## Overview

De'Longhi EcoDecalk is a fast-acting, plant-based descaling solution designed to safely remove limescale and mineral deposits from coffee and espresso machines.

## Description

The naturally occuring minerals found in water can build-up inside your coffee machine, causing premature breakdown. The De'Longhi EcoDescaler significantly reduces the likelihood of premature breakdown from scale build-up which in turn improves the machine's performance, keeping a consistent brew temperature and flavor. De'Longhi's ecological, fast-acting descaling agent has been scientifically formulated and tested to effectively and safely remove limescale and mineral deposits. As worldwide leaders, we intimately understand coffee and espresso machines. Our unique solution is suitable for other brands and models of coffee makers.

Review: Must-Have for Coffee Lovers – Keeps Your Machine Clean & Coffee Tasting Great! - I’ve been using the De’Longhi EcoDecalk Descaler for over a year now, and I can confidently say it’s one of the most essential maintenance products for any espresso or coffee machine owner. Why I keep coming back to this product: • ✅ Highly effective – It removes scale buildup without leaving any residue or weird smell behind. I’ve used it on my De’Longhi Magnifica and also on a smaller Nespresso machine — worked flawlessly on both. • ✅ Eco-friendly – It’s plant-based and biodegradable, which is important to me since I’m using it regularly. • ✅ Easy to use – Clear instructions on the label, and one bottle gives you 5 full uses, making it good value for the price. • ✅ Better coffee after each cycle – The difference in flavor and crema after descaling is real. My espresso shots taste cleaner and more balanced. • ✅ Machine runs quieter and smoother – Every time I descale, I notice my machine works almost like new. Pro tip: Run a full rinse cycle after descaling and wipe down the drip tray and spouts. You’ll be surprised how much residue can build up even if you don’t see it. It’s easy to overlook descaling, but using EcoDecalk regularly has extended the life of my machine and improved my daily coffee experience. It’s now part of my monthly routine.
Review: Works well for my Delonghi - This bottle lasts me a while, through 3-4 decalcifying sessions. I find the price reasonable here and the item came wrapped in plastic for safety. However, this time the box and plastic did have a small puncture in it, but it didn't affect the bottle of solution inside, so it's fine.

## Questions & Answers

**Q: Amazon will not ship this to california.  other descalers are made from sulfamic and citric acids, which delonghi says will harm the machine.  ideas?**
A: Both lactic acid and citric acid are biological descaling (decalcifying) agents that are very suitable for descaling a coffee machine or other equipment. They are not aggressive descalers which only take off the lime scale and do not have any harmful effects on the machines. Both can therefore be used without any worry and the machine will work better, let the coffee taste better and extend the lifespan of the machine. Previously nearly all manufacturers advised a descaling agent based on citric acid. The reason for this is simple: it dissolves the lime better and therefore less active ingredients are required for a bottle of descaler. In addition, the raw materials for citric acid are cheaper to buy. So we think it mainly was the choice of our suppliers who could deliver this product cheaper than lactic acid. Nowadays, manufacturers are moving from citric acid to lactic acid. The reason being the sheer fact that they first recommended citric acid and now lactic acid for the same machines now indicates that it does not matter very much in essence.

**Q: Will this work on an EC155?**
A: In no uncertain terms, yes, though with caution in doing so. The correct dilution is one dose, (5 doses in bottle) per liter of water. The big worry is whether it removes TOO MUCH scale at once which could cause the internal valves or hoses to clog. If it is already clogged it probably won't work as it has to get through the water circuit to work. If it still does have flow, depending on usage history, amount of minerals in your water and descaling history, (if any) it could blast too much scale loose at once. Depending on the combinations of the variables it would probably be conservative on the dose and do it several times. And when doing so do it slowly and allow a couple of minutes for the solution to steep inside the channels by starting flow, pausing for a couple of minutes, starting flow again , over a course of 12 to 15 minutes. The solution as the machine is designed is meant to flow through the tap valve and not the coffee head. Then rinse with a full container of clean water after descaling

**Q: My bottle of ecodecalk came without instructions and i can't find any on the delonghi website.  does anyone know where to find them?**
A: Instructions are on the bottle itself, just peel off the plastic sticker on the side. Each 500 ml Bottle can be used to descale up to 5 times. The numbers on the side of the bottle measures exactly 100ml each. If you can’t open the bottle cap, use a small knife or scissors to cut and remove the white safety ring underneath the green cap. Then press the cap down and twist counter clockwise.

**Q: will this work on percolators?**
A: Most likely, However white vinegar works well in percolators since the liquid is re-circulated. This stuff is a one shot through and may be too strong

### ⭐⭐⭐⭐⭐ Great product at a nice price
*by R***E on April 5, 2017*

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.
