These brew group cleaning tablets are specially formulated for all Capresso and Jura brand superautomatic coffee/espresso centers. Use these tablets for general cleaning of the internal components and for descaling. Scaling is caused by calcium deposits in your water that will eventually harm your espresso machine, or render it useless if left untreated. Scaling will also affect the taste of your coffee if left unchecked. We recommend that you decalcify your espresso machine every 2-3 months, depending on usage. Each package contains 6 tablets.
