Correct dosing saves costs and protects the environment. Use the fast descaler undiluted or diluted 1:1 with water, depending on the degree of calcification.

Examples: kettles, saucepans, vases, toothbrush glasses, baby bottles, etc.

Depending on the quantity of residual limescale, fill the container with diluted or undiluted durgol universal so that it covers the limescale completely. Leave to act for up to 30 minutes. If the solution stops generating foam, but visible limescale is still left, the active substance is used up and you should add more durgol universal. Afterwards, thoroughly rinse the container with cold water.

Examples: tap filters (jet regulators), shower heads, nozzles, etc.

If possible, detach the parts and place them in diluted or undiluted durgol universal for up to 30 minutes. Rinse with cold water and dry any metal parts.

Examples: sinks, chrome steel troughs, fittings, aquariums, etc.

Soak a cloth in durgol universal and remove all limescale residue. Rinse with cold water and wipe dry. For cleaning surfaces, we recommend durgol bathroom descaler and durgol kitchen cleaner, which are produced using a special formula that ensures the right consistency for this purpose.

Pour 1-2 cups  (1 cup = 150 ml) of durgol universal into the water tank and dilute with tap water. Let the solution run through the machine twice. Afterwards, run two cycles with just tap water. We recommend our special product durgol swiss espresso for all automatic coffee makers and capsule/pod/espresso machines.

  • When descaling household appliances, always take read the manufacturer’s instructions in the appliance’s operating manual.
  • With metal, durgol universal must be used cold.
  • Do not combine with other cleaning products.
  • After the descaling process, rinse the appliance with cold tap water and dry any metal parts.
  • Use only on undamaged, acid-resistant materials.

Frequently asked questions 

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.

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

The more limescale that has accumulated, the more descaling solution is needed. If the limescale does not dissolve completely during use, this means that not enough descaling solution has been added and the acid agent has been used up. In this case, simply add a little more descaling solution and let it work again until the limescale is completely dissolved. As our descalers have a very high limescale dissolving power, we recommend a sparing dosage, which should only be increased if necessary.

Thanks to its yield and above-average limescale dissolving capacity, durgol universal is very economical in dosage and thus leads to a significantly better environmental balance in the consumption of cleaning agents and packaging. durgol universal 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 universal has a particularly fast effect and a high limescale dissolving capacity. durgol universal bio also dissolves limescale quickly and reliably, with minimal environmental impact. durgol universal bio is >99.5% biodegradable in 18 days and is therefore the more environmentally friendly option. The ecological added value is regularly tested and confirmed by the renowned SGS INSTITUT FRESENIUS. durgol universal bio has a slightly reduced limescale dissolving speed compared to durgol universal but is still 5 times faster than vinegar & citric acid.
