Topic: Descaling Krups Gusto (10 msgs / 156 lines)
1) From: Ben Treichel
I am presuming that Urnex is not the proper stuff to use on a Gusto, and 
also presuming that Urnex is not either citric or tartaric acid. Am I 
presuming correctly?
Also I am making my first buy of expresso coffee and I'm going to get 
2#'s of Sweet Maria's Espresso Monkey Blend,  2#'s of Sweet Maria's 
Classic Italian Espresso Blend, and 2#'s of  Sweet Maria's Decaf 
Espresso Blend. I know everybody seems to like monkey blend, but I 
really haven't heard anything about the other two. ??

I'm not sure about the Urnex. I was wondering about it myself, as I also 
own a Gusto.
As for the other two blends, I highly recommend them. I am working 
through a freshly roasted batch of Classic Italian right now. It has a 
nice caramelly taste to it. The decaf is also excellent, IMHO hardly 
distinguishable from caffeinated.

I've seen that with all of the SM decafs.

Urnex is not a descaler, rather a detergent that 
dissolves coffee oils. In commercial machines it 
is used for backflushing. In a home machine 
without a three way valve like the Gusto, running 
a tank full of water with a few tablespoons of 
urnex through your machine will clean out any 
accumulated coffee oils in the group or boiler. If 
you're getting hints of that bitter, rancid "old 
coffee" taste; it's the best cure.
Descaling for home machines is best done with a 
mix of two tablespoons citric acid per liter or 
quart of water. 5 lbs of food grade citric acid (a 
lifetime supply) at a brewer or soap supply store 
costs about $10, the same as a few packets of 
"cleancaf" or all the other descaling mixes sold 
by home espresso manufacturers at breathtaking 
markups.

Another product which was recommended to me by the owner of an espresso 
repair shop was Cream of Tartar. As with the Citric Acid, you would 
probably do well to look in places where they sell in bulk. The supermarket 
price for a few oz's is ridiculous....

Well, now, that's not what the description at SweetMaria's says (see http://www.sweetmarias.com/prod.coffeecleaner.shtml). It starts out 
with "Urnex Cleancaf is a coffee maker cleaner and descaler ..."  My 
experience is that it descales my drip machine nicely -- the second pot 
is always full of fluffy precipitate that I assume is "dissolved" scale. 
 Near the end of the description, Tom (or whoever writes his copy) says 
"recommended ... as a through-the-tank cleaner for many espresso 
machines"  *
*
So, I'd say that it's a fine product for descaling a Gusto.  Dissolve it 
in warm water, fill the tank with the solution, and run it through. 
 Then run a couple of tanks of clean water through.  That's what I do, 
anyway.

Urnex is the stuff that comes in $20 bottles that 
lasts for a year, Cleancaf (by Urnex) is 3 packets 
at $10 dollars, each packet being a table spoon of 
urnex, a table spoon of citric acid, and some blue 
dye.
Cleancaf will clean and descale a Gusto, but one 
flush of urnex, followed by one of citric acid 
will do it better for about 1/10 the cost.

Where can I get citric acid?  I've asked at a couple of stores, and nobody
knew nothing.

I got my lifetime supply at http://www.snowdriftfarm.com/dry.htmlThat was about half a year ago; googling on citric 
acid may turn up something cheaper.

Most wine and beer making supply stores should have it also.
