Urnex K-Cup Descaler (3 Uses Per Bottle) - 14 Ounce - CleanCup Descaling Solution Use with Keurig K Cup and Drip Coffee Machine

Works great.

Cleans well. Have used this for several years

Seems to do the job as expected. No complaints except as another reviewer stated, I wish there were markings on the bottle to show how much to use.

This product does exactly what it's supposed to do: Clean your Keurig machine.You get three uses from one bottle (yes, it's frustrating they don't have a measurement on the bottle, marking the thirds). Put it in the regular Keurig water reservoir and start the Keurig going. Cup after cup after cup. Once low enough it won't run more water, take the reservoir off and rinse it. Then fill it up and run water through again, cup after cup after cup. You'll fill the reservoir up three times with fresh water, per the instructions, to rinse out all of this product.It's simple enough, but time consuming.Afterwards, your Keurig should be good as new.Personally, I like the Urnex K-Cup Cleaning Cups, too. They clean the needles, specifically, and you can see all sorts of soapy residue come through.One note: Keurig, themselves, states, in their instructions, to run a cycle without a K-Cup, just water, after each and every use. This helps keep the machine clean. Doing so will allow you to go longer without using products like this.

Really happy with this purchase. My lightly-used Keurig started acting up for the 2nd time since I've owned it and the vinegar trick (as well as other helpful tips & tricks I looked up online) just weren't working as well this time around. As a last resort I figured I'd buy the Keurig descaler/cleaner but decided after reading the reviews for this product I would save a little money and give this a try instead. Worked wonderfully! Since I had already tried several times to use other methods to clean it out, I used nearly half a bottle vs the 1/3 the bottle directions suggests and I ran it through several more times as well. It did work! Unlike other reviewers I did notice a very slight smell to the solution and thought I still smelled it a bit after running just water through the machine, so I did run just water through double the suggested amount. I also changed out the water filter even though it wasnt due for a new one yet, just to be safe. Definitely less of a smell/taste/hassle than vinegar though. I would highly suggest this product to those who have gotten the dreaded "descale" message on their Keurigs, or to anyone who owns a different type of coffee machine.

My Keurig B70 flashed up a little message indicating that I needed to descale. I really could not tell if there was a scale based flow issue as I often grind my own beans for use in eco-cups and commonly have too fine of grind which also reduces the flow. But, I love my Keurig so if it asks for something I will provide it. Off to Amazon to find some sort of descaling liquid... I followed all the directions for the CleanCup process and "maybe" the coffee tastes better and flows more freely? I haven't seen the message again anyway so it apparently did its job...Note that is only citric acid so you could also just do a search here on Amazon and buy enough crystallized citric acid to make many gallons for less than half the price of this product. Also, when the directions tell you to flush two times, make sure that you are sending the entire contents of the water reservoir through twice or get ready for a very harsh cup of chemicals.Ultimately, you are probably better off just using filtered water (brita, pur, etc.) whenever possible and cleaning with the generic citric acid when the little message pops up.

Product arrived as schedule and I use it every 3 months to keep Keurig clean.

I bought this product because I felt that after owning my Keurig for more than a year, I should probably clean it. I was not having any issues with the machine but I just wanted to maintain it so it would last longer. The great thing about this product is that it is for multiple uses so I only used one third of the bottle. It was easy to use (following the directions on the label) but you do have to invest the time to do it right because it requires you to flush out the Keurig afterwards a bunch of times. It is worth the time, because I noticed that after using the cleaner the water came out faster. I also began brewing a few hours later and the coffee and tea tasted just as great as before. There was no chemical taste or smell at all. I would purchase this item again when I run out.
