When you first get your Keurig, the excitement of quick, delicious coffee at the push of a button is undeniable. But over time, you might notice that your beloved coffee machine doesn’t produce that rich taste as it used to, or it operates slower than before. This is often a sign that your Keurig needs descaling, a crucial maintenance step that many owners overlook.

Understanding what descaling is, why it’s necessary, and how to properly execute the process can ensure your Keurig continues to provide that perfect cup of coffee every morning.

What is Descaling?

Descaling is the process of removing mineral buildup, commonly known as limescale, from the inner workings of your coffee machine. Water, especially hard water, contains minerals like calcium and magnesium that can deposit on surfaces and components within your Keurig, affecting its performance and the taste of your coffee.

Signs Your Keurig Needs Descaling

Your Keurig will often tell you when it’s time for a descale. Here are some telltale signs:

  • Slower Brewing Times: If your coffee is taking longer to brew, it could be due to limescale buildup.
  • Strange Noises: Unusual sounds during brewing can indicate that water flow is being obstructed by scale.
  • Poor Coffee Taste: If your coffee doesn’t taste quite right, scaling could be affecting the brewing temperature and water flow.
  • Error Messages: Some Keurig models will display a descaling alert when it’s time for maintenance.

The Impact of Scaling on Your Keurig

Scaling can have several negative effects on your Keurig, including:

  • Reduced Heating Efficiency: Limescale acts as an insulator, making it harder for your Keurig to heat water to the optimal temperature for brewing coffee.
  • Clogged Water Lines: Mineral deposits can block the tiny tubes and needles in your machine, leading to malfunctions or complete failure.
  • Shortened Lifespan: Consistent scaling without proper descaling can lead to irreversible damage and a shorter lifespan for your Keurig.

Step-by-Step Guide to Descaling Your Keurig

Descaling your Keurig is a straightforward process that can be done in a few simple steps:

  1. Prepare the Machine:
  2. Turn off your Keurig and unplug it from the power outlet.
  3. Remove any K-cup pods, the water reservoir, and if possible, the drip tray and K-cup holder.

  4. Fill the Reservoir with Descaling Solution:

  5. Fill the water reservoir with a Keurig descaling solution or a homemade mixture of equal parts white vinegar and water.
  6. Place the reservoir back onto the machine.

  7. Run the Descaling Cycle:

  8. Power on your Keurig and run a brew cycle without a K-cup pod, dispensing the descaling solution into a mug or container.
  9. Repeat this process until the reservoir is empty, discarding the contents of the mug after each cycle.

  10. Let the Machine Sit:

  11. If your Keurig has a descaling mode, follow the instructions provided in the manual.
  12. If not, after emptying the reservoir, let the machine sit for at least 30 minutes with the power on to allow the solution to work on the scale buildup.

  13. Rinse Thoroughly:

  14. After the descaling solution has done its job, refill the reservoir with fresh water.
  15. Run multiple brew cycles with just water to rinse out any remaining descaling solution.
  16. Continue this process until you can no longer smell vinegar or descaling solution.

  17. Reassemble and Enjoy:

  18. Once the machine is thoroughly rinsed, reassemble any parts you removed.
  19. Your Keurig is now ready to brew fresh, delicious coffee once again.

Frequency of Descaling

The frequency of descaling your Keurig depends on several factors:

  • Water Hardness: The harder your water, the more often you’ll need to descale.
  • Usage: Heavy use will require more frequent descaling.
  • Keurig Recommendations: Follow the manufacturer’s guidelines, which typically suggest descaling every 3 to 6 months.

Preventive Measures and Best Practices

To minimize the need for frequent descaling, consider these tips:

  • Use Filtered Water: This can reduce the mineral content and slow down scale buildup.
  • Regular Cleaning: Regularly clean removable parts and wipe down your machine.
  • Descale Promptly: Don’t wait for signs of scaling; descale regularly as preventive maintenance.


Regular descaling is an essential part of Keurig maintenance that ensures your coffee machine operates efficiently and continues to produce great-tasting coffee. By incorporating descaling into your routine, you can extend the life of your Keurig and enjoy your coffee at its best.


Q: Can I use any vinegar for descaling?

Q: How do I know if my water is hard?
A: You can purchase a water hardness test kit or check with your local water utility.

Q: Can descaling solve all Keurig performance issues?
A: While descaling can resolve many issues related to scale buildup, some problems may require additional troubleshooting or professional repair.
