Cleans my kettles even without having to use boiling water. This is very strong and effective. I still rinse my kettles with boiling water after cleaning just to be safe. Worth it and value for moneyWorked well first few times.I received the Goo Gone coffee maker cleaner just in time! The descale light came on the next morning. It recommends 1 oz of cleaner to 16 oz of water. I used 2 oz (1/4 cup) to 32 oz of water, which means I get 4 cleanings out of this 8 oz bottle!! What a deal!!I typically run 3-4 6oz cycles thru the Keurig and then I let it sit and walk away for a few hours. I come back and finish running the rest of the cleaning solution thru the Keurig until it's empty. Then I do as many cycles of plain, clean water until I can no longer taste any of the solution (1 to 2 reservoirs full). Let me just tell you how much crud came out of my Keurig!! We have fairly hard water and I think it got everything out from the last 2 years of having the coffee maker! I've tried other commercial cleaners including the Keurig brand, I've tried white vinegar, as well. I really, really like the Goo Gone the best and will be ordering more when I finally run out of this bottle.I received this at a reduced cost in exchange for my honest and unbiased review.I am so glad I found this product, it works so well on the machine, even used it on the ice maker. Worked great!I used this on my espresso maker to clean the lime build up in the holding tank and the system lines. it worked perfectly. And i have enough left to last me for a couple of years.Monthly cleaning with Goo Gone keeps our coffee tasting fresh and always hot.I love this product it doesn’t smell and cleans my coffee pot better than any other product I’ve usedFor years, I relied on white vinegar to clean my coffee pots - and I never enjoyed coffee for a few days after even though I rinsed profusely after cleaning. But This Stuff is GREAT! I forgot that I cleaned the coffee maker yesterday - my husband reminded me after I commented on how good the coffee was this morning. Also cleaned my Keurig with the same results. Sparkling clean machine with delicious coffee - no lingering vinegar odor. Just follow the directions and be sure to run clear water through a couple times as directed. Good product!Have no complaints. Besides removing adhesive it also removes liquid rubber which I had splattered on the paint job of my bike. It easily removed the liquid rubber from the paint and did not harm the paint.Have used googone sticker remover before but never knew they made a coffee machine cleaner as well. I was looking for a cleaner for my espresso machine and my Tassimo machine so gave the googone product a try. The product seems to works well as it removed quite a bit of "crap" from both my machines when I used it. After cleaning it seemed that both my machines had a better, more consistent water flow than prior to the cleaning.I am happy with the product and would buy again for my future coffee machine cleaning needs.Just use vinegar. Way cheaper and did the same job if not better than this solutionDécalcifierI used it in my single serve brewer and it worked well
