Hey everyone,

I've done a lot of research and figured out what I think my cleaning regimen should be for my Gaggia Classic.  This post isn't so much about whether or not to backflush and how often to do so, nor is it about whether to use tartaric or citric acid based descalers on aluminum boiler machines.  I want to use powdered Urnex Cafiza for backflushing and Dezcal for descaling.  However, the single-dose packs (for "home use") of those two are dramatically more expensive than buying the loose powder (for "commercial use").  Does anyone know if the home-use single-dose packs and the commercial bulk bottles of the products (which go by the same name) contain the same forumla?  I want to make sure that the descaler, especially, has the same buffering agents/anti-corrosive products as the home-line.  I tried asking Urnex but haven't heard back.  Thanks!

I am sorry I can't speak toward the formulations. However, what I can say is the Cafiza loose powder works very well indeed. So much so that I use less than what is recommended for my Breville 900 with excellent results.

I expect the product is the same in different packages, but I have no proof.

I decided to look as similar has been asked before and I do not remember an answer.  

http://www.urnexbrand.com/products/Dezcal_Tablets.aspx

MSDS for each

Tablet    Citric <60%   Sulfamidic  <15%

Liquid                         Sulfamidic  <20%

Powder   Citric  <60%  Sulfamidic  <5%  Aluminum Sulfate <1%

All say for "for professional technicians and home users" and perhaps the difference is quantity.  I did not see another distinction between home vs commercial and the MSDS is by product name so there does not seem a commercial formula different.  I did not see a specific notation on the site but the Powder with the addition of Aluminum sulfate is probably to help the balance for aluminum boilers.

As long as I was there,

Cafiza Powder for backflush

Disodium carbonate, compound with hydrogen peroxide  <20%
Sodium dodecylbenzenesulfonate, pure                          <5%
Sodium carbonate                                                        <5%

Cafiza Tabs for cleaning of superautos, or for backflush

Sodium carbonate                                                         <35%
Disodium carbonate, compound with hydrogen peroxide   <22%
Sulphamidic Acid                                                           <20%

I guess the power of the solution could be lessened if you don't use it frequently. They appear to have expiration dates but I haven't studied the affects. So if you get the big container and it sits awhile the result could be less than stellar.
