Hi all,

It's been a while since I dabbled with my espresso machine.  I just primed it, and now I want to descale it.

I know that I should remove the shower screen while descaling, but what about the shower screen holder plate.  Also, does it help to soak the shower screen and holder plate in citric acid?

A different but related question - when cleaning with cafiza, I used to soak the shower screen in it.  If citric acid isn't the right way to go, do I soak the shower screen holder in cafiza, or is the blackflush I usually do good enough?


Thanks guys!
Rich

Cafiza only removes stuck coffee oils that otherwise would go rancid, while citric acid only removes scale. The first can be done by backflushing. However, after a while there's still some gruel accumulated behind the shower screen, so it's wise to remove it from time to time. Descaling is also required regularly, the interval depending on the water you use.

By the way, the boiler of the Gaggia Classic is made of aluminium. It's no good using citric acid on it, because it damages the boiler. It's better to use tartaric acid.

I hadn't thought of the material question, vs. the cleaner used, but - yes I'd remove that piece that the screen screws into it. It has a channel through it that can and will get clogged with scale. It's pretty easy, 2 socket head cap screws, 5mm I believe. The gasket should pop out pretty easily at this time as well, might be a good idea to check it's condition.

You may already be aware of this, but I thought I'd throw it out there (it's the Gaggia group on yahoo.  There's quite a bit of great info out there on these machines.)
