Clean the Brew Unit and Water Reservoir
- Remove any used K-Cup pods and clean the pod holder and surrounding area with a damp cloth.
- Wash the water reservoir with warm, soapy water, then rinse thoroughly.
- Check for mineral deposits or scale at the water inlet and clean gently with a soft brush if needed.
Descale Your Keurig
- Fill the reservoir with a descaling solution or a mixture of equal parts water and white vinegar.
- Place a large mug on the drip tray.
- Run the descaling cycle without a K-Cup, letting the solution pass through the machine.
- Repeat with plain water to rinse out any remaining solution.
Run a Brew Cycle with Water Only
After descaling, run 2-3 brew cycles using only plain water to flush out residual vinegar or descaling solution. This helps ensure your coffee tastes fresh and clean.
Test and Adjust
Prepare a cup with your preferred grounds or a fresh K-Cup. Check the flavor. If it’s still off, repeat descaling or cleaning. Consider using filtered water for better taste.
