Empty the water reservoir
Remove the K-Cup pod holder (needle/holder assembly) if your model allows
Fill the reservoir with descaling solution (Keurig Descaling Solution) to the fill line
Add fresh water to the reservoir if your descaling solution requires dilution (follow the label)
Place a large mug or container on the drip tray
Start a brew cycle without a K-Cup pod (use the largest size setting)
Pour out the mug contents after each cycle
Continue running brew cycles until the reservoir is empty
Let the brewer sit for 30 minutes (or follow the descaling solution instructions)
Refill the reservoir with fresh water
Run additional brew cycles without a K-Cup until the reservoir is empty
Repeat with fresh water if needed until no descaling solution smell remains
Reinstall any removed parts (if applicable)
Run one final brew cycle with water only (optional, if your model recommends rinsing)
Wipe down the exterior and drip tray
Reassemble and run a few water-only brews if you notice any residue or taste
