Cleaning the Exterior and Drip Tray
- Unplug the machine and wipe the exterior with a damp cloth to remove dust and coffee stains.
- Remove the drip tray and wash it with warm, soapy water. Dry thoroughly before reinserting.
- Check the water reservoir for mold or mineral deposits and clean with a soft cloth or sponge.
Descaling Your Keurig K-Mini
- Fill the water reservoir with a descaling solution or a mixture of equal parts water and white vinegar.
- Place a large mug on the drip tray and run a brew cycle without a K-Cup, allowing the solution to flow through.
- Repeat until the reservoir is empty, then fill with clean water and run multiple cycles to rinse out any residual descaling solution or vinegar.
Cleaning the Brew Nozzle and Internal Parts
Use a damp cloth or a soft brush to gently clean the brew nozzle to remove any mineral buildup or coffee residue. For stubborn clogs, a toothpick or a small brush can help dislodge debris.
Run a rinse cycle with clean water to clear out any remaining debris or descaling solution from internal parts.
Using Reusable Filters and Troubleshooting Common Issues
Consider using a reusable filter like the My K-Cup® Reusable Coffee Filter to prevent waste and improve flavor control. Regularly check for clogs or leaks. If the machine isn’t brewing, ensure the water reservoir is full and properly seated.
If your coffee is weak or inconsistent, clean the needle and check for blockages. For persistent issues, repeat descaling or consult troubleshooting tips.
