How to Clean a Keurig Coffee Maker

Step 2

After cleaning and drying all removable parts it is time to reassemble your Keurig coffee maker.

To clean the inside system of the Keurig coffee maker you can use Keurig descaling solution (pictured below) or you can use white vinegar. In this case we are going to use Keurig descaling solution.

Keurig descaler solution

Per the instructions in the bottle of Keurig descaling solution, we pour the full bottle into the water reservoir of your coffee machine.

We add the same amount of water so we can use the same bottle of keurig descaling to solution, but this time empty. We fill the empty keurig descaling solution bottle woth water, like in the picture below.

You should continue the cleaning process until the “Add water” light (Pictured below) turns on.

In this case it took 2 brews for “Add water” light to turn on (pictured below). This means the brewing process is over. You should let it sit for 30 minutes so that the hot descaling solution still in the system does its job of descale.

Step 5

Even though there is still descaling solution left in the water reservoir(pictured below) you should not run it throught the system. Just remove the water reservoir and discard the descaling solution that is left. Clean the water reservoir with soap and water to remove any descaling solution remains.

Now it is recommended to brew 12 big cups of fresh water through the system to remove any descaling solution left.

Continue adding fresh water to complete cleaning of Keurig coffee maker

In the picture below you can see there is still some descaling solution after 4 cups have been brewed. That is why it is required to complete 12 cups so that the descaling solution is completely removed form the Keuring system.

Tips for Regular Keurig Coffee Maker Maintenance

If you have hard water, or your machine requires cleanings more often than it should, consider using filtered water in the reservoir instead of water straight from the tap.

If you’re going on vacation or not planning on using your single-serve coffee maker for an extended period, empty the reservoir and turn off the machine.

Cleaning a glass coffee pot? Stick to completely all-natural cleansers, such as vinegar and a few tablespoons of salt. The salt will work like a scrub against any burnt-on coffee stains and spots on the interior.

FAQ

How often should I clean my Keurig?

If you use your Keurig coffee maker every day it is recommended to clean or descale it at least once a month. If you’re not using it every day you should at least descale it every 3 months.

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

In short YES. If the water where you live is hard, mineral buildup will occur faster, so you have to descale more often. You can use filtered water instead to avoid descaling more often.

If you don’t want to use fitlered water you should descale your Keurig coffee maker every week to avoid mineral buildup.

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