Real Simple's Editorial Guidelines Updated on June 2, 2020 Share Tweet Pin Email Keurig machines are life-changing appliances for many. Caffeine with the touch of a button—no filters to fuss with, no coffee grounds to clean up. What could be simpler? Single-serve coffee makers like the Keurig are so hands-off that it's easy to forget that they do require some upkeep, particularly when it comes to cleaning. Keurigs (and all drip coffee machines, for that matter) can harbor harmful bacteria and mineral buildup in their inner workings. This can affect the machine's performance, yes, but failing to clean—also known as "descale"—your coffee maker is unsafe. So if your Keurig hasn't been performing its best, your coffee tastes off, or you can't remember the last time you cleaned it, it's definitely time to learn how to descale a Keurig. But where to begin with so many moving parts? We asked the experts at Keurig how to clean the machine in a flash. Below, find out how to get it sparkling clean and working better with the one household item you always have on hand: White vinegar. The process will take a few hours, so it's the perfect rainy day (or quarantine) activity to help you get back to better tasting coffee. Here's how to clean a Keurig in four simple steps. How to Make the Perfect Pour-Over Coffee at Home 01 of 04 Empty the Reservoir Keurig Turn off your Keurig. Fill the machine to the maximum line with white vinegar. Note: don't dilute it with water. Make sure to use only pure, white vinegar or Keurig Cleaning Solution ($27 for a 3-Month Brewer Maintenance Kit; amazon.com). 02 of 04 Run the Coffee Maker Until the Reservoir Is Empty Pexels Place a mug on the drip tray, turn on the Keurig, and lift the handle to make sure there isn't a pod inside. Select the largest cup setting to start cleaning the machine. Empty the hot contents in the mug and repeat this process until "Add Water" lights up. 03 of 04 Rinse With Water Pexels Let the coffee maker stand for at least four hours after the "Add Water" indicator appears (with the power on), then remove the reservoir and rinse it with water to remove any remaining vinegar. 04 of 04 Fill With Water to Wash Out the White Vinegar Pexels Fill the reservoir with fresh water to the max fill line, place the section back in the machine, and run the largest cup setting until the reservoir empties. And that's all there is to it! Descale your Keurig every three to six months to keep the coffee maker running efficiently. Was this page helpful? Thanks for your feedback! Tell us why! Other Submit
