Nespresso instructs its customers only to use lactic descaling solution or the guarantee may be void. However lactic acid can be hard to get by and Nespressos own solution is heart-stoppingly expensive.

What could the reasons be not to use citric acid and is this a valid argument for the Nespresso machines?
