Hello,
I've owned a Gaggia Carezza for the last 3 years. The machine works
wonderfully but lately I'm seeing some ugly and very persistent stains in
the brass portafilter after drawing shots. They're dark, rust colored stains
and they always appear in the same sections of the portafilter. I always
clean the pf as soon as the shot is drawn, never letting the old coffee sit
in the basket for any length of time. The stains get lighter after much
scrubbing with lemon juice, vinegar and Ajax scouring powder but you can
always see a faint outline and sure enough the next time I use the machine
they return in all their former splendor! It's like they're etched in the
brass! Please, help!

IF ist's localized to the same spot, it's possibly some iron impurity
in the brass

er....well I'm no metallurgist but that sounds a bit implausible; looks to
me like the coffee stain has somehow penetrated the surface in some places
near the bottom near the area where the radial edges of the filter basket
are closest to the portafilter. I'm just looking for a soaking solution of
some kind to get it off and tips so that it doesn't happen again.

I have got a solid brass lamp that has these impurities and is covered with
little rust spots I can't get rid of. So may be not so implausible?
