How to descale a coffee machine | HG provides you with 2 methods and a series of steps

If you descale your coffee machine regularly, your coffee will taste better. Scale in the coffee maker means the taste deteriorates, the coffee is colder when it comes out the machine and the machine produces more noise. On this page we provide you with tips on how to descale your machine and how to prevent scale.

Cause of scale in your coffee machine


Scale in the coffee maker is caused by calcium and magnesium salts in tap water. When you make a cup of coffee you heat your appliance. The heat means these salts stimulate the issue of scale. Scale particles end up in the coffee and produce scale in the machine. This is at the expense of the performance of the machine. A scale-free appliance produces better coffee and a coffee machine that lasts longer.

Descaling a coffee maker with vinegar.

According to a range of blogs and fora, vinegar is a popular descaling solution for descaling a coffee maker. Mix a few teaspoons of vinegar with water and leave this mixture to run through your machine. The disadvantage of descaling with vinegar is that your coffee has a nasty taste.

Furthermore, vinegar does not dissolve the scale, it breaks it up. It means that the loose scale particles can still block the pipes of your machine. So select a proper coffee machine descaler that was developed specifically for that purpose, such as HG quick descaler.
