Removed the boiler from my Gaggia Classic and it was a humbling experience to learn just how much scale can build up even on RO water.
Ultimately wasn’t able to get the boiler looking squeaky even after 2 hours of sitting in descale solution. Is that probably fine? I just rinsed and brushed it until I didn’t see any more visible scale flakes coming off. Flow is back to normal as far as I can tell.
Thanks! I took a look at the brass boiler and I’m thinking I might spring for that. I love the Gaggia so much after 7 years I still dont have any plan to replace it. This could be a good way to breathe some new life!
The Gaggia is a nice machine, especially if you mod it.
