Review on USA-Made Universal Descaling Solution (2 Pack, 2 Uses Per Bottle) for Keurig, Nespresso, Delonghi, and All Single-Use Coffee & Espresso Machines by Jeff Hall

Easy to use and works great! I've tried ACV cleaning my Keurig in the past (horrible if you don't pull it out all the way and let the cream curdle). I also tried just rinsing with water, which worked for about two days. It's cheaper than the big brand for four uses, I think it has no smell (someone complained about this in a review. I don't know what they're talking about) and my Keurig brews faster and actually looks cleaner in the tank. . The solution looks a bit soapy, I followed the directions, used half a bottle, let the brew cycle run until prompted to add water (which requires a lot of emptying the cup each time), then I filled the tank with water and have did it again, then i only watered the second time, a total of 3 times according to the instructions. That's three drain cycles, not three brews. I ended up draining the remaining water, cleaning the reservoir, refilling it and having a great cup of coffee the next morning. Personally, I think anyone who has had trouble with this is either not following the instructions (I've been a teacher for almost a decade, I know this is most likely the case) or is just a troll trying to be a curmudgeon. I use my Keurig every day 2-3 times a day.
