Several small espresso machines such as the Rancilio Silvia have a three way valve that releases head pressure when the brew button is turned off. This causes some of the brew liquid to run back through the head and out into the drip tray. This means that gunge builds up in the head behind the shower screen and in the plumbing, including the three way valve. Eventually this will cause the valve to fail. Cafiza cleans the head, the plumbing and the valve. I have found it to be very effective when used weekly. It only takes a few minutes, but it will definitely prolong the life of your machine. I wish they told you about Cafiza in the machine manual, it really is magic!

This does exactly as it says! Cleans our coffee machine, removes coffee stains we couldn't live without this and the price and delivery are very reasonable

Seems to do its job and clean out any coffee residue. You need a backflush disc to use it.

Cleans well enough. The amount of coffee oils it removed is amazing.
