What You Need
Clean, dry cloth
Unplug the machine: It’s a simple but important step.
Disassemble and wash removable parts: Remove the water reservoir and lid, mug stand, and also the K-cup holder. Wash these pieces in warm, soapy water and dry.
Wipe machine surface: With a clean, dry cloth (or a damp cloth where needed), wipe surface of machine. Don’t forget the area around the K-cup where coffee and tea granules may collect. Return all removable parts and plug in machine.
Descale with a vinegar rinse: Mix one half white vinegar and water to fill the water reservoir. Start the brew cycle without inserting a K-cup. Repeat until reservoir is empty, discarding the mug contents after each brewing cycle. This process will help remove lime and scale buildup. Keurig recommends descaling your brewer at least every 3-6 months depending on your water source.
Repeat rinse with water: Repeat the process using only plain water in the reservoir to remove any residual vinegar taste.
A Few Extra Notes
To reduce buildup, use bottled or spring water when brewing instead of softened water or distilled water.
Try cleaning the entry and exit needles if your system isn’t performing properly. This video from Keurig explains where to find and how to clean these parts.
Forcing air through the water line by using a straw can help dislodge debris.
