Ever had that moment when you’re craving a cup of coffee, and suddenly, a pesky blue light starts blinking on your Keurig Supreme? Yup, that’s your coffee machine telling you, “Hey buddy, I need a clean!”

If you’re scratching your head thinking, “Now what?”, don’t fret! I’ve got your back.

Join me on this quick journey where I’ll share the easy-peasy steps to give your Keurig Supreme a fresh start. Trust me, I’ve been through this drill with my own machine, and I’ve picked up a trick or two along the way.

So, buckle up, coffee lover! Let’s dive right in and get that machine sparkling. ☕✨

Why Is Descaling Your Keurig Regularly So Important?

You know that little chore we often skip? Cleaning our Keurig? Yeah, it might seem like a drag (I mean, who really enjoys cleaning?), but it’s super important to do it every few months.

Imagine you’ve got this shiny toy that gives you awesome coffee every day. To keep it shiny and working its best, you need to show it some love. And part of that love is cleaning it up every 3 months. This way, you make sure it stays with you, brewing perfect coffee, for a long, long time.

Now, you might be thinking: it’s just water, right? What could possibly go wrong inside?

Well, here’s a little science lesson: water has stuff in it called minerals, like calcium. Some water has more minerals, making it “hard water”. Over time, these minerals stick around inside your coffee machine and turn into something yucky called limescale.

Think of limescale as that uninvited guest who just won’t leave. Not only can it mess up your machine, but it can also end up in your coffee. Even though it’s not harmful, when it gets cozy with the heat and dampness in your coffee maker, it invites some not-so-friendly germs like fungi and bacteria. Ewww!

Now that you’re in the know, it’s high time we roll up our sleeves and get that Keurig sparkling clean. Ready? Let’s do this!

How To Descale The Keurig Supreme Coffee Maker?

Let’s tackle that Keurig clean-up! Don’t worry, it’s simpler than it sounds, and I’ll walk you through it step by step. Whether you have a basic or fancy K-Supreme model, these steps got you covered!

1. Set Up Your Keurig for Cleaning 🧹

Before anything else:

  • Empty that water tank and give it a quick rinse.
  • Using a charcoal filter? Make sure to take it out, or it’ll get all messed up.
  • Oh, and if you forgot about that old K-Cup from your last brew, now’s the time to toss it.

2. Ready the Magic Cleaning Potion: Descaling Solution 🧪

You’ll find instructions on its bottle, but here’s the quick version:

  • Pour that descaling solution into your Keurig’s water tank.
  • Add an equal amount of fresh water to it. A tip? Just refill the empty solution bottle with water, and you’ll have the perfect amount.

3. Kickstart the Cleaning Dance 🕺💃

Now, make sure your Keurig is plugged in but turned off.

  • Position a big cup (12oz or more) right under where the coffee pours out.
  • Hold down both the 8oz and 12oz buttons together for about 3 seconds.
  • You’ll see the “Descale” light pop on, and soon after, the “Brew” button will start blinking. That’s your machine saying, “Let’s do this!” Tap that button to get the party started.

4. The Descaling Shuffle 🔄

Your Keurig will start pouring out the hot cleaning solution, 12oz at a time.

  • Keep an eye on that cup because it’ll fill up quick! Empty it whenever it gets full.
  • Continue this little dance until the water tank is all out of solution. When it’s done, a light will flash saying “Add water.”

5. One Last Rinse for the Road 💦

Pull off that water tank and fill it up with fresh water.

  • Pop it back in place, and the “Brew” button will start its blinky dance again. Press it!
  • Like before, your Keurig will pour out water, 12oz at a time. Empty the cup as needed.
  • Keep doing this until all the lights on your Keurig switch off.

Your Keurig’s all fresh and sparkly now! Go on, treat yourself to a delicious cup of coffee. After that bit of work, you’ve totally earned it! 😄☕

How To Take Care Of Your Keurig And Keep It In A Good Condition?

We all want our precious coffee makers to last forever (or at least a very long time!). But for that to happen, we gotta give them a little TLC. Think of your Keurig as a treasured plant: water it, tend to it, and it’ll bloom beautifully for you every day.

1. Safety First! ⚠️

Before you do anything, remember one golden rule: Always unplug your Keurig. It’s an electric device, after all. Better safe than sorry!

2. That Helpful Charcoal Water Filter 🌊

It’s like the superhero of your Keurig because it purifies the water. So, show it some love by replacing it every two months or so. It really depends on your water type, but around 2 months is a good ballpark.

3. Water Matters 💧

Speaking of water, if you use filtered water, it’s like giving your Keurig a spa treatment. It helps reduce limescale build-up. So, go on, treat your Keurig to the good stuff!

4. Be Gentle with the Outlet Needle 📍

This little part is the one that pokes into the K-Cup and lets the water flow through. But, its tiny hole can get blocked by coffee bits or minerals. Every so often, check on it. If it looks blocked, gently use a paperclip or needle to clear it out.

5. Don’t Neglect the Removable Bits 🛁

Parts like the water reservoir love a good wash. Use warm water and a bit of dish soap. Then, rinse well and pat them dry with a cloth.

Sure, this might sound like a bunch of stuff to remember. But honestly? Most of it doesn’t need doing that often. And when you weigh it against years of heavenly coffee, it’s totally worth it.


Regularly descaling your Keurig Supreme is like taking it for a health check-up. Doing this every 3 months will keep it running smoothly. Look after your coffee-making buddy, and it’ll reward you with the most delightful cups of coffee for years and years. Cheers to that! ☕🎉
