- Wipe the exterior with a damp cloth to remove dust and coffee splashes.

- Use a soft brush or cloth to clean inside the brew head for thorough removal of oils and buildup.
Step 3: Descale Your Keurig
- Insert a descale solution or a mixture of equal parts water and white vinegar into the water reservoir.
- Run a brew cycle without a coffee pod, allowing the descaling solution to pass through the machine.
