Worked like a charm when the Clean light kept blinking on my Ninja Coffee Bar Single-Serve System with XL Ninja Hot & Cold 22 oz. Multi-Serve Tumbler and Recipe Book (CF112). You may have to run more water-only cycles than the instructions state--it'll depend on your machine.

Specific notes for use with the Ninja:
-Don't take the water bin off when you're filling it with water before running through your clean/flush cycles. This was someone's tip I read on Amazon and I'm thinking it helped. I believe this has something to do w/ the flushing part of the process. I just put water from the sink into a cup, then poured it in the tank.
-It's gonna take a long time--I got through like, 5 episodes of Grey's Anatomy while constantly getting back up before the Clean light finally stopped blinking. I read other reviews that stated they were having issues with the light turning off even after hours of cycles, so I counted myself lucky

After non stop problems with my Ninja coffee bar and cleaning light coming on, I called Ninja, and they sent me this cleaner - problem solved. Apparently, I have terrible water, and vinegar wasn't strong enough.
I just follow the direction and run the cleaning cycle a few times using tge same water. Ic i run it through once, the clean light is back on in two weeks. After find this product on Amazon and reading another review, I niw run the clean cycle 3-4 times, using the same water and the clean liggr will stay off for 6-7 weeks. Ninja customer service was great, and I live this cleaner. Wish I knew about before the 4 other coffee makers just stopped brewing!

Used Vinegar every 2 weeks, before I had problems. After a few weeks of Clean Light problems, I did the Ninja enhanced cleaning method with Full Circle one time as per full circle instructions, and the coffee bar now works like new again. I did use a paper filter, and run the same solution through 2 or 3 times. I had enough calcium deposits in the filter, that it was hard for the water to run though it. My Ninja is now working as new.

Used for the first time in my Ninja Coffee Bar...amazed by the results! This whole time I was using white vinegar, and it always came out clean..well it was illuminating the "CLEAN ME" light more and more often so after seeing this stuff on the manufacturer's website, bought it here (it was cheaper through Amazon) and used it....wow. Went in clean and clear, came out milky white with black solids on the bottom of the carafe. I was blown away!!!

I installed a filter into the basket and ran it through as I were making coffee. Using the initial mixture over and over again, that was now hot, I repeated the process three more times and each time installed a new filter. What I found was the amount of residue was much greater with the second & third cycle than the 1st and 4th. What this tells me is that using the product as recommended will yield only marginal results. So far so good after one month.
For future cleans, I'm going to repeat this process and check the results are replicated.

The Full Circle Coffee and Expresso Machine descaler is exactly as advertised. We have used it twice and are very happy with the results. We have a Ninja Coffee Machine & it was needing to be cleaned often when we used vinegar. Now it goes quite awhile between cleanings. We just ordered more of this product.

Love this stuff. Works great with my Ninja. Just pour the entire bottle into the water resovoir, then fill the resovoir to the fill line with cold tap water, and run the machine through the clean cycle. When cleaning is done, fill the resovoir again with cold tap water and run another clean cycle through the machine, efficively flushing the system. Boom! Delicious tasting coffee for another three months. Love it! And no funky vinegar taste...

I read a previous review that the product worked on Ninja coffee bar but after using two bottles, the clean light kept blinking. I had to use white vinegar to completely clean the machine so that the clean light would reset. I would not recommend for the Ninja coffee bar, as it does not work. Save your money and time and use white vinegar.

I have an Illy espresso maker that needs cleaning about every 6 months. I've used crystal packets in the past, but they don't dissolve quickly, and there's always some crystals that never dissolve. This translate to a less than efficient coffee maker cleaning process. This liquid works tremendously well to get my espresso maker back to working.

I’ve been a big believer in just using vinegar to clean coffee machines. My coffee maker has a light to let me know when it needs cleaning. The use of vinegar only made the light turn off once.
I used this cleaner and the light turned off after the first time.
