The water used to brew your K-cups has minerals that cause limescale to build up inside your Keurig Supreme coffee maker. Regularly descaling your K-Supreme brewer will keep it in top shape. For best results, you should use a special solution that has a safe and effective formula. This will work better than vinegar. Keep reading to learn how to descale Keurig Supreme coffee makers and get answers to other common descaling questions. Descaling Keurig Coffee Makers Why Is It Important To Descale Your K Supreme?As I wrote above, the water you use to brew your coffee contains minerals that get left behind in your K Supreme. All types of water, other than distilled water, will have minerals. That includes tap, filtered and bottled spring water. Distilled water is not recommended to use with your Keurig. These minerals are not toxic. However, if you don’t remove them, they can build up and eventually affect your Keurig’s water flow as well as the taste and temperature of your coffee. In particular, the minerals can negatively affect the heating element and other important internal parts that often come in contact with water. How Often To Descale Your Keurig SupremeYou should descale your Keurig every 3 months. This is true even if you are using a water filter. Filters cannot remove all of the calcium and magnesium from the water. These two minerals cause the limescale buildup that can only be removed by descaling. If your tap has “hard water,” meaning it contains a high level of minerals, then you should descale your brewer more often. If you are unsure if you have hard water, you can get a low-cost testing kit. Keurig Supreme, Supreme Plus and Supreme Plus SMART all have built in notifications that will alert you when it is time to descale. However, these notifications are likely triggered more by time or K Cups used rather than detecting actual mineral buildup. With that in mind, you may want to descale even if the brewer isn’t saying you need to. It is usually a good place to start when your Keurig Supreme isn’t working correctly. For example, descaling may help solve these common issues:
You will also want to descale your Keurig Supreme if you’ve stored it away or not used it for a long time without emptying the internal water tank first. Since water was left inside the machine, limescale likely built up inside while it was out of use. Can You Descale Keurig Supreme Coffee Makers With Vinegar?Keurig warns that you should not descale your Supreme with vinegar or lemon juice. White vinegar has 5-8% acetic acid. Apple cider vinegar and lemon juice have 5-6%. This can wear down metal and cause leaks. Using a DIY solution with vinegar or baking soda can void the warranty. You also don’t want a vinegar taste or smell in your cup of coffee. It is best to use a solution that contains safer types of acids that won’t cause damage or change the taste of your coffee. Keurig Descaling SolutionsKeurig makes its own descaling solution that works with all Supreme models. However, there are other popular descaling solutions sold online that you can use instead. KeurigKeurig Descaling Solution The safe formula has no odor and acts fast to remove mineral build up with gentle citric acid. Using this solution won’t cause any harm to your brewer. You can buy the solution alone or as part of a bundle with rinse pods and filters that will also help you keep your machine clean. ImpresaThe Impresa descaler is a top selling descaler. It uses citric and sulfamic acids. Both are gentle on metal and aluminum. A pack has two bottles, each enough for two uses.

However, you can also find the official Keurig solution in stores. Target sells it in store and online. You can also find the solution at Walmart and Bed Bath and Beyond. An Important Warning About Descaling Keurig Supreme BrewersMany owners of a Keurig Supreme have complained that their brewer stopped working after running a descale cycle. The issue appears to be with the thermal switch inside the machine. The back to back “brew” cycles needed to run the solution through the machine and then rinse it appear to sometimes overheat the brewer and cause the thermal switch to trip. It is also possible that during the first part of the descaling process, the brewer runs the water tank too dry instead of turning on the add water indicator and causes itself to overheat. No matter the cause, when the thermal switch trips, the brewer won’t turn on and you will need to contact support. If you haven’t done this already, you’ll want to find your serial number and register your machine for the warranty. How To Adjust The Official Descale Instructions To Reduce Overheating RiskIf you are concerned about any risk to your machine, you can try one of these modifications shared by some Supreme owners on Reddit. Option 1 is, during the rinse cycles, try filling your tank with fresh water half way instead of the max line. After the first rinse cycle, when the add water light comes on, wait 30 minutes before starting the next rinse cycle. This will give your Keurig Supreme a chance to cool down. Option 2 is begin the descale process as described below, but when the water-descaler mix is just under and inch, turn off the brewer and unplug it. Empty and rinse the water tank. Let your Supreme sit idle for a minute. Plug the unit in again and the descale alert should reappear. Add fresh water to the tank and complete the rinse cycles to finish descaling. How To Fix Your K Supreme If It Fails After DescalingIf your Keurig Supreme won’t start after descaling, I would strongly recommend calling Keurig support. They will be able to help you, especially if your machine is within its one year warranty period. As shown in the video below, some people have figured out a way to open up the brewer and reset the thermal switch. This may be advanced for most people. It also may void your warranty. Again, I think it is best to contact Keurig support first.

How To Reset Keurig Descale Light That Stays On After CleaningThe descale alert should reset automatically if you followed the instructions all the way through without interruption.
