Regular descaling is essential to prepare the best espresso. The best way to do this is to use the Nivona NIRK 703 Premium liquid descaler, which was specially developed for the descaling program of the Nivona fully automatic machines in the CafeRomatica series. The descaler reliably and gently removes any limescale deposits and thus ensures that your coffee drinks not only taste better but also that your machine lasts longer. The 500 ml liquid descaler is sufficient for five descalings.
