What steps should I follow if my Keurig K'Café needs descaling?

First, fill the reservoir with a mixture of one full bottle of Keurig Descaling Solution and an equal amount of water. Place a large mug on the drip tray, then press and hold the 8oz and 12oz buttons together for 3 seconds to activate Descale Mode. Continue brewing until ADD WATER lights up, rinse thoroughly with fresh water afterwards, and brew again without descaling solution until Add Water lights stay off.
