Durgol Universal, Multi-Purpose Descaler and Decalcifier for Household Items, 16.9 Fluid Ounces (Pack of 2)

This is a GREAT product, and this is the second bottle I'm ordering because it does a beautiful job of REMOVING the chemicals from the bottom of our stainless steel electric kettle, in just one hour! :) We use the kettle daily to boil water for "drip coffee" and tea, every morning, so the "build up" of chemicals from our Brita Water Pitcher (which has tap water), is a constant challenge. Having this product available is great, because I know that whenever I'm tired of seeing the buildup at the bottom of the kettle, I can remove it easily, and with no worry of breathing any unhealthy fumes!

I bought this to remove built up mineral and calcium deposits on my bathroom sink faucets. I removed the aerators and soaked them in a bit of this Durgol descaler. It honestly only took about 15 minutes per faucet to completely clean them and made them look brand new! Highly recommend this for your sinks.

This cleaned my teapot so good I can't believe I'm just now finding this. Wish I would've knew about this before...I've thrown away a few teapots because of the lime in the bottom that wouldn't come out but now I have this, I'm saving money and my cute teapots

I had previously rated this 1 star as instructions are not in English so didn’t know how much to use. I looked on the internet and it stated 150-300 ml. Didn’t mean much to me so I emailed the company in the Nederlands and explained that I needed instructions in English. I advised that I had a 1 quart saucepan and not a coffee maker. They advised 150 ml as they did not know how much calcium build up I had and suggested 1/3 c product and 1/3 c water. Calcium was not too bad as I use SOS pads to clean it. I waited 3 days and tried the instructions and to my surprise the calcium lifted off in about 10 seconds and saucepan looked new.

I was skeptical about needing this product. For years we've used lemon juice or vinegar to clean the mineral deposits from the bottom heating plate of our electric tea kettle. But we moved to a place with lots more minerals in the water, and the old solutions weren't cutting it. Vinegar had to sit in the kettle for a long time to get all the white stuff out, and lemon juice didn't work at all. Searched for a solution and found this product. Comes from Europe, where tea kettles are a staple, so I figured it was worth a try. I was surprised by how fast it worked. Previously, we had to leave vinegar in the kettle for 10-20 minutes, and even then it didn't remove everything. And it smelled. This product worked in about 20-30 seconds and it removed every last trace of white scale. Seemed expensive, but just a small amount cleans the kettle, so per-use cost isn't bad. I figure this 25 oz bottle will last us at least a year, maybe two. I really like finding a product that does what it says it will do. This one does. Great solution if you make heavy use of an electric kettle with hard water. Exceeded my expectations.

I have not used it yet my sister told me to get it to remove hard water spots she swears by it. I should’ve gotten it in a spray bottle though

Durgol Universal did an excellent job of cleaning our coffee maker. We can literally taste the difference.

Great product

Excelente producto contra la cal acumulada

Dieser Entkalker ist der beste von denen die ich bis heute kennen gelernt habe. Es war reiner Zufall, weil ich mir eine neue Kaffeemaschine der Fa. Petra kaufte und diese Firma diesen Entkalker empfahl. Ich bin sehr zufrieden damit, weil er auch die letzten Kalkreste mitnimmt. Er ist nur zu empfehlen.

Used many times cleans coffee machine perfectly

I bought to descaler my bodum bistro water kettle. Only a little to cover the surface and half an hour later, my kettle is like new!

This says it’s for coffee makers, I believe, but it works better than anything else I’ve tried on “warm” humidifiers. They can quickly build up very thick mineral deposits. Can be diluted - 1/3 Durgol, 2/3 water or as weak as 1 to 5. The solution works just as well as undiluted, just takes a longer soak, so this product is actually quite inexpensive. It even works when it’s not in direct contact with scale. My new humidifier’s “heating element” sticks up about a centimetre over the water when the unit’s base is as full as it can be (and of course the solution when I use that). There’s always a “cap” of scale left after cleaning, although I can thin it down by scraping. (It seems to be impossible to turn the unit upside down and soak the element that way!) The last time I cleaned my latest humidifier and put one tank full through, (with that cap of scale still sticking to the element), I thought I’d check to see if I might be able to scrape more scale off when it was hot and there was perhaps a bit of descaler in the solution from cleaning. (It works sometimes.) When I pushed at one edge, the cap just popped off! I’ve used all sorts of descalers with all sorts of warm humidifiers where the heating element can’t be covered completely by the anti-scale solution but the top of it still gets a thick deposit just from the steam. This is the first time the scale came off completely and easily. This product is worth every penny, as a thick layer of scale on top of the heating element makes the humidifier much less effective, until it overheats and quits working..
