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

I use this cleaning solution to clean my tankless water heater. There are many methods to do it and products, but I've found this one to be the best value for money and very easy to use. It's safe and it's a powerful cleaner that produces a clean quality end result. Don't hesitate to purchase.

This product worked very well to clean my coffee maker that was not working at all. I hadn’t cleaned my machine in a long time and it was so clogged that it put off excessive steam and brewed almost no coffee. After running a double strength mixture through the machine followed by a regular strength mixture it is now working well. Highly recommend.

This stuff works great for cleaning my tankless water heater. reasonably priced as well.

I had descaled my coffee maker many, many times with the vinegar/water solution, and my $200 coffee maker still wouldn't work. One time using this, and it's like I've raised Lazarus from the dead. Coffee maker works like new. Tiny complaint - it took a about ~10 days to arrive, so I'd recommend getting it before it's an emergency. EDIT - Days later, I'm still baffled at how well it fixed my coffee maker.

I just got a k150 Keurig for free from my wife's work because it was broken....she brought it home because I'm handy with everything....for about an hour of time to disassemble and reassemble then $2.00 of solder and the 2 capacitors replaced on the circuit board it was fixed....I got this stuff to clean it and the directions say to pour it directly in to the reservoir.... Don't do that. Make sure the reservoir is totally empty and mix the powder into about a quart of hot water.... Once it's dissolved fully pour it in.... I did this but it wasn't fully mixed and dissolved. There was a little bit at the bottom and even that small amount cost flow issues in the Keurig so I had to use a turkey baster to clean that out of the reservoir and dissolve it in more hot water.... The water came out initially with a tint of yellow and little white flakes in the water..... I just kept running water through it on via brew cycles....four full reservoirs later the water was super clear and clean.... It also seemed like the water got hotter the more clean it got... Maybe it was in my head IDK.... but the stuff worked great

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

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 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
