To clean a Keurig coffee maker, start by removing and washing all removable parts such as the water reservoir, lid, drip tray, and K-Cup holder. Use warm, soapy water or place them in the dishwasher if they are dishwasher safe. Wipe down the exterior with a damp cloth and use a toothbrush to clean any hard-to- reach areas inside the machine. For the internal cleaning, descale the machine by filling the reservoir halfway with white vinegar or a Keurig descaling solution and running brew cycles into a mug until the reservoir is empty. Let the machine rest for 30 to 45 minutes to soak, then rinse thoroughly by filling the reservoir with fresh water and running multiple brew cycles to clear any vinegar or descaling solution residue. Also, clean the brewer needles with a paperclip to remove trapped grounds. Replace the water filter regularly for best results. This cleaning process should be done every three to six months depending on usage to maintain taste and functionality.
