The naturally occuring minerals found in water can build-up inside your coffee machine, causing premature breakdown. The De'Longhi EcoDescaler significantly reduces the likelihood of premature breakdown from scale build-up which in turn improves the machine's performance, keeping a consistent brew temperature and flavor. De'Longhi's ecological, fast-acting descaling agent has been scientifically formulated and tested to effectively and safely remove limescale and mineral deposits. As worldwide leaders, we intimately understand coffee and espresso machines. Our unique solution is suitable for other brands and models of coffee makers.
