De'LonghiEcoDecalk Descaler, Eco-Friendly Universal Descaling Solution for Coffee & Espresso Machines, 16.90 oz (5 uses)

Packaging and delivery were good. Although everything is written in Italian, so just make sure you watch the Delonghi You Tube video on proper usage. This bottle is enough to descale my la specialista espresso machine 5 times giving me the value I was looking for versus the smaller sizes. Does a nice job cleaning everything up including the steam wand.

This is my 7th De'Longhi machine and I love them. The decalcifier works great and is so much easier than before I got my Magnifica.

Descaler works great in our machine!

This the scaler works very well. The color is clear when you add it to the water during the descaling process I think the quality of this is great works perfect every time decently priced.

Actually works, but there were no instructions on how to use it on the box or on the bottle. In fact, there was barely any English the product packaging at all. The top language was Hungarian, and it was only the hazard instructions. I had to consult DeLonghi’s website to find out how to use it.

Works just as described

Worked great

I had used Keurig Descaling Solution since I bought my latest machine. Faithfully. Not necessarily from this seller or even site, but the same product, and it's expensive. A long-time Keurig (indeed, Cuisinart before that) owner, I am familiar with the signs that a descaling is necessary, and my current machine will even tell me when I forget.Tiring of the expense and noting the ingredient list for a knock-off product that listed it, I perused Amazon for citric acid, the non-toxic base ingredient Keurig uses. I found it in many forms: powder, liquid, even tablets. The price varied extensively, but when I saw this product from such a respected name and at a great price per use and in my beloved Subscribe and Save program, I knew I had to give it a shot.It works like a charm. I'd say, better than the OEM Keurig solution and for half the cost per use. There are four applications in this bottle, while you use the whole bottle of the Keurig brand. While it's simpler to pour the entire bottle in the tank, it's much more spendy.The De'Longhi does have one issue: the instructions can be difficult to locate in English or whichever language is your primary. You'll need to lift the sticky tape that many manufacturers of bottle products are now using and page through all the paper to find your language, but the directions are likely there for you, and they are definitely included in English - after all the safety warnings. Keep looking! There are handy markings on the side of the bottle, as well, so just pour out the amount to the next mark into the tank and you're ready to continue.I have found that the machine actually responds better and needs descaling less often with this product than when I used the OEM Keurig solution, and I run a LOT of KCups. I use the brewer often, for coffee, tea, chai, whatever. I even use it to start hot water for cooking at times. My husband uses it, too, though just for coffee. So, it will need more descaling than average, I expect, and this product is the one I'll be using until I find something better. Right now, I see no reason to go looking for one, since it's a great product at a nice price. With Subscribe and Save, I get an even better price, too! I do recommend you give it a try in your machine. It's wonderful.
