Hey everyone,
I have an Elektra mini-verticale. It makes wonderful espresso (I use Danesi espresso). I would like it to continue to do so for many years, and that's why I've been thinking about removing any hard water deposits inside it safely. I believe it has a marine brass boiler.

I use Volvic water in it, which possesses 130 mg/l total minerals, 71 mg/l HCO3 and 11,5 mg/l Ca. Therefore, I assume eventually I'll need to.

I bought the machine in Italy, and there were no instructions regarding maintenance in any language on the single piece of paper I got with it.

Anyone have any ideas. (By the way, I live in Germany, so I may not be able to get certain brands available in the US.)

Thanks

I use food grade citric acid.  You can usually find it at a homebrewers supply shop or a soapmaking shop.  I run about a quart of water with one tablespoon of citric acid into the boiler.  I let it soak for maybe an hour and then flush with two or three quarts of fresh water.  The best thing about citric acid is is doesn't leave a funny taste behind like vinegar.

Thanks a lot for your help. Yes, vinegar is the least desirable alternative...

I have used Brew Rite Cleaner. You can find it most places with coffee pots ect. It is sodium carbonate, also known as soda ash.
