Step 2: Clean the Brew Area and Needle
- Use a paperclip or needle to carefully clean the needle that punctures the K-Cup to remove any blockages.
- Wipe the brew area with a soft, damp cloth to remove residue or mold.
Step 3: Descale the Machine
Use a descaling solution or a mixture of equal parts white vinegar and water. Fill the water reservoir with the solution.
Run a brewing cycle without a K-Cup, then repeat with clean water to rinse thoroughly.
Step 4: Run a Cleaning Cycle with Rinse Pods
Insert a Keurig rinse pod (or a similar cleaning pod) and brew a cycle to clear out any remaining residue or oils.
This helps improve the flavor of subsequent brews.
Step 5: Use Filtered or Fresh Water for Brewing
Always use filtered or fresh water to prevent mineral deposits and ensure better taste.
Replace the water filter cartridge if your model uses one, following manufacturer instructions.
