I will be out of the office starting  11/26/2002 and will not return
until 12/02/2002.
I will respond to your message when I return.

I was given some Brew Rite cleaner and was wondering if it is safe to
run through my Classic and use for soaking the portafilter etc.  The
only ingredient listed on the bottle is sodium carbonate.  I tried
google and searching the list archive with no real luck.  I did see that
Tom recommends Urnex's Cleancaf and I believe sodium carbonate is one of
the ingredients.
Any help would be greatly appreciated.

I believe that the classic has a 3 way solenoid, so with a blank
portafilter disc, you can backflush it with the brew rite.
It should be fine for soaking the pf as well. 
I wouldn't dump it into your water reservoir. Descalers usually contain
citric acid to break down the mineral deposits that collect inside the
Just sodium carbonate will help get rid of old coffee oils, but you'll
have already addressed the oil collecting area by backflushing. If you
prefer to go cheap, you can pick up some citric acid in power from from
your local home brew store. (It's used for wine making)

No The Gaggia has an aluminum boiler. The use of citric acid is
contra-indicated in aluminum. Citric Acid should be used with glass or
brass. Citric acid will pit aluminum.

Citric acid is great also for cleaning stainless steel it keeps the
necessary patina in stainless where chlorine will destroy stainless and any
left on surface keeps working on the stainless etching it self into the

Citric Acid, also known as sour salt, is also good for burnt on food on pots
and pans as long as they are not Aluminum. Just soak the pot with burnt on
food over night in a sink of hot water with some Sour salt added. For taking
water stains off Stainless steel I use Jet Dri (The solution used to put in
your dishwasher to avoid spotting on glasses). Just remember to wash it off
immediately. Don't let it sit.

Good to know.  I was pretty sure that it wouldn't be a problem for the
externals, but was concerned about the internals.  I have only had this
machine for a few months and received it from Alchemist John, so I
know it was well maintained, but I figure I should go ahead and start
the cleaning schedule.
As mentioned by Barry in a later reply, citric acid does not play well
with an Al boiler.  Tom mentions two Urnex products on the site for
cleaning the innards.
I assume this means it is not effective at removing mineral deposits.  I
have used the stuff in a coffee machine that was getting slow to brew
and it brought it back up to snuff.  Is this likely not the same issue
(mineral deposits, that is)?
Thanks to you and everyone else who replied,

 Okay, so what do I think are the drawbacks of the Gaggia machines?
 Well, they have aluminum boiler tanks, not brass. This isn't too
 significant except that you should run a cleaner like Urnex's Dezcal
 Descaler or Urnex's Cleancaf through the tank, not Cafiza espresso
 machine cleaner. (Use Cafiza to clean the filter baskets and coffee
I will be ordering one of these products in the future but saw no need
to do it immediately if what I had was safe and effective.  No use in
spending money if I don't need to do so.
Take care,
