Descale Your Keurig 2.0 by Running a Cleaning Cycle with Descaling Solution

Descaling removes mineral buildup inside your Keurig 2.0 that accumulates from water, especially in hard-water areas. The machine has a built-in descaling mode that walks you through the process using a commercial descaling solution—you do not need to take the brewer apart or use vinegar. The whole process takes about 30 minutes and should happen every three to six months, depending on your water hardness.

You will need a bottle of Keurig Descaling Solution (the official brand works best, though some third-party solutions work too), an empty mug or container, and access to your Keurig's water reservoir. If you have never descaled before, the machine may prompt you to do so when you turn it on.

Key Takeaways

  • Fill the water reservoir with descaling solution mixed with water according to the bottle's instructions, then place an empty mug under the brew head.
  • Press and hold the Menu and Brew buttons together for three seconds to enter Descale Mode, which will be confirmed by a light on the display.
  • Run the descaling cycle by pressing Brew repeatedly until the reservoir is empty, which takes about 15 minutes and produces hot liquid you must discard.
  • Refill the reservoir with fresh water only and run the rinse cycle twice to flush out all descaling solution before brewing coffee again.
  • Descale every three to six months to prevent clogs and keep your Keurig heating water to the correct temperature.

What You Need Before You Start

Gather these items before you begin: a bottle of Keurig Descaling Solution (available at most grocery stores, online retailers, and big-box stores), a large empty mug or container that holds at least 10 ounces, and your Keurig 2.0 brewer. Do not use vinegar or homemade solutions—they can damage the internal heating element and void your warranty.

Check the descaling solution bottle for the exact mixing ratio. Most Keurig solutions require you to fill the reservoir halfway with solution and halfway with water, but some brands differ. Read the label before you pour. You will also want a sink or drain nearby because the liquid that comes out during descaling is hot and should not be consumed.

Step 1: Prepare the Machine and Fill the Reservoir

Empty the water reservoir completely and remove any K-Cup or reusable pod from the brew head. Rinse the reservoir under running water to clear out any old water or debris, then fill it with the descaling solution and water mixture according to the bottle's instructions. Most bottles tell you to use equal parts solution and water.

Place the empty mug or container under the brew head to catch the descaling liquid. Make sure the mug is large enough—you will be running several cycles and the liquid will be hot. Do not use a mug you plan to drink from later.

Step 2: Enter Descale Mode on Your Keurig 2.0

Press and hold the Menu button and the Brew button at the same time for three seconds. The display will show "Descale" and a light will turn on to confirm you are in Descale Mode. If the display does not change, release the buttons and try again—hold them for the full three seconds without letting go early.

Once Descale Mode is active, the machine is ready to run the cleaning cycle. You cannot brew coffee normally while in this mode, and the machine will not heat water to drinking temperature. This is intentional and keeps you safe from accidentally consuming descaling solution.

Step 3: Run the Descaling Cycle

Press the Brew button to start the cycle. Hot descaling solution will flow into your mug. When the flow stops, the machine is pausing—press Brew again to continue. Keep pressing Brew each time the flow stops until the reservoir is completely empty. This process takes about 15 minutes and you will press Brew roughly 5 to 7 times.

Watch the reservoir as you go. When it is empty, the machine will beep or the display will change to signal that the descaling cycle is complete. Empty the mug into the sink and do not drink any of this liquid.

Step 4: Rinse the Machine Twice with Fresh Water

Remove the reservoir and rinse it thoroughly under running water. Fill it completely with fresh water only—no solution. Place the empty mug back under the brew head and press Brew repeatedly, just as you did during descaling, until the reservoir is empty. This first rinse removes most of the descaling solution.

Refill the reservoir with fresh water again and repeat the rinse cycle a second time. Two rinses are important because leftover descaling solution can affect the taste of your coffee and may damage the heating element if left inside. Empty the mug after each rinse and discard the water.

Step 5: Exit Descale Mode and Brew Normally

Press and hold the Menu and Brew buttons together for three seconds again to exit Descale Mode. The display will return to normal and the Descale light will turn off. Your Keurig 2.0 is now ready to brew coffee.

Insert a K-Cup or reusable pod, place a mug under the brew head, and press Brew to make sure everything works. The first cup may taste slightly different as the last traces of solution clear out—this is normal. If you notice any unusual taste or the machine does not heat water properly, run one more fresh-water rinse cycle.

Common Mistakes to Avoid

Do not use vinegar or other household cleaners. They corrode the internal parts and are not designed for the Keurig's heating system. Stick to Keurig Descaling Solution or a solution specifically labeled for Keurig machines.

Do not skip the rinse cycles. Descaling solution left inside will make your coffee taste bitter and can clog the machine faster next time. Two full fresh-water rinses are the minimum. If you are unsure whether you rinsed enough, run a third cycle—it takes only a few minutes and is safer than guessing.

Do not try to brew coffee while in Descale Mode. The machine will not heat the water to the right temperature and you could accidentally drink descaling solution. Always exit Descale Mode before brewing a regular cup.

Frequently Asked Questions

How often should I descale my Keurig 2.0?

Descale every three to six months depending on your water hardness. If you have very hard water (high mineral content), descale every three months. If your water is soft, every six months is usually enough. You can also descale more often if you notice slower brewing or weaker coffee.

Can I use vinegar instead of Keurig Descaling Solution?

No. Vinegar damages the heating element and internal seals over time and will void your warranty. Keurig Descaling Solution is designed to dissolve mineral deposits without harming the machine. It costs about $5 to $7 per bottle and lasts for one descaling cycle.

What if my Keurig 2.0 will not enter Descale Mode?

Make sure you are pressing Menu and Brew at the same time and holding for the full three seconds. If the display still does not show "Descale," unplug the machine for 30 seconds, plug it back in, and try again. If it still does not work, contact Keurig customer service—the machine may need repair.

Can I use the machine right after descaling or should I wait?

You can brew when ready after the second rinse cycle, but let the machine sit for a few minutes if you prefer. The water will be hot and ready to brew right away. Brew one test cup to make sure the taste is normal before making coffee you plan to drink.

What should I do if the descaling solution tastes like it is still in the machine after I brew?

Run a third fresh-water rinse cycle. Place an empty mug under the brew head, fill the reservoir with fresh water, and press Brew repeatedly until the reservoir is empty. Discard this water and try brewing again. If the taste persists, run a fourth rinse.
