Scale is the biggest enemy of all household appliances that involve the use of tap water. JURA has developed a cleaning tablet to extend the service life of your coffee machine by removing dirt and yet still being easy clean on your machine. JURA coffee machines were certified as extremely hygienic by independent international testing organisation TÜV Rheinland in accordance with its own strict criteria. This proves that JURA maintenance products, precisely formulated to be effective with the electronically controlled programmes, guarantee TÜV-certified hygiene and cleanliness for every JURA coffee machine. When water is heated, limescale is deposited. Pipes narrowed by limescale not only slow down the heating process and therefore consume more energy, but may even cause the machine to break down completely. Limescale also has a negative effect on the coffee itself. Although a small amount of calcium carbonate is important to the flavour of coffee, too much gives the water an unpleasant aftertaste and prevents the coffee aromas from developing as they should, partly due to fluctuating water temperatures.
