When your coffee and espresso machine’s heating elements are compromised by mineral scale build-up, water does not heat to the proper coffee brewing temperature, causing coffee to taste bitter. Full Circle Descaling Powder removes mineral buildup such as lime scale from the heating elements of your machine. Without regular descaling, your coffee maker can become clogged, water becomes cloudy and overall performance and taste are diminished. Full Circle Descaler does not leave behind the lingering smell and taste of vinegar and contains only non-toxic ingredients. Descale once a month for coffee and espresso equipment that operates at its best and enjoys better-tasting coffee! Includes 2 single-use packets.
