Topic: cleanliness is next to god-shotliness (7 msgs / 142 lines)
1) From: Zara Haimo
Between an intense school schedule all spring and too many out of town trips this summer, I sort of forgot about cleaning my espresso machine regularly.  The last couple of days, I realized that I couldn't taste the difference between 2 very different beans.  Then I noticed that my espresso machine had a sort of bronzed look where I thought it should be stainless.  To make a long story short, I got out the Joe Glo and soaked and cleaned everything.  The espresso machine had a lot of gunk trapped around the shower head and even the basket holes were a bit clogged.  What an amazing difference a clean machine made for the next shot I pulled!  
If you haven't cleaned your equipment lately, this is a gentle reminder not to let things go as long as I did.

My strong suggestion is to have an extra PF that you keep a backflush blank
in at ALL times and keep said PF on the drip tray. Then water wiggle with
blank and water backflush after EVERY shot session, even if it's a single
shot. This helps keep group clean between weekly or so detergent
backflushings. Also rinse the PF thoroughly including spouts if you got 'em
and basket with just off boil water after every single shot. I use hotwater
on demand for this, if don't have one use your machines water tap or group.
(Of course you should flush the group after every single shot anyway to
clear the screen of any stray grinds, but that's before using group water
for rinsing PF.) Helps keep the PF clean between detergent soakings and
scrubbings. Make it a habit, it's been mine for many years and is second
nature.

I do have an extra PF with a blank and backflush frequently with water only. 
What I hadn't done was the detergent (Joe Glo) backflush I usually do once a 
week or any time I pull a lot of shots in a day.  I probably had more than a 
month's worth of gunk that had settled in around the shower screen and was 
dulling the taste of the shots I pulled.

"Backfulsh 'frequently' with water only". How frequently was/is frequently?
I was dead serious when I said after every shot session even if it's only a
one shot session. If I'm not going to immediately pull another shot it gets
the blank water wiggle followed by a couple quick water backflushes with a
wiggle between each backflush. Everytime, long time force of habit now. Oh,
always wiggle before first backflush to clear any loose grinds and not force
them back into the group and or 3-way.
If some of the basket holes where actually getting clogged I'd also review
how well you're hot water rinsing and wiping the basket after each shot and
especially end of shot session.
But a month would indeed be a long time between detergent cleanings!

Normally, I'd use Joe Glo to backflush and to soak the PF and baskets at 
least once a week, but somewhere around the time finals hit in mid-June, I 
stopped doing it.  I've been out of town more than 50% of the time since 
then, so there was probably about a month's worth of gunk built up since the 
last cleaning.  I hadn't realized how much that could dull the taste of my 
shots!
I backflush with water after almost every shot since I usually just pull one 
at a time.  I was stunned at how much brown gunk came out when I cleaned 
with Joe Glo today.  I actually ran detergent through twice to make sure I 
got it all.
I have 4 baskets, so they get thoroughly washed (I thought) after each use, 
not simply rinsed each time.  I was surprised at how much gunk must have 
been trapped in the holes, but they're sparkling clean now.
Fortunately, I have a naked PF, so there's no place for gunk to collect in a 
spout.
I haven't run minute rice through my Mazzer in a while either - that's 
tomorrow's project.

I follow Mike's procedure and I am sure it is one of the reasons my
machine (Expobar) is still going strong after 4 years of steady use.
I have only had to replace a presurestat, and it was an easy fix.
One needs to replace gaskets and maybe even the shower screen at least
annually.

I brush the dispersion screen clean, backflush after every shot and 
use Cafiza every month or 3 and on the occasional  times I've pulled 
the screen before using Cafiza it seems unnecessary. It's always been 
spotlessly clean.
