Backflushing with espresso machine cleaner

minor differences. The first difference is backflushing with espresso machine cleaner only needs

to be done approximately once a month or every 35-50 espressos. I don't recommend

backflushing with cleaner more often than once every three weeks since overuse will remove oils

that lubricate the brew lever and valves. You can water backflush as often as you prefer.

To begin, place 1/4 of a teaspoon of espresso machine cleaner into the blank portafilter insert,

then lock the portafilter into the group. Now follow the same procedure as above until the cleaner

is dissolved and the water runs clear (about 5-10 flushes). Remove the portafilter from the group

and rinse thoroughly. Then take a damp cloth and wipe the underside of the group. After you have

finished this procedure, I recommend you pull a shot of espresso and dispose of it to cure the

group. You're finished and ready for another month of espresso.

Note:

I only recommend using either Puro Café or Urnex Full Circle Espresso Machine Wash

because they are specially formulated for this purpose. The use of other cleaners may affect the

performance of your machine and could even damage it.
