How often does the Rocket Appartamento need to be descaled?
Scale build up is caused by hard water. If you don't use hard water you won't have scale buildup. I recommend avoiding the need to descale by using soft water and by soft water and I mean water that is less than three grains of hardness or fifty parts-per-million. If you do this you won't need to descale so I do not recommend descaling Rocket espresso machines as I recommend avoiding the need to be scale by using soft water.
