Cleaning your Keurig with vinegar is a great way to keep it running smoothly. You can start by filling the reservoir with a mix of equal parts water and white vinegar. Run a brewing cycle without a K-Cup to let the solution clean the inside. You might run a few cycles with just water afterward to rinse it thoroughly.
