Keeping a Keurig coffee coffee machine in good working condition is essential for getting the perfect cup of coffee every time.

This homemade coffee maker Descaling Solution works whether you have a full-size Keurig or a Keurig Mini like I do. It will even work with a regular drip coffee maker and the process to clean is pretty well the same.
In this guide, I’ll show you why descaling your Keurig machine is so important, how to whip up a homemade cleaning solution, and the simple steps to keep your coffee maker working like a dream. It’s an easy way to save money, avoid harsh chemicals, and make sure your morning coffee tastes just as good as it should for years to come.
Why Is Descaling a Keurig Important?
Over time, minerals like calcium deposits and limescale from hard tap water can build up inside the water tank and hoses inside your Keurig brewer. This buildup, known as scale, can affect how well your coffee maker works. In addition, ground coffee from coffee pods can plug things up too.
You might notice it takes longer to brew coffee, the machine gets noisier, or the taste of your coffee isn’t as good as it used to be. Ignoring scale buildup can even damage your machine in the long run.
Descaling helps remove this buildup, keeping your coffee maker working like new. Most manufacturers recommend descaling every three to six months, depending on how often you use your Keurig coffee machine and whether you have hard water. If you’ve never descaled before, don’t worry—it’s an easy process, especially when you use a homemade solution.
Ingredients for a DIY Keurig Descaling Solution
Making your own descaling solution is incredibly simple. The two most common ingredients used for this are white vinegar and lemon juice. Both are natural acids that help break down mineral buildup without damaging your machine. Here’s what you’ll need:
- White Vinegar: A household staple, white vinegar, affordable and effective at dissolving scale. Don’t worry. Your coffee won’t have a vinegar taste when you’re finished.
- Water: A few cups of water used to dilute the vinegar or lemon juice. If you have hard tap water, buying distilled water is a good idea so that you won’t be cleaning your machine with the same water that caused the buildup.
- Lemon Juice (optional): If you prefer a less pungent smell, pure lemon juice is a great alternative to vinegar. It is acidic like white vinegar and has the same cleaning and disinfecting properties.
That’s it! You don’t need any fancy or expensive products—just these basic ingredients.
How to Make a DIY Keurig Descaling Solution
The recipe is simple and easy to customize depending on what you have on hand. Here’s a basic formula:
- For Vinegar Solution: Mix equal parts white vinegar and water. For most Keurig models, you’ll need about 10 ounces of solution, so use 5 ounces of vinegar and 5 ounces of water.
- For Lemon Juice Solution: Mix one part lemon juice with two parts water. For 10 ounces, use about 3.5 ounces of lemon juice and 7 ounces of water.
Both options are effective, so choose whichever you prefer based on what’s in your pantry.
How to Use DIY Descaling Solution to Clean Your Keurig
Now that you have your descaling solution, it’s time to clean your Keurig. Follow these steps to ensure your coffee maker is descaled properly:
Step 1: Prepare the Machine
- Turn off your Keurig and unplug it for safety.
- Remove the water reservoir and rinse it out to ensure there’s no leftover coffee or debris.
- If your model has a removable drip tray or K-cup holder, take those out and clean them with warm soapy water.
Step 2: Add the Solution
- Fill the water reservoir with your homemade descaling solution.
- Reattach the reservoir to the machine and place a large mug or bowl on the drip tray to catch the liquid during the cleaning cycle.
Step 3: Start the Descaling Process
- Press the brew button to turn the machine on and begin running brew cycles without inserting a K-cup. Let the solution run through the machine as if you were brewing coffee. You may need to repeat this step multiple times until the reservoir is empty.
- For stubborn buildup, let the machine sit for 30 minutes to an hour with the solution inside before running it through.
Step 4: Rinse the Machine
- Once the solution has run through the machine, rinse the water reservoir thoroughly to remove any vinegar or lemon juice residue.
- Fill the reservoir with fresh water and run several brew cycles to flush out any remaining solution from the machine. This step is important to ensure your next cup of coffee doesn’t taste like vinegar or lemon.
Tips for Best Results
- Test for Hard Water: If you live in an area with hard water, you may need to descale your Keurig more often—about every three months. A quick way to check for hard water is to look for white spots on your dishes after washing.
- Use Filtered Water: Using filtered or distilled water in your Keurig can help reduce scale buildup and lengthen the time between descaling sessions.
- Clean Regularly: Wipe down the exterior of your machine weekly and clean the removable parts to prevent grime buildup.
Benefits of a DIY Descaling Solution
Using a homemade descaling solution has several advantages. First, it’s much more affordable than store-bought options, which can cost upwards of $10 for a single-use bottle. With vinegar or lemon juice, you’re spending just pennies per cleaning.
Second, DIY solutions are free of harsh chemicals. Many commercial cleaners contain ingredients that you may not feel comfortable using, especially if you’re trying to reduce chemical exposure in your home. Vinegar and lemon juice are natural, safe, and effective alternatives.
Lastly, making your own solution is convenient. Most people already have these ingredients at home, so you don’t have to make a special trip to the store when it’s time to descale.
Troubleshooting Common Issues
- Lingering Smell or Taste: If your coffee tastes or smells like vinegar after descaling, it’s likely because the machine wasn’t rinsed thoroughly. Run additional water-only brew cycles until the smell disappears.
- Machine Still Acting Up: If your Keurig isn’t working properly after descaling, check for clogs in the needle or water lines. You can use a paperclip to gently clean out the needle if needed.
- Error Messages: Some Keurig models have a descaling light that doesn’t turn off automatically. Refer to your machine’s manual to reset the light after completing the descaling process.
Keep Your Keurig in Top Shape
Descaling is just one part of keeping your Keurig in great condition. Regular cleaning of the drip tray, K-cup holder, and water reservoir can prevent bacteria and mold growth. Using filtered water and running a quick rinse cycle after each use can also help your machine last longer.
