Cleaning a Keurig coffee maker involves removing any clogs that could have accumulated in the machine. The things you will require are soap, descaling solution (or white vinegar), and water. After disassembling the machine, clean then in warm soapy water. Wipe with a dry cloth. Using a clean, dry cloth, wipe the outer surface of the coffee maker. Use vinegar to descale the water reservoir every three to six months. Once you rinse the reservoir with clean water, it will be great for use. Check out the video in our buying guide for more details.
