UrnexDezcal Activated Scale Remover - 7 oz - For Use on Commercial Boilers and Heating Elements of Coffee and Espresso Equipment

This is the stuff that really works!Majorly improved flavor after cleanout.

I have used this in both commercial & residential applications. First purchased it years ago to clean the urns & brewers at our shop. Snuck some home & went at it again. This will remove ANYthing that decides to take haven in your previous brew devices. Back to sparkling new again.

Arrived fast and packed well. First time using Dezcal I've always used a weak vinegar and citric acid solution I made up. Thought I would try a commercial product this time. I mixed it at about 1.5 tablespoons per quart of water. Pack should be good for four cleanings or so.This seemed to work great following directions. Following directions, I cleaned and descaled two espresso machines. First I mixed the solution then pumped into the machine enough solution that I could tell it filled the boiler. Then I let it sit for half an hour. You could see the lime deposits flushed out as I pumped out the Dezcal after the half an hour. You must flush out the Dezcal several times with clear water because it tastes terrible.My machines are both over 8 years old but I do maintain them by using only filtered water and descaling every 6 months or so. This keeps them running fine and coffee tasting good.

I'm giving it four stars because I myself did not use the product my husband did, BUT he did show me the amount of scaling and debris that came after using this. There was a difference for sure in the taste of the coffee and the performance of the machine. He had never used a product in the ten years he had it. I know "YUK"

We used this to clean our tankless water heater. This product cleaned really well, as there was sediment residue after cleaning and the tankless heater is only one year old. I highly recommend this product.

Works great but be careful to keep away from stainless steel, it's can make spot on your coffees machine steel.

I used half the bag for one descale of a Keureg. Couldn't get the descale light to go off, just "brewing" with the solution in the tank. Then read the manual, and there is a model-specific button combination to get it into descale mode. Now, that works. A tank of this, then a tank of clear water, and all is well. Oh, watch the dust when you handle this stuff. It is irritating if you breathe it.

I previously used vinegar to flush my tankless water heater. I will never use vinegar again after finding this descaler. I always thought vinegar did the trick. It was not till I used the Dezcal that I learned the vinegar did nothing in removing my limescale. I added 1 packet of Dezcal to each gallon of water used. FYI, this stuff is mostly Citric Acid, so you will find it to be safe and non-toxic
