What is Descaling a Keurig Coffee Maker: A Quick Guide to Maintaining Fresh Brews

Keurig coffee makers have revolutionized the way we enjoy our morning brew. With just a push of a button, we can have a piping hot cup of coffee ready in seconds. However, like any other appliance, Keurig coffee makers require regular maintenance to ensure they continue to produce fresh and flavorful coffee. One essential maintenance task is descaling. In this article, I will guide you through the process of descaling your Keurig coffee maker, so you can continue to enjoy the perfect cup of coffee every morning.

What is Descaling?

Descaling is the process of removing mineral deposits, or scale, from the inner workings of your Keurig coffee maker. Over time, minerals from the water you use to brew your coffee can build up and clog various components of the machine. This can lead to slower brewing times, decreased water flow, and even a less flavorful cup of coffee. Descaling is necessary to remove these mineral deposits and keep your coffee maker running smoothly.

Why is Descaling Necessary?

As mentioned earlier, mineral deposits can accumulate in the inner parts of your Keurig coffee maker over time. If left untreated, these deposits can affect the performance and longevity of your machine. Descaling not only ensures that your coffee maker functions optimally but also helps in maintaining the quality and taste of your coffee.

When Should You Descale Your Keurig Coffee Maker?

The frequency of descaling depends on the hardness of your water and how often you use your coffee maker. If you have hard water, which contains a higher concentration of minerals, you may need to descale more frequently. On average, it is recommended to descale your Keurig coffee maker every 3-6 months. However, if you notice any signs of scaling or experience a decline in performance, it may be wise to descale sooner.

What You Will Need

Before we dive into the descaling process, let’s gather the necessary supplies:

1. Descaling Solution: You can purchase a descaling solution specifically formulated for Keurig coffee makers from the manufacturer or your local store. Alternatively, you can opt for a homemade solution using equal parts of white vinegar and water.
2. Fresh Water: You will need clean, fresh water for rinsing.
3. A Mug or Bowl: This is needed to collect the descaling solution and water during the process.
4. A Microfiber Cloth or Sponge: This will be used to clean the external surfaces of your coffee maker.

The Descaling Process

Now that you have the required supplies, it’s time to begin the descaling process. Follow these steps carefully:

Step 1: Prepare Your Coffee Maker

Start by switching off your Keurig coffee maker and unplugging it from the power source. Give it a few minutes to cool down before proceeding to the next step.

Step 2: Empty the Water Reservoir and Remove Any Remaining Pods

Lift the lid of the water reservoir and remove any remaining water. Make sure to discard any used pods or K-cups if present. It is crucial to work with a clean and empty machine during the descaling process.

Step 3: Mix the Descaling Solution

If you are using a descaling solution, follow the instructions provided to mix it with water. If you have opted for the homemade solution, mix equal parts of white vinegar and water. The amount of solution you need will vary depending on your coffee maker’s model, so refer to the user manual for guidance.

Step 4: Fill the Water Reservoir

Pour the prepared descaling solution into the water reservoir of your Keurig coffee maker. Take care not to overfill it. Ensure that all the solution is poured and none of it is wasted.

Step 5: Start the Brew Cycle

Place a mug or bowl on the drip tray to collect the descaling solution. Then, start the brew cycle without inserting any coffee pod. This will allow the descaling solution to pass through the internal components of the coffee maker and remove the mineral deposits.

Step 6: Repeat and Rinse

Once the brew cycle is complete, empty the mug or bowl and repeat the process with the remaining descaling solution. This ensures that all parts of the machine are thoroughly descaled.

After the second brew cycle, empty the water reservoir and thoroughly rinse it with fresh water. Repeat this rinsing process until any residual descaling solution is completely flushed out.

Step 7: Clean External Surfaces

While descaling primarily focuses on the internal components, it is essential to keep the external surfaces of your Keurig coffee maker clean as well. Use a microfiber cloth or sponge dampened with water to wipe away any buildup or stains. Avoid using abrasive cleaners or scrubbing pads that may damage the machine’s finish.

Step 8: Reassemble and Brew

Once you have cleaned the external surfaces, it’s time to reassemble your Keurig coffee maker. Fill the water reservoir with fresh water and place a clean mug on the drip tray. Run a few brew cycles without any coffee pod to ensure all traces of descaling solution and vinegar are eliminated. This step is crucial as it ensures that your next cup of coffee is free from any residual taste or odor.

Congratulations! You have successfully descaled your Keurig coffee maker. By performing this important maintenance task regularly, you can ensure the longevity of your machine and continue to enjoy a flavorful cup of coffee every time.


Descaling your Keurig coffee maker is a simple yet crucial maintenance task that should not be overlooked. By removing mineral deposits and scale buildup, you can keep your machine running smoothly and your coffee tasting delicious. Remember to descale every few months or as needed, depending on the water hardness and usage frequency. With a properly descaled Keurig coffee maker, you can enjoy the ultimate coffee brewing experience each morning.
