How do i descale a keurig coffee maker

Listen up, coffee lovers: To ensure your Keurig maintains peak performance, it’s essential to clean the brewer regularly and descale it every three to six months. Whether you just found this out or need a refresher, we’ve laid out everything you need to know about keeping your Keurig in stellar condition.

Supplies:

  • Keurig 3-month maintenance kit (includes descaling solution, rinse pods, cleaning tablets, and filters)
  • Large ceramic mug
  • Non-abrasive cloth
  • Dish soap
  • Water

Regular Cleaning:

  1. Clean the outside of your brewer by gently wiping it down using a damp, soapy cloth.
  2. Slide out the drip tray to remove it, being careful not to spill any excess liquid that may be inside. Then, clean the drip tray and plate with a cloth.
  3. Remove the water reservoir and lid, clean both by hand, and rinse. Make sure you remove the water filter first, and don’t dry the inside of the reservoir with a cloth—this will prevent any lint from getting stuck inside. You’ll want to do this once a week.
  4. Now that you’ve cleaned the exterior and the reservoir, it’s a good idea to run a cleansing brew. To do this, refill your now-clean reservoir and put a large mug on the drip tray. Run a brew of just water—no K-Cups!—on the largest size setting. Note: You can also do this by using one of Keurig’s Rinse Pods in place of a K-Cup.

Descaling:

  1. For a deeper clean, you should descale your Keurig brewer every three to six months, depending on how often you use it. This process removes any calcium deposits inside of your machine to keep it in tip-top shape.
  2. To start the descaling process, empty your brewer’s water reservoir. Then, pour a full bottle of Keurig’s Descaling Solution into the reservoir. Fill the now-empty bottle with water, and pour that in too. Make sure the brewer doesn’t have a leftover K-Cup pod inside, place a large mug on the drip tray, and activate Descale mode.
  3. How you activate Descale mode will differ depending on your model, but for the K- Supreme model seen here, you do this by powering off the brewer and holding down the 8oz and 12oz buttons together for three seconds. Once the light starts flashing, press the brew button to start descaling. Continue to press the brew button and repeat the descaling process until the “add water” indicator lights up.
  4. Rinse the reservoir thoroughly, fill it with fresh water, and run a cleansing brew. Repeat until the Descale notification turns off.
  5. Once the Descale notification turns off, your brewer is ready for use again.

Keurig coffee machines have been a gamechanger for the at-home barista. And while they have made making our coffee, espressos, lattes, tea, and hot chocolate almost too easy, your Keurig still requires just a smidge of upkeep. They do not clean themselves, but sure would be amazing if they did that too.

Cleaning your Keurig is actually known as "descaling." No, not like skinning a fish. Rather, descaling is the process of using vinegar to break down calcium deposits that can build up inside a coffee maker over time. Not only does this achieve better-tasting coffee, it also removes harmful bacteria and mineral buildup. 

Coffee machines are a breeding ground for molds, bacteria, and germs — not exactly what you want in your coffee. We spoke to the experts to learn how to easily clean your Keurig in a few simple steps with common household items. 

How often should I clean my Keurig? 

Graham Cooke, founder of Cafe Last, recommends the descaling process be done once a week. But in reality, you only need to descale it once every two to three weeks. "We make [the once a week] suggestion because most people don't descale their coffee makers until they stop working, which has a lasting effect on the machine," says Cooke. "The idea is that if we tell someone to descale their machine once a week, they will actually do it once every two or three weeks."

In addition to the descaling process, Lopez recommends cleaning all removable parts, including the water tank and lid, coffee pod holder, drip tray once a month. 

If you're not making coffee every day, it's crucial to descale your machine at least every quarter, says Cooke. Why? Because mineral build-up in the reservoir can destroy your coffee machine by corroding your machine's internal seals and clog the machine with hard water buildup.

In general, try to keep the machine as clean as possible by checking the tray and exterior for spillage after each use. If the machine is used repeatedly on a daily basis, follow the wipe-down instructions daily.

I live in an area that has hard water. Does that change my cleaning frequency?

Hard water areas will naturally need to descale their machine more often. If you live in an area with very hard water and you are making multiple cups per day, Cooke recommends descaling your machine once a week.

Is it okay to use water in my tank that's been sitting around a while?

Use the water poured in the tank within one week, says Lopez. Never use water that has been sitting still for more than a week as it could grow mold. 

Before you store the Keurig away or go on a trip, make sure it is fully empty of water, says Shabbir Nooruddin of Coffee Brewster.

How do I clean my Keurig without vinegar or descaling solution?

Use denture tablets, says cleaning expert Abe Navas, the general manager of Emily's Maids, a house cleaning service in Dallas, Texas. 

"Even if I'm not a coffee expert, I am a cleaning expert. I developed a technique for cleaning coffee makers some years ago. It's easy and it will increase the lifespan of your machine for a long time," says Navas.

You need a denture tablet and a microfiber cloth. Put half of a denture tablet in the K-cup chamber. This will help clean any gunk build-up. Then run the machine for three to five cycles. Follow with a cycle of just water. 

Alternatively, you can use citric acid, says Nooruddin. Use one tablespoon of citric acid crystals to one gallon of water. This makes a mildly strong acid, explains Nooruddin —  it's safer to use a milder acid and descale a couple of times rather than using an excessively strong acid that could corrode the metal parts. 

Run your Keurig using several cycles of the citric acid solution, followed by several cycles of plain water. Several cycles really depends on how badly the scaling is, says Nooruddin. For very mild scaling, 2-3 cycles of citric acid solution will do the trick. For a Keurig that's been sitting in the attic for a couple of years, you'll have to run multiple cycles, recommends Nooruddin. 

"The earlier cycles will probably contain little bits of scale in the mug - ideally, you want to keep going until there is no (or tolerable) scale."

He suggests flushing with at least 2-3 cycles of water to get any remnants of citric acid out of your brewer. 

"It's always good to err on the side of caution and flush a couple of extra cycles to really get the acid out, otherwise your coffee will be a little bit funky."

Insider's takeaway

Even though a Keurig makes coffee in a snap, it is essential to spend a few moments to regularly clean it for the best coffee ever, every day. Descaling it with a simple solution of equal parts water and white vinegar will extend the life of your favorite coffee maker and keep your coffee tasting fresh.

How do I descale my Keurig with vinegar?

Run a mix of equal parts water and white vinegar through the machine. Pour the solution into the reservoir, turn on the machine, press the cycle button, and allow the solution to drain into a cup. You may need to descale your Keurig multiple times depending on how dirty it is.

How long do you leave vinegar in a Keurig to descale?

The vinegar solution can stay in the machine for about 30 minutes, but don't let it sit for more than 3 hours. Turn on the machine, place your cup in position, and run through the brew cycle until the reservoir is empty. Rise out your reservoir with clean water as you let the vinegar really tackle that mineral buildup.

Is Keurig descaling solution just vinegar?

Descaling your Keurig machine is important to keep it in great condition. While you can get specially designed descaling solutions for your machine, white vinegar is a cheaper option that's just as effective.
