NATURAL, ODORLESS CLEANING ACTION - K&J's proprietary blend of natural, food-grade ingredients has created a descaling solution that is 2x more effective than the leading brand and at least 5x more effective than vinegar! Proudly made in the USA. REMOVES MINERAL BUILDUP - Removes white buildup and grime from minerals deposited from water on your heating coils and reservoir tank walls, bringing your coffee brewer from old to new. INCREASES LIFE OF MACHINE - This special, natural formulation will not damage your internal parts and will, in fact, extend their lifetime by ensuring that they are working at peak efficiency. Proper maintenance and using the right cleaner is very important for the longevity of your brewer. IMPROVES BEVERAGE FLAVOR - When your heating coils are coated with layers of insulating deposits, these deposits must be heated before the water is heated. This produces a slightly metallic flavor that we call "deposit tea". K&J's descaling solution safely removes these deposits, eliminating this metallic flavor with no weird aftertaste. This K&J descaling solution for coffee brewers is specially formulated to take on your machine’s internal limescale buildup, while not being too harsh on its parts. This process not only protects your coffee maker but also greatly improves the taste of your coffee. Includes clear instructions, so you don’t need to figure it out yourself. Each bottle contains 2 uses, and is conveniently marked for each use. The custom formula will work across all brands of coffee and espresso machines, such as Keurig, Breville, Cuisinart, Phillips, Nespresso, Dellonghi, and more
