Benefits at a glance

Biodegradable 

Biodegradability of >99.5% after 18 days, tested and confirmed by SGS INSTITUT FRESENIUS. Free from perfumes, dyes and preservatives. 

Powerful descaling effect 

Quick and thorough removal of limescale. 500 ml of durgol universal bio dissolves approx. 30 g of limescale, 5x faster than citric acid or vinegar. 

Safe and gentle on materials 

Effective corrosion protection ensures maximum protection of materials. Food-safe. Leaves no chemical residue after use. 

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

Depending on the quantity of residual limescale, fill the container with diluted or undiluted durgol universal bio 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 bio. Rinse thoroughly.

To dissolve external limescale residue, place the pot in a larger container and proceed as described above. Then rinse the container thoroughly with water.

Place in a container filled with durgol universal bio for up to 30 minutes. Afterwards, rinse with water.

Please read the manufacturer’s instructions.

Always use durgol universal bio cold. Do not mix with other cleaning or washing products. Use only on undamaged, acid-resistant materials. If in doubt, test on a concealed area first.

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.

durgol universal bio removes limescale from all household items reliably and gently, with minimal environmental impact. durgol universal bio has a biodegradability of >99.5% after 18 days and meets the criteria of "ready biodegradability" according to the OECD 301E guideline (tested by SGS INSTITUT FRESENIUS). In addition, durgol universal bio contains no unnecessary ingredients such as fragrances, colourants and preservatives. The classification "ready biodegradable" is the highest biodegradation level that can be achieved. This is regularly tested and confirmed by the renowned SGS INSTITUT FRESENIUS. The regular checks ensure that the sealed product durgol universal bio permanently meets the strictly defined test criteria. The product is also very economical. The strong efficacy enables particularly economical and environmentally friendly dosing and thus leads to a significantly better environmental balance in the consumption of cleaning agents and packaging.

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.
