Caring For Your Brewer Regular cleaning keeps your brewer running smoothly. Always be sure to turn off and unplug your brewer before cleaning. Brewer Exterior Keep your Keurig® brewer looking its best by cleaning the exterior from time to time. Just clean with a damp, soapy, lint-free, nonabrasive cloth. Never immerse the brewer in water or other liquids. Drip Tray The drip tray can hold up to 8 ounces of overflow and should be emptied and cleaned occasionally.
