Clean Express coffee grease remover | For cleaning portafilters

Cleaning the brewing group from coffee fat using a blind sieve (also called backflushing) is important, as the coffee fat becomes rancid over time and the brewing group sticks together. You need a blind sieve, which exerts a high counter pressure on the entire brewing system due to the closed bottom and through the The excess pressure thus built up flushes the system backwards.
