Empty and Clean the Water Reservoir

Remove the water reservoir and empty any remaining water. Wash it with warm, soapy water, rinse thoroughly, and dry with a clean cloth. Refill with fresh water for the descaling process.

Run a Descaling Cycle

  1. Fill the water reservoir with descaling solution or a mixture of equal parts water and vinegar.
  2. Place a large container or cup under the brew head.
  3. Run a brew cycle without a pod, allowing the solution to pass through the machine.
  4. Repeat until the reservoir is empty.

Flush with Water

Fill the reservoir with fresh water and run several brew cycles to rinse out any residual descaling solution or vinegar. This ensures your coffee won’t taste vinegary or chemical.

Clean Removable Parts and Exterior

  • Wash the drip tray, pod holder, and any removable parts with warm, soapy water.
  • Wipe the exterior of your Keurig K-Duo with a damp cloth to keep it looking tidy.
