My chemistry has mostly been lost from my memory banks.  I could guess that it may help with some balance of ph, or help balance a chemical equation to keep aluminum in the boiler wall as opposed to ionizing and making the salts.

thanks. i think dezcal wins. here is from urnex's website. I think i'll just run it through 6 oz in brew and 6 oz in steam. then only let it sit like ten minutes before flushing out. Is this similar to what you'd do?

Can Dezcal™ be used on copper and aluminum?
Dezcal™ can be used on coffee machines with aluminum and copper heating units for short periods of time. Our formula contains a corrosion inhibitor. However, with extended exposure to acids, aluminum can pit and lose its lustre. When copper is in contact with acid, the oxidized portion is cleaned (similar to taking the green off of a roof). When copper is in the acid solution, it will redeposit back onto itself, so there is minimal concern for damage.
In general, we only recommend use of our products in the manner which is described on the packages. In the case of descaling with acids, we suggest avoiding extended exposure and just using the product and rinsing thoroughly after use.

Although it also says this

What is the difference between Cleancaf® and Dezcal™?
Cleancaf® is first and foremost a cleaner designed to keep your machine fresh and your coffee tasting great. It also contains a component that works as a scale inhibitor. When used regularly on a new machine (or one which has not already developed a significant scale problem), it will work to prevent the accumulation of scale buildup on the internal parts of the machine.

Dezcal™ is specifically designed to address the need to remove hard water deposits. Dezcal™ is engineered to remove even the toughest scale buildup from machinery, but is not intended to clean away coffee oil residue as well as Cleancaf®.

This leads me to believe that cleancaf is used for maintenance and dezcal is used when you know there is a problem. The ingredients in cleancaf on the box i have are sodium tripolyphosphate and sodium carbonate. I'm not exactly sure how these affect aluminum.

More practical instructions, backflush with Cleancaf and descale with Descaler.  My problem with the scale inhibition is that I still do not know how much scale there is, so descale.  Especially if you did not start with a new machine.  With backflush the solution should not enter the boiler.  Aluminum contact is mostly the dispersion disk and you can at least see that.

I do not think that you will have difficulty with almost any product used as directed.  As I noted, Tex who I believe runs the Gaggia user group at yahoo cleans with citric and has been a big proponent of that. He has a lot of info out there.

Update, perhaps better is Dezcal for descale and Cafiza for backflush.  I can't find enough to compare Cafiza and Cleancaf.

Not to intentionally revive this topic but...

What is everyones opinion of the Durgol Swiss? I see a lot of people saying its great with aluminum boilers but no where do they say whether it actually removes scale (actually works)? The seattle coffee gear review says they couldn't identify scale or anything in the rinse. So just curious if someone who uses this product has ever opened their boiler and checked whether its scale free or not?
