Attention Keurig Owners: Here’s How to Easily Descale Your Coffee Maker

Hello, Challenger! Are you one of those coffee lovers who can’t start your day without a fresh, hot brew from your beloved Keurig? We feel you. However, over time, your coffee maker may become clogged with mineral buildup, causing a significant drop in performance and taste. That’s why it’s essential to learn how to descale a Keurig properly.

Descaling—a simple process of cleaning out the mineral build-up—is crucial for maintaining the functionality and longevity of your machine. It ensures that your Keurig continues to produce fresh and flavorful coffee, tea, and other beverages.

In this comprehensive guide, we’ll walk you through everything you need to know about descaling your Keurig. From understanding the importance of descaling to a step-by-step guide on how to do it, we’ve got you covered.

The Importance of Descaling a Keurig Machine:

Over time, minerals such as calcium and lime from your water source can build up in your Keurig. This mineral buildup can impact the device’s performance and affect the quality of your coffee. Descaling your Keurig will remove any mineral buildup from the internal plumbing system and heating element of the machine.

Additionally, descaling your Keurig will extend the lifespan of your coffee maker. The build-up of minerals can cause the machine’s internal parts to corrode, which can ultimately lead to a breakdown of the Keurig.

Here are some clear signs that your Keurig is due for a cleaning:

Signs Your Keurig Needs Descaling
Your Keurig takes longer than usual to brew a cup of coffee.
The coffee has an odd taste or unusual coloring.
Your Keurig makes a strange noise when brewing coffee.
The device’s water flow is slower than normal.

What You Need to Descale Your Keurig:

Before starting the descaling process, gather the following materials:

  • A Keurig-compatible water filter.
  • Clean cloth or towel.
  • A large cup or mug.

Step-by-Step Guide on How to Descale a Keurig:

Follow these simple steps to descale your Keurig machine:

Step 1: Prepare Your Keurig Coffee Maker

Start by switching off your Keurig machine and unplugging it from its power source.

Step 2: Empty the Water Reservoir

Remove the water reservoir, empty out any remaining water, and rinse it out with clean water.

Step 3: Insert a Keurig-compatible Water Filter in the Reservoir

Insert the Keurig-compatible water filter into the reservoir, making sure it is flush with the bottom of the water tank.

Step 4: Pour Descaling Solution into the Reservoir

Next, take your Keurig descaling solution, vinegar or citric acid, and pour it into the reservoir tank. Please follow the manufacturer’s instructions for mixing proportions.

Step 5: Place the Reservoir Back in the Keurig Machine

Once you’ve added the descaling solution, place the water tank back into the Keurig machine. Make sure the water reservoir is firmly in place.

Step 6: Run Two Brew Cycles

Now you are ready to start the descaling process! Place a large cup or mug underneath the dispenser and run a brew cycle without a K-cup. Dispose of the water when finished.

Repeat this process for a second time. This will ensure that all the descaling solution has been flushed from the device completely.

Step 7: Rinse Your Keurig Machine

After completing the two brew cycles, remove the water tank and rinse it with clean water. Then, run multiple cycles of just water through your Keurig coffee machine until the water runs clear.

Your Keurig is now clean and ready to brew your next cup of coffee!
