I was able to procure a cheap Grindmaster Espressimo 1750 and the boiler, the heating coils, and boiler lid are caked on with hard water buildup.  Its bad, probably why they got rid of the machince, because it doesnt work, the gasket needs to be replace and once I get it clean I am pretty sure it will work again .  Anyways I have been soaking all the copper parts(coils and lid) in an citric acid bath and its been cleaning them up really nicely.  The boiler itself though is aluminum and I need to get it clean.  I can't use citric acid or the cafiza I have, so what can I do?  Vinegar?

There are some threads about descale of the Gaggias with aluminum SBDU boilers.  Many Use Citric acid. Acetic can be used also, but similar strength as I recall and with Vinegar the smell/taste to get rid of. There is Gaggia decalcifier used on aluminum and several other products.

Cafiza is more for backflush, cleaning oils.

I might have to go with Durgol Swiss Espresso Decalcifier

I can understand backflushing with citric acid, but there aren't any good recommendations in there for soaking.

Tartaric acid and sulfamic acid are used with aluminum for descale.  IIRC, they are slower than citric and more likely to take extra cycles if heavy scale.  Sometimes you see the one or the other combined with citric.  I have read thread where citric was recommended, and sometimes not.  YMMV

Citric is really not for backflush, as backflush is mostly for coffee oils and cleaning agents, not acids are used.  Acid are not great oil and residue removers and cleaners not good with scale. What is the "soaking" question?  Soaking what parts?

I need to soak the whole boiler (which is freaking huge in these like 7 liters) in something since the scale buildup is terrible.

That seems the ideal for citric, especially if disassembled.  Use citric and the rinse several time when done.  Some worry about dissimilar metals, but if just the boiler...  With Gaggia opened some use a Dremel tool, grinder and/or wire brush.  

Try citric and gaggia in search, one is listed in the above post.

Also try Dremel and Gaggia, here is a start.

You may need a rotary tool and then clean up with citric or your descaler of choice.

Search about Gaggia descale and you will find plenty of ideas.

Hi Anthony,

I have an Espressimo 1750 that needs to be repaired. I live in NYC and see you repair these machines. What is the best way to get in touch with you?
