Step 2: Descale Your Keurig
- Pour the descaling solution into the water reservoir according to the instructions on the descaling kit.
- Run a brew cycle without a K-Cup, allowing the solution to pass through the system.
- Repeat with fresh water to rinse out any remaining descaling solution.
Step 3: Clean the Needle and Brew Path
Use a rinse or cleaning pod, or gently clean the needle with a paperclip or a Keurig cleaning tool to remove any coffee grounds or residue blocking the brew.
Step 4: Use a Reusable Filter (Optional)
If you brew with ground coffee often, consider using a My K-Cup reusable filter. This reduces residue buildup and allows you to control the quality of your coffee grounds.
Step 5: Test Brew and Adjust
After cleaning, brew a cup with fresh water to check if the taste has improved. Repeat descaling every 3-6 months to prevent mineral buildup and maintain optimal flavor.
