Cleaning the Exterior and Removable Parts

  • Wipe the exterior with a damp, soft cloth to remove dust and coffee splashes.
  • Remove the drip tray, water reservoir, and brew basket.
  • Wash these parts with warm, soapy water; rinse thoroughly and dry.

Cleaning the Brew Head and Water Reservoir

Use a damp cloth or a soft brush to gently clean the brew head, removing any coffee residue or buildup. Wipe the inside of the water reservoir with a clean cloth. For stubborn stains, a mixture of vinegar and water can be used, but be sure to rinse thoroughly afterward.

Descaling the Keurig K-Duo

  1. Fill the water reservoir with a descaling solution or a mixture of equal parts white vinegar and water.
  2. Place a large container under the brew head.
  3. Run a brew cycle without a K-Cup, allowing the solution to pass through.
  4. Repeat with plain water to rinse out any remaining descaling solution or vinegar.

Troubleshooting Common Issues

If your Keurig isn’t brewing properly, or if coffee tastes off, regular cleaning and descaling often resolve these problems. Check for clogs, mineral buildup, or residue that can block water flow. Also, ensure all removable parts are properly seated after cleaning.
