A:Answer Thank you for your question. The complete Use and Care Guide with detailed descaling instructions can be found on the Support page of the Keurig website. We have included them below as well:
STEP 1: Prepare the Brewer
Pour the entire bottle of Keurig Descaling Solution into an empty water reservoir. Then fill the empty bottle with water and pour into the water reservoir. Do not insert a K-Cup pod. Place a large mug on the drip tray.
STEP 2: Descale the Brewer
To activate Descale Mode, begin with the brewer plugged in and powered off, then press and hold the 8oz and 12oz buttons together for 3 seconds. When flashing, press the 12oz button to start the descaling process. Once the brew is complete, pour the hot liquid into the sink. Continue to brew until the ADD WATER light illuminates.
STEP 3: Fresh Water Rinse
Empty the water reservoir, rinse the tank, and refill to the MAX FILL line with fresh water. When flashing, press the 12oz button to start the rinsing process. Once the brew is complete, pour the hot liquid into the sink. Continue to brew 12oz until the DESCALE notification turns off. The brewer has now exited Descale Mode and will be ready for use!
