Cleaned my Keurig since it was only brewing 1/2 cups and the pump was making terrible noises.
To clean, also known as the descaling process, (from the Keurig manual):
- Take all removeable parts off and wash, stick a pin or paper clip up into the exit needles to dislodge any clumps, be careful they are sharp, replace parts.
- Fill reservoir with white vinegar and brew until the add water light comes on. Leave power on and let the Keurig sit for 4 hours.
- Discard any remaining vinegar and rinse.
- Fill with fresh water and brew until vinegar is dissipated, (took me at least 10 cups).
