Step 2: Descale Your Keurig
Mineral deposits can clog the internal parts, causing incomplete brews. Use a descaling solution or a mixture of white vinegar and water to clean the machine.

Clogged needles or brew paths can restrict water flow. Carefully clean the needle with a paperclip or a needle cleaning tool, ensuring no debris blocks the water passage.
- Turn off and unplug the machine.
