I'm giving my rather abused laPavoni Europiccola a bit of a service. I was wondering whether one needed to grease the piston at all. I am conflicted because it seems like I ought to, and have seen it mentioned online, but don't want any chance of any grease getting in the espresso. Does anyone have a similar machine?
I have also noticed quite a limescale build up, which seems resistant to my usualy soak in tartaric acid solution. I was assuming I am just descaling the boiler, so it should be easy to rinse out and shouldn't damage any seals, would it be worth using something a bit stronger, and has anyone any recommendations.
