🧼 Care & Usage
To maximize your backflush insert's effectiveness, insert the blind filter basket into your portafilter and add your preferred backflush cleaning solution. Activate your machine's brewing button and cycle water through the group head for 5-10 seconds until the water runs clear, then repeat several times for thorough cleaning. After each use, simply rinse the insert under warm water, dry thoroughly with a soft cloth, and store in a convenient location. Its compact square design requires minimal cabinet space. For optimal results, backflush your espresso machine 2-3 times weekly or after each heavy use.
