What is Descaling?

Descaling is the process of removing mineral deposits and other buildup from your Keurig machine. Over time, the water you use for brewing coffee can leave behind minerals such as calcium and lime, as well as coffee residue, which can affect the performance and taste of your coffee. Descaling your Keurig machine regularly, ideally every 3-6 months, can help remove these deposits and keep your machine working at its best.

Why is Descaling Important?

There are several reasons why descaling your Keurig machine is important:

Reason Description
Improved Coffee Quality Mineral buildup and coffee residue can affect the flavor of your coffee, making it taste bitter, sour, or weak. Descaling can help improve the quality and taste of your coffee.
Extended Machine Lifespan Mineral buildup can clog the internal parts of your machine, affecting its performance and even causing it to break down. Descaling can help keep your machine working efficiently and extend its lifespan.
Preventative Maintenance Regular descaling can help prevent issues such as leaks, clogs, and malfunctioning, which can be costly to repair or even require a replacement.

How to Know When it’s Time to Descale Your Keurig Machine

Here are some signs that your Keurig machine needs to be descaled:

  • Slow water flow
  • Incomplete brewing cycle
  • Unusual noises or vibrations
  • Strange taste or smell in your coffee
  • Blinking or flashing lights on the machine
  • Lack of steam or pressure

How to Descale Keurig Machine

Now that you understand the importance of descaling your Keurig machine, let’s dive into the step-by-step process of how to descale Keurig machines:

Step 1: Prepare Your Keurig Machine

Make sure your Keurig machine is turned off and unplugged. Remove any used K-cups or pods from the machine and empty the water reservoir. Also, make sure the brewer’s handle is closed.

Step 2: Prepare the Descaling Solution

For this step, you’ll need a bottle of Keurig descaling solution or an alternative descaling solution (such as white vinegar or citric acid). Follow the instructions on the packaging to prepare the solution, usually by mixing it with water in the reservoir. Make sure you use the right amount of solution and mix it well.

Step 3: Run the Descaling Solution through Your Keurig Machine

Place a large mug or container under the brewer to catch the descaling solution. Turn on your Keurig machine and let it run the descaling solution through its internal parts. Make sure you don’t interrupt the process or turn off the machine until it’s completely finished. Once the solution is done brewing, let the machine sit for 30 minutes to allow the solution to work its magic.

Step 4: Rinse the Machine with Water

After 30 minutes, empty the mug or container and refill the water reservoir with water. Run the machine again to rinse out any remaining solution and mineral deposits. Repeat this process until the water reservoir is empty.

Step 5: Clean the Machine’s Exterior and Accessories

Once you’re done with the descaling process, wipe the machine’s exterior with a damp cloth to remove any buildup or residue. Clean the water reservoir and other accessories such as the K-cup holder and drip tray with soap and water. Make sure they are completely dry before reassembling them back into the machine.

Step 6: Brew a Test Cup of Coffee

Before you start brewing your favorite cup of coffee, it’s always a good idea to brew a test cup first to make sure that there is no remaining descaling solution or residual taste in your coffee. Discard the test cup and brew your desired cup of coffee as usual.

Frequently Asked Questions (FAQs)

1. Can I use white vinegar to descale my Keurig machine?

Yes, white vinegar is an effective and affordable alternative to Keurig descaling solution. Follow the same instructions as you would with the descaling solution, but use a mixture of one part white vinegar to one part water instead.

2. How often do I need to descale my Keurig machine?

You should aim to descale your Keurig machine every 3-6 months, depending on how often you use it and the hardness of the water in your area.

3. Can I use tap water to make my coffee?

You can use tap water to make your coffee, but it’s important to note that the quality of your coffee can be affected by the mineral content in the water. It’s recommended to use filtered or bottled water for the best-tasting coffee.

4. Why should I use Keurig descaling solution instead of white vinegar?

Keurig descaling solution is specifically formulated to clean Keurig machines and remove mineral buildup while being safe for use on the machine’s internal parts. White vinegar may not be as effective and can potentially damage your machine if overused.

5. Can I descale my Keurig machine using lemon juice?

Lemon juice is not recommended for descaling Keurig machines as it can leave a residue that can affect the taste of your coffee and potentially damage your machine.

8. How can I prevent mineral buildup in my Keurig machine?

You can prevent mineral buildup by using filtered or bottled water instead of tap water, and by regularly descaling your Keurig machine every 3-6 months. You can also purchase Keurig’s water filter kit to further reduce mineral buildup.

9. Can I descale my Keurig machine without descaling solution or white vinegar?

It’s not recommended to descale your Keurig machine without a descaling solution or white vinegar as these are the most effective and safe options for cleaning your machine. Other alternatives may not be as effective or could potentially damage your machine.

10. Can I use the same descaling solution or white vinegar for multiple uses?

No, it’s recommended to use a fresh batch of descaling solution or white vinegar for each descaling process, as the effectiveness can decrease over time.

11. Can I use my Keurig machine while it’s descaling?

No, it’s important to let your Keurig machine go through the entire descaling process without interruption or use. Running the machine while it’s descaling can affect the process and potentially damage the machine.

12. How long does the descaling process take?

The entire descaling process can take around an hour, including the preparation and waiting time for the descaling solution to work.

13. What happens if I don’t descale my Keurig machine?

If you don’t descale your Keurig machine regularly, mineral buildup and coffee residue can accumulate and affect the quality and performance of your machine. Your coffee may taste bitter, weak, or have a strange odor. Over time, the buildup can also cause leaks, clogs, and malfunctioning, which can be costly to repair or even require a replacement.


Now that you know how to descale Keurig machines, you can enjoy a better quality and longer lifespan for your machine.
