durgol® swiss espresso® is a special decalcifier for quality espresso machines of all brands, including fully automatic machines, half automatic machines, manual machines and "coffee pad” machines. Filter machines and electric water heaters can also be decalcified with durgol® swiss espresso®.

durgol® swiss espresso® is highly effective, easy and safe to use and is guaranteed to decalcify quickly and easily without the need to wait for the decalcification process to work. Regular use of the special formula will ensure the optimal quality of your espresso and extend the life span of your machine.

durgol® swiss espresso® leaves no residue and after decalcification and rinsing, your machine is completely safe for use.

durgol® swiss espresso® is available at selected specialized retailers in a package which contains two 125ml (4.2oz.) portions. One portion is designed to decalcify one machine once.

Why should you not decalcify your espresso machine with citric acid or vinegar?

During decalcification with decalcifiers on citric acid basis, residue can form and clog the fine lines and valves of your espresso machine. Lime deposits can become sealed under an unremovable layer of residue formed by the citric acid. Finally, decalcifying with citric acid works 10 times more slowly than with durgol® swiss espresso®.

Decalcification with vinegar or vinegar essence produces an unpleasant smell because of the acetic acid in vinegar. The plastic in your espresso machine can absorb an objectionable taste which will then leach into your espresso and compromise its quality.

Why is DURGOL...

Why is durgol® swiss espresso® the right decalcifier for your espresso machine?

durgol® swiss espresso® works 5-10 times faster than other branded decalcifiers. There is no need to interrupt the decalcification process to wait for durgol® swiss espresso® to work.
One portion (125ml) of durgol® swiss espresso® can dissolve up to 10g (0.35oz.) of lime. This is sufficient to decalcify one espresso machine once.
Because of its special corrosion protection formula, durgol® swiss espresso® will not damage your espresso machine when used correctly. No residue that could clog your machine will develop during decalcification.

durgol® swiss espresso® is easy and safe to use
Because of the high decalcifying speed of durgol® swiss espresso®, decalcification is fast and easy.
durgol® swiss espresso® comes ready to use. In contrast with powder or tablet decalcifiers, it is not necessary to dissolve durgol® swiss espresso® in water. Liquid durgol® swiss espresso® does not contain any additives, such as those found in tablets, which can clog your machine.
One portion (125ml) of durgol® swiss espresso® provides a complete decalcification for your machine. Other decalcifiers are often under-dosed and therefore do not completely decalcify your machine.

durgol® swiss espresso® is safe for you

Because of its strong lime-dissolving ability, durgol® swiss espresso® can be dosed economically and in an environmentally-friendly way. The single-use portions prevent overdosing.
