Strong active, friendly and easy-to-use Descaler

When descaling of our coffee machines I had been placed on products based on lactic acid or amidosulfonic acid. Acetic acid, as they can attack seals and can taste set in the machine as well as citric acid because of possible attack of aluminum-containing surfaces I do not use if possible.

The Cromargan precious - Descaler uses amidosulphonic as the main active ingredient and comes ready to use in 4x100 vial. These are placed in the water tank, filled with water and start the descaling program. The descaling worked PROBLEM-and without residue (I descale because excessive water hardness and high coffee consumption about every 2-3 months) and therefore absolutely satisfactory.
After descaling and rinsing no aftertaste was noted, the coffee experience is unclouded.

All in all, the Cromargan a good and universal descaler for coffee machines. Sustainable would of course delivery in a bottle 400ml instead of 4x100, the devaluation that is not enough, however. Full 5 stars and buy recommendation.
