How to Descale Your Keurig (and Why It Makes a Big Difference)

If your Keurig coffee maker has slowed down, tastes off, or just doesn’t brew like it used to, it might be time to descale it.

Descaling isn’t just a maintenance task. It’s the key to preserving coffee flavor, extending your machine’s lifespan, and ensuring every Overclock roast you brew tastes exactly the way it should.

Here’s how to descale your Keurig properly, how often to do it, and what to brew afterward to celebrate your newly restored machine.

What Does “Descale” Mean?

Descaling is the process of removing mineral buildup, mostly calcium, from the internal components of your coffee machine. These minerals accumulate naturally over time from hard water and can:

• Block water flow
• Cause uneven heating
• Alter flavor
• Shorten machine life

According to the Specialty Coffee Association, limescale buildup can begin affecting brew temperature and taste after just 90 days of use, especially in hard water regions (SCA, 2022).

How to Know It’s Time to Descale Your Keurig

Watch for these signs:

• Brew takes longer than usual
• Output is less than normal
• Keurig makes sputtering or gurgling sounds
• Coffee tastes bitter, sour, or dull
• "DESCALE” alert appears (on newer models)

Even if you don’t notice symptoms, Keurig recommends descaling every 3 months to keep your brewer in top shape.

Step-by-Step: How to Descale a Keurig

✅ What You’ll Need:

• Descaling solution OR white vinegar
• Fresh water
• Ceramic mug (not paper)
• Access to a sink
• 30–45 minutes of time

⚙️ Descaling Instructions (for most models):

1. Empty the water reservoir and turn off auto-off settings
2. Pour in solution (or 1:1 mix of vinegar and water) into the reservoir
3. Run the brew cycle without a K-cup until reservoir is empty
4. Let sit for 30 minutes to allow descaling to finish
5. Refill reservoir with fresh water only
6. Run 2 full reservoirs of clean water to rinse
7. Reinsert the K-cup holder and resume normal brewing

For Keurig Plus or Keurig 2.0 models, consult the Keurig Support Guide for instructions tailored to your machine.

Troubleshooting: What If My Keurig Still Isn’t Brewing Right?

If descaling didn’t fix the issue, try:

• Cleaning the needle (use a paperclip to remove clogs)
• Replacing the water filter (every 2 months recommended)
• Power cycling the machine and running several water-only cycles
• Contacting Keurig support if your unit won’t heat or brew at all

Final Thoughts: Descaling = Better Flavor + Longer Life

If you’ve been skipping this step, you’re not alone, but it’s one of the most important things you can do for your Keurig and your taste buds.

Descale every 3 months. Use fresh Overclock roasts.
And let your coffee taste the way it was meant to.
