Stop! Don't Brew Another Cup Until You Finally Clean Your Keurig

Making your own coffee at home is an easy way to save money, which is especially important with grocery prices on the rise. But if you use a Keurig, we have one important question for you: When was the last time you actually cleaned it?

This is a no-judgement zone. But a coffee maker that's not getting cleaned is a harbor for bacteria, grime and mold. Let it go on long enough, and that buildup can actually put your health at risk. 

"Keurig sickness" is a real phenomenon -- confirmed by Snopes. The warm, moist environment inside is a veritable breeding ground for stuff you really don't want to be drinking, and ingesting mold can have serious health implications.

The good news? It's completely preventable. 

Regular descaling and washing of removable parts will extend your machine's life and prevent your morning brew from tasting like swamp water and growing dangerous mold.

Here's a guide to cleaning and descaling your dirty Keurig today.

Before cleaning your Keurig

Before you start cleaning your Keurig, make sure there isn't a used pod still in the machine's pod holder. Leaving your K-Cups for days on end before taking them out can promote mold growth, and where do you think that mold could eventually end up? That's right, your favorite coffee mug. Take your K-Cups out after your brew has cooled a bit. 

Make sure you also unplug your Keurig before cleaning. This will make it easier to spin it around and move it if necessary while you're cleaning it.

Wash down the outside of your machine

We're not talking about using a water hose, but give your Keurig a nice cleaning on its exterior surfaces to remove any dried coffee residue. Keurig itself suggests wiping down your machine every day. 

Clean the drip tray

Spilled coffee is likely to build up in the drip tray, so make sure you're emptying and cleaning it regularly. Otherwise, expect mold and smells to develop after weeks of neglect. Washing the drip tray is quick and easy -- dish soap and warm water will do the trick. 

Clean the reservoir

Although its primary purpose is just to hold water, don't skip on giving the water reservoir and lid some love. You can hand wash it with warm water and dish soap or throw it in your dishwasher. Before you clean these, make sure you take out the water filter at the bottom of the reservoir first; otherwise, you just made a new problem for yourself.

Clean the K-Cup holder 

This part of your Keurig sees most of the action and in turn, can be one of the grosser parts to clean. While it's best if you clean every part of your machine, if you choose to just do one of these steps, it should be this one, by a lot.  

Check the user manual that came with your machine or online to see how to properly remove the holder and so you can clean underneath it. You can run the holder under hot water to wash away any coffee grounds, residue or oils, but wiping it down a bit will be helpful as well. Also, don't forget there's a sharp needle in this area for puncturing K-Cups, so take care around it.

Descale your machine with vinegar or a descaling solution

This one you probably expected to see on this list at some point. But if you didn't know, descaling your machine is a necessary task to ensure your machine works properly and continues to do so in the long run. 

Given the sheer number of different models, activating the descaling mode on your specific coffee machine may be a little different, but Keurig's descaling support page should help you find the right combination of buttons to press. 

In general, descaling involves filling your Keurig's water reservoir with a mixture of vinegar and hot water (or Keurig's pre-made solution) and running all of the solution through the machine without a pod until you need to add more water. Make sure you have a container large enough to catch the vinegar-and-water solution as it flows out. Let the Keurig sit for a few minutes and then fill the reservoir with water and repeat the brewing process. You'd probably benefit from repeating this a few times to avoid any potential vinegar aftertaste. 

Luckily, descaling your machine isn't required weekly. Keurig encourages you to descale every few months, though.
