As an avid Keurig coffee drinker, you may have started to descale your brewer and wondered what exactly are the ingredients in Keurig descaling solution. You know you need to regularly maintain and descale your brewer, but how do you know it is safe to use and won’t affect your next coffee?


Why You Should Descale Your Keurig Regularly

It is vital that you regularly maintain and descale your Keurig machine. There are of course a few different options for descaling solutions that you can use: Keurig descaling solution, citric acid solution, lemon juice solution, white vinegar solution, and baking soda solution.

Any of these are effective mixtures to break up and dissolve the hard water mineral deposits. Pick the one that is the most convenient for you to regularly maintain and descale your brewer.


Keurig’s Descaling Solution

Keurig only recommends using its own branded descaling solution to get rid of the mineral buildup and scale in your brewer. This is repeated throughout the website and the provided user guide (Source: It is not as clear what exactly are the Keurig descaling solution ingredients, but the breakdown is citric acid, silicic acid, phosphates & bleaching agents, and water. Citric acid is the key ingredient of the solution. All of these ingredients are designed to work together to break down the lime and calcium buildup.

To descale with Keurig’s descaling solution, you will pour the entire bottle into the empty water reservoir then fill the empty bottle with water and pour it in as well. Press the brew button to begin the descaling process.

One of the main advantages of the Keurig descaling solution is the convenience of actually using it. It does not require measuring or mixing beforehand, just pour the solution and water directly into Keurig’s water reservoir and start.


Citric Acid Descaling Mixture

Citric acid is a naturally occurring substance found primarily in citrus fruits. Its mild acidity makes it an effective and safe substance to use in multiple ways, including cleaning and descaling. It is also a chelating agent, which means it can effectively bond with and remove metals (Source:

It is specifically effective as a descaling solution because the citric acid reacts with the calcium carbonate buildup allowing it to break away and be rinsed off by water. Citric acid is also one of the main ingredients of Keurig’s solution.

You can make your own citric acid solution by mixing one tablespoon of citric acid powder in one liter of hot water (two tablespoons if you would like a more acidic solution). Once the citric acid powder has completely dissolved in the water, pour the solution into the water reservoir and begin the descaling cycle like normal. This is the best way to ensure the citric acid cleans everything it needs to.


Lemon Juice Descaling Solution

You can also use lemon juice to create a descaling solution. Lemons contain citric acid and would make an effective solution similar to the citric acid solution.

This descaling solution is made with a 1-to-1 ratio of lemon juice to water, and you can use either bottled lemon juice or freshly-squeezed lemon juice. Once thoroughly mixed, the lemon juice solution is run the brew cycle to descale.

One major advantage of using a lemon juice solution is that it has a more bearable taste and smell compared to other descaling agents. It could still affect the taste of your coffee if not completely rinsed out, but not as unbearable as some other solutions.


Vinegar Descaling Solution

Another efficient option for descaling your Keurig brewer is to make and use a white vinegar solution. Distilled white vinegar is considered an efficient and inexpensive cleaner for quite a few places in your home. Its mild acidity is what makes it an efficient cleaner. Using a diluted mixture of water and white vinegar, you can easily clean up grease, grime, and dirt.

To create a vinegar solution, mix together a 1-to-1 ratio of white vinegar to the water. The easiest thing to do is to fill the water reservoir halfway with vinegar and then fill it to the top with water. This white vinegar and water combination can effectively break down the scale buildup and deposits without harming the Keurig coffee machine (plastic tubing heater, etc.). Once the cleaning cycle has been completed, you will likely need to run the rinse cycle with just water more than once to ensure there is no lingering vinegar taste or bad smell left behind. It can make your coffee taste sour or bad if not thoroughly rinsed out.

You can also use a similar white vinegar mixture as a cleaning solution to use on the outside of your Keurig coffee maker as well. Use a cloth that is damp with the mixture to wipe down the outside of your brewer, like the top, the pod holder, the mug stand, etc.


Baking Soda Descaling Solution

To create a baking soda solution, you will need to thoroughly mix 1/4 cup of baking with 1 cup of warm water. You can then pour the solution into the water tank and run a descaling cycle. You will likely need to run a rinse cycle to clear out any remaining baking soda before brewing a cup of coffee.

Baking soda is advantageous to use because it does not leave behind an aftertaste and can neutralize any pre-existing odors. Plus, like white vinegar, it is likely that you already have this readily available in your home.


How to Descale your Keurig Brewer

After you decide which descaling solution to use, these are the descaling instructions to descale one of the traditional Keurig machines:

  1. Verify that the K-cup holder is empty and turn off your brewer.
  2. Empty out the reservoir and remove the water filter.
  3. Pour the descaling solution into the open reservoir.
  4. Turn the brewer back on.
  5. Place a large mug on the drip tray and press the flashing brew button to start the brew cycle. Continue to repeat the whole process until your Keurig brewer turns on the ‘Add Water’ light.
  6. Leave the brewer on and let the machine sit for 30 minutes. Wipe down the outside of your coffee machine with a damp cloth.
  7. After resting, empty any remaining descaling solution and rinse the reservoir out. This is also an excellent time to disassemble and wash any removable parts.
  8. Fill the water tank to the max line with only water. Press the brew button. Then, you’ll need to do a minimum of at least 12 rinsing brews using the largest brew size. (Note: It’s really important not to skip the final rinsing cycle step! If any solution is left inside, it might affect the taste of your next cup.)
  9. Replace the water filter and fill the water reservoir with bottled water or fresh water.
  10. Your coffee maker is ready to brew coffee using your favorite K-cup.

If you find that your coffee still has a bad taste after descaling, you will want to repeat these steps, especially if you might still have limescale buildup from hard water or lack of descaling.
