The DeLonghi EcoDecalk contains 200 ml, which is sufficient for two descaling processes. EcoDecalk is an ecological descaler with a 100% environmentally friendly formula that effectively combats limescale deposits in coffee machines. The solution contains only natural and high-quality raw materials of plant origin (lactic acid), which are biodegradable and non-harmful to the environment. Regular use of EcoDecalk allows for a longer lifespan and better energy efficiency of the coffee machine, as the accumulation of limescale can increase energy consumption by up to 30 percent.
