These 2.5g tablets are the same as the Puly Caff powder but in tablet form. They are intended for use with beans-to-cup machines or for those that prefer a more convenient measured dose. Either put one into your beans-to-cup machine as per the manufacturer's instructions and run the pre-programmed cleaning cycle, or simply place a tablet in the blind filter when backflushing an espresso machine that has a commercial-type group head (one with a pressure release mechanism).
If your machine is not suitable for backflushing then these tablets can be dissolved in warm water and the resulting solution used to clean the group head, filter holder and filter baskets. We recommend you wear gloves for this.
