Coming to buy a given automatic machine DeLonghi, I wanted to take a prudent descaling brand. Bottle for 4 cleanings. Too bad that within the same brand, the notice is also unclear about the amount of water in which to dilute a dose: . record descaler returns to record machine . the instructions for the machine returns to record descaler For the first use, when in doubt, I choose the amount of water given default (1 liter)
Next time I water down the dose in the completely full tank!
