Simply amazing. If you have a decent espresso machine with a 3-way solenoid you need this.
I discovered this by chance. Having de-scaled using the Gaggia descaling solution and still getting poor flow through the group head and pressurised filter I learned that regular back flushing and cleaning of the filters is necessary.
It is important to note that back flushing is only for machines with a 3-way solenoid [e.g. the Gaggia Classic and some Baby Gaggias]. Do not attempt to back flush machines that do not have a 3-way valve.
Why backflush? Because the 3-way valve allows left over coffee to drain "backwards" from the "coffee puck", through the valve and out into the drip tray. This relieves pressure and makes for a drier coffee puck with less dripping. But that fresh espresso dries onto the inside of the screen area and the valve itself and soon becomes old stale espresso. By cleaning on a regular basis you will ensure that your lovely fresh espresso is not tainted by the last shot's, or worse, past years, flavours!
Having learned more through watching a few online videos I also discovered that pressurised filters are prone to clogging up due to the fact that the oils settle between the part of the filter with many holes and the single hole beneath.
Cafiza is something I wish I'd discovered sooner as it may have helped prevent my filter becoming clogged and it might have lasted longer.
However, after a back flush, using a blind filter purchased separately, and replacing the old filter basket with a new one, everything was back to normal and the Gaggia Classic is performing magnificently once again.
This stuff is magic in the way it cleans. Only a small amount mixed with warm water in a metal or glass [NOT PLASTIC] jug is needed to clean your portafilter holder, screen filter, filter basket and other peripherals. It works like magic on those tea tainted spoons too and even restored a tainted soy sauce bottle to a sparkling squeaky clean state.
