Let’s face it, because you probably never have.

Be honest, when is the last time you cleaned your trusty Keurig machine?

If you’re like most people, you probably can’t remember the last time you gave it a good once-over, or worse, you haven’t cleaned it at all.

Sorry to be the bearers of bad news here, but in addition to mineral build-up, Keurigs and drip coffee makers can harbor all sorts of harmful mold and bacteria. These not only give your coffee a weird taste, but they can also impact the lifespan of your beloved appliance—not to mention the havoc all those germs could wreak on your health!

Fortunately, Food52 has a guide you can use to finally give your Keurig the deep-clean it deserves.

First, let’s get the terminology out of the way. What you’re about to do is called “descaling,” the process of cleaning the inner workings of a coffee machine. As Food52 explains, “scale” is another term for calcium deposits, which build up in the machines over time.

To descale your Keurig, you’re going to need just three things: white vinegar or Keurig descaling solution, a large ceramic mug, and plenty of fresh water.

OK. Start by unplugging your Keurig, removing the water reservoir, and emptying it completely. Next, remove and replace the water filter (these should be changed every two months anyway).

Now, fill the water reservoir with white vinegar up to the halfway point then top it off with water. Next, plug it back in, turn it on, and place the ceramic mug underneath the spout. You’ll then want to start a brew cycle on the largest setting your cup can accommodate. Once the brew is finished, discard the contents of the cup and run another cycle. Repeat until the water tank is empty.

Once the water reservoir is empty, let the whole machine rest for a good 30 minutes. This allows the vinegar to really soak in.

When the 30 minutes have passed, remove the reservoir and rinse it thoroughly. Last but not least, fill it with fresh water and run a few more cycles to banish any lingering vinegar taste.

Voila!
