Get the most out of your single-serve coffee maker—and the best-tasting coffee—by learning how to clean and maintain a Keurig the right way.

If your Keurig is serving up K-cup coffee goodness for more than one person, more than once a day, read on. Sure, frequent coffee drinking does have its benefits, but using your Keurig daily—without taking the time to care for or maintain it—can have some pretty icky side effects. Mold?!

Why Do You Need to Clean a Keurig?

Cleaning a Keurig is a health and safety precaution. Like any other type of coffee maker, Keurigs can grow mold if they’re not properly drained, rinsed and cleaned. Aside from keeping mold and bacteria at bay, your Keurig should be cleaned on a regular basis so that it can perform to the best of its ability. A quick clean-up will remove the mineral buildup in the machine that affects the taste and quality of the coffee being brewed. A clean Keurig produces better quality coffee.

How to Descale a Keurig

Scale forms when calcium hardens and mineral deposits dry up within water. When you fill up a Keurig with water that has a high level of mineral content, it can cause buildup in the brewer and prevent it from working correctly. It also impacts the taste of your coffee. Yuck! But don’t worry, you can descale a Keurig using a few different methods:

1. Keurig Cleaning Solution

Keurig has created and officially approved their own Keurig Descaling Solution, which is made for all Keurig 2.0 and 1.0 K-cup coffee makers. Unplug and turn off the machine, then fill the water reservoir with one part Keurig Descaling Solution and one part water. Place a coffee mug underneath the dispenser, and brew one cup of hot water. Pour the water out once it’s done, replace the mug and repeat this step until all the water is gone out of the reservoir. Rinse the water reservoir, fill it up with fresh water, brew another cup of hot water and pour it out. Voila! A descaled Keurig.

2. Vinegar and Water

Once the Keurig is turned off and unplugged, take apart the machine and wash all the removable parts. The drip tray and pod holder should be rinsed in warm, soapy water, but the K-cup filter accessory and the water reservoir can both be sanitized in the top rack of the dishwasher.

While these parts are drying, wipe down the surface of the Keurig with a damp microfiber cloth. Place all the parts back in the Keurig, and plug it in.

Fill the water reservoir to the halfway mark with white distilled vinegar, which is key to removing scale buildup, and fill the other half with water. Begin the brew cycle sans K-cup, and repeat until the entire reservoir is empty. Once the water reservoir is completely empty, repeat with plain water to flush out the vinegar taste. (Seriously, what can’t vinegar clean!?)

3. Citric Acid

Like vinegar, citric acid is great for sanitizing a Keurig, and a simple homemade way to get rid of any scale that’s formed. Prepare a citric acid solution by combining one to two tablespoons of citric acid (you can find it at spice shops or in your grocer’s canning aisle—or on Amazon) with about four cups of water, and pour it into the water reservoir. Place a coffee mug underneath the drainage spout and brew a cup of hot water, then pour it out and repeat the step. Fill up the water reservoir with water again, and keep brewing until there’s nothing left in the reservoir.

How Often Should You Clean a Keurig?

Keurig highly recommends descaling a Keurig coffee maker every three to six months. This should help prevent calcium deposits or scale buildup from occurring. The other parts of the Keurig should be given more regular attention, though. If you brew a K-cup every day, then the Keurig’s exterior, cold water reservoir, drip tray and pod holder should all be cleaned once a week. It might seem like one more chore to add to the list, but cleaning your Keurig regularly will extend the life of your machine and keep your morning (and afternoon, and evening) cup of coffee tasting fresh and strong.

Here’s where to find the best deal on K-cups, too!

How to Maintain a Keurig Between Cleanings

Keurig Rinse Pods

Keurig Rinse Pods are just the thing to keep your Keurig fresh weekly without doing a lot of work. To use, simply place a large mug on the Keurig drip tray. Lift the handle and insert a Keurig Rinse Pod, just like you would with a coffee capsule. Brew the rinse pod on the eight ounce brew setting. Remove and discard the rinse pod and the brewed rinse solution, then do an eight ounce water brew to completely rinse. Done! You’ll taste the difference, especially if you use a variety of flavored coffee and tea pods. No more cross contamination between chai teas and cinnamon roll coffee flavors.

Keurig Water Cartridge Refills

If your tap water has a lot of chlorine, it’s going to impact the taste of your coffee. Never fear. Keurig water cartridges help remove chlorine from the Keurig tank. For best results, replace the cartridge every two months or after 60 tank refills. Six water filter cartridges should last about a year, depending on how much coffee you’re brewing. And if you have a Keurig, we’re guessing you brew a lot of coffee!
