Let the machine brew until the reservoir is empty. This will distribute the vinegar solution throughout the internal components of the machine.
* **Rinse with Water:** Once the descaling cycle is complete, empty the mug and refill the water reservoir with fresh, clean water. Run at least two full brewing cycles with water only, discarding the water after each cycle. This will rinse any remaining vinegar from the machine and ensure that your coffee doesn’t taste like vinegar.

4. Descaling Your Keurig Mini with Keurig Descaling Solution

If you prefer to use Keurig’s descaling solution, follow these instructions:
