Can you descale a Keurig coffee maker with white vinegar?

A Keurig coffee maker can be descaled using white vinegar, which removes a majority of the limescale that builds up inside the machine. Limescale typically builds up inside a coffee maker's heating elements and tubing after repeated use, increasing the energy needed to heat it up.

A coffee maker with lots of scale buildup runs a risk of being energy-inefficient, reducing the life of its internal motor. After cleaning a Keurig coffee maker using white vinegar, a thorough rinsing with water is needed to remove any leftover smell. Any trace of vinegar left can affect the taste and smell of coffee brewed in the machine.
