HG Nespresso lactic acid-based descaler is specially developed for removing limescale from all different types of Nespresso machines. This lactic acid-based descaler is milder than the regular citric acid descalers and therefore works even safer but still has a better descaling effect, is odourless and also completely biodegradable. With regular use of this descaler, your coffee will continue to taste great, the machine will keep its speed and you will also enjoy your Nespresso machine for years longer!
