits.
Corrosion and rust go hand in hand with limescale. This can cause leaks in the long term. Devices break down or show leaks. Coffee & Espresso machines, dishwashers and washing machines last less long with hard water. A combi steamer is very resistant to limescale.
• Limescale deposits in your espresso machine can negatively affect the quality of the espresso and the lifespan of your machine.
• This limescale deposit extends the coffee brewing time and causes poorer heat transfer, which in turn results in poorer espresso quality.
• The limescale layer in the machine becomes thicker over time and can cause blockages and constrictions.
In addition, limescale affects your espresso machine and also causes corrosion. This can lead to damage to the machine. • Limescale deposits lead to increased energy consumption of your espresso machine, which is harmful to the environment.
• To maintain the optimal quality of your espresso and to guarantee the lifespan of your machine, it is important to descale your machine in a timely manner.
The lime deposits are dissolved by the acid component in the descaler.
The intensity of the reaction can be read from the extent to which bubbles develop. The effectiveness of a descaler largely depends on the acid component. An ideal descaler ensures fast and sufficient descaling when used in the correct dosage and at the same time guarantees maximum protection of the material used in the machine.
When descaling with a citric acid-based descaler, sediment can form that can clog the fine pipes and valves in your espresso machine.
In addition, the citric acid can form an insoluble layer that, as it were, seals the lime layer. In addition, descaling with citric acid takes at least 10 times as long as with durgol® swiss espresso®. Vinegar or vinegar essence causes an unpleasant odor during descaling due to the acetic acid contained in it and the flavorings.
In addition, the plastic material in your espresso machine can eventually take on this taste, affecting the aroma of the espresso. Some plastics can be affected by acetic acid. As with citric acid, descaling with vinegar is much slower (>10 x) than with durgol® swiss espresso®.
Durgol Swiss Espresso has been specially developed for descaling espresso machines (= closed systems).
Durgol Swiss Espresso is very effective against limescale, but does not damage the machine. Compared to Durgol Universal, Durgol Swiss Espresso has little or no foaming or effervescence.

Descale your espresso machine regularly and early!
Depending on the machine type, you can determine the time for descaling as follows. • Machines with a warning light: set the machine to the hardness of the water according to the manufacturer's instructions.
This can be requested from the water company or determined with a special test strip. As soon as the warning light comes on, the machine needs to be descaled. • Machines without warning light: descale the machine as soon as it starts to function more slowly or irregularly or when the quality of the foam layer (“crema”) decreases.
We recommend descaling regularly and in a timely manner, ideally every 3 months. For descaling and rinsing, first follow the instructions for your coffee maker.
Complete descaling of your household machine is only guaranteed by using an entire dosing bottle of Durgol Swiss Espresso (125ml) per descaling operation.
