On my last trip to Portland just plain Mike told us about a neat way to =
clean the steam wand. We spoke about so many things I am not sure if I =
remember the easy procedure. Mike if you could repeat it so the whole =
list may benefit I for one would appreciate it. Thanks Barry

I have a Silvia and a Cremina and I find that a pipe cleaner works great...

What I do to clean the steam wand, at least weekly, is:
Use a frothing pitcher that can be wedged into the drip tray area with the
steam wand inserted.  I fill the pitcher with water and a couple spoons of
Puro Caf and heat it to 140 F or so.  Then, without taking the wand out of
the water, I wedge it into the drip tray and leave it for five or ten
minutes.  I reheat the water and let set for a few minutes several times -
again without ever taking the wand out of the water.  What is happening is
the steam in the water condeses causing a vacuum inside the wand which pulls
the strong detergent into the wand - all the way to the valve.  You'd be
surprised (and a little disgusted) at how much gunk it'll remove from the
wand.

As I remember you dissolve Cafiza in a steaming pitcher. Wedge the =
pitcher under the steam wand and steam it. Then shut off the steam. A =
partial vacuum is created in the wand and the Cafiza mixture is drawn up =
into the wand. Leave it sit for a few minutes and then flush . Is that =
right?

That's it . I had about 15 espressos that day and I think it effected my =
memory as well as my bladder.

I find the little needle on the end of the CoffeeTool brush works  
just fine to dislodge anything--and then a brief dip in clear water  
followed by blasting the steam does the rest of the job.

Just tried it. It works. Sandy just cleaning the tip and running hot =
water through it is not enough. You need to suck the cleanser up into =
the steam wand to dissolve the gunk. Then purge. Try it and be amazed at =
how much gunk accumulates.

As with anytime using a cleaning detergent, don't forget to repeat procedure
with clear water to rinse!

I just found out that the manufacturers (presently very few of them) who
offer the non-stick steam wands do not recommend using the procedure that I
outlined above.  The contention is that the strong detergents harm the
non-stick coating inside the wands.

I have a Wega Mininova and I thoroughly wipe it after each use with a
wet rag, then blow steam out again to clear the holes while wiping.
That's all I've had to do for the past three years to keep it clean as a
whistle (are whistles really clean?).

Depends on whether or not it is a steam whistle ...

When the wand vacuums in the solution, it can get into the boiler, and taint
the water, cant it? Each time you open the valve I think you risk sucking
the detergent into the boiler. Knowing this, isn't purocaf and cafiza toxic?

There is a valve that prevents it from going into the boiler. If the =
valve is defective your steam wand will be leaking.

I blow down as well, but fail to see how it can stop at the valve if you are
throttling it to flush steam into the solution. Anyway, stick to flushing
after each froth and im sure things will be good. Maybe ill explore and take
apart my valve assembly and look..

My thinking is, it is difficult for the gunk (no matter what it is) to go
the wrong way past the valve...against 16 to 20 psi of steam pressure.  When
I repair steam valves I see the gunk in the steam wand and valve assembly
all the way to and including the steam wand side of the valve.  The more
disciplined the barista is in wiping down the tip and blowing down the wand
quickly after frothing equals less gunk.....but always some.  I'm religeous
about blowing down and wiping the wand ASAP after frothing (before swirling
the milk etc. ), and I still see deposits from the wand when using this
procedure, when I do it every two weeks or so. YMMV

My thinking is; no matter how throttled the valve is......steam (or
condensate) is still flowing from the high pressure (boiler) side of the
valve to the low pressure (steam wand) side.
I don't think this is a really big deal, if you are disciplined about blow
down and wipe down as soon as possible after closing the steam valve.  Many
people aren't.
