Keurig Water Tank

Clogged water nozzles, mineral build-up, mouldy residue

There are many reasons why you might want to clean your Keurig tank deep. Fortunately, it’s easy! The following article will give you some valuable tips to know how to clean your Keurig tank.

There are two great ways you can clean your Keurig tank after it has been used. But, first, let’s look at the different methods.

Washing the tank by hand

If you don’t mind getting your hands dirty, washing your Keurig tank by hand is a simple (and messy) method for cleaning your water tank. Let’s get started!

Switch off the machine: 

Power off your Keurig machine. Don’t forget to unplug the power cord first! Then, remove any K-cup pods from the brewing chamber and throw them away.

Remove the water tank: 

First, remove the water tank. Since it may be heavy, you might find it easier to remove if you lay it on its side. Next, empty the old water of the Keurig tank. You can use a funnel to make this process very easy.

Wash the tank in warm soapy water: 

To ensure the inside of your tank stays clean, wash it thoroughly in soapy water. It can be done by hand or in the dishwasher (you’ll need to remove the pump first). Rinse thoroughly when finished. Wipe the base of the tank with a damp cloth to dry it.

Clean out any mineral deposits: 

Use vinegar to clean out any mineral deposits that might be stuck in your Keurig tank. Use 2-3 cups of vinegar on your water tank.

I recommend diluting the vinegar with warm water to make it easier to clean. You can also use a sponge or soft brush to remove the deposits. 

Rinse the tank thoroughly

When finished, thoroughly rinse your tank under warm water. You should rinse out any vinegar solution that might be left behind. Make sure you remove all the traces of soap and vinegar.

Dry the tank with a soft towel

Let the tank dry completely. It may take several hours. Once dry, reassemble your Keurig machine and brew a cup of tea as usual!

Descaling the machine

Descaling your Keurig machine is an option if you don’t like getting your hands dirty or if you want to make sure the inside of your tank is clean. To descale, follow these steps:

Clear the tank 

Throw the old water out of the Keurig tank. To do this, you can use a funnel to make the process very easy. Alternatively, you can pour all the water inside your Keurig tank into a bowl or sink.

Fill the tank with equal parts of vinegar and distilled water

You can dilute the vinegar with water if you’re not comfortable pouring it directly into the tank. Fill the tank with equal parts of white vinegar and water.

Make sure no chunks of vinegar or other complex substances remain in your tank! You may use a funnel as well.

Run some brew cycles with the hot water

When you finish filling the tank, switch on the Keurig machine to run a brew cycle. After the process is completed, run a few more cycles to ensure the build-up is all gone.

If you're not sure how long to leave your machine on, this step is an excellent way to test it out!.

Rinse from top to bottom with distilled water

After all these cycles, you’ll need to run a few brew cycles on the machine’s on-demand setting. Run several times on this setting until you get rid of any excess build-up. 

Spot clean any spots you may see with a soft cloth or rubbing alcohol. Repeat the brew cycles with only water this time.

Dry the tank with a towel

Last but not least, be sure to wipe out any excess vinegar solution in your Keurig tank with a clean towel. Once it’s dry, reassemble your machine and brew up a nice hot cup of tea!


So, in conclusion, you can use both methods to clean your Keurig tank. However, we recommend using the vinegar method (unless you’re not using the easy fill method). 

It's a much more thorough process that will ensure your Keurig tank will stay clean for much longer. 

One last thing: Whatever method you choose- make sure not to disturb your Keurig machine’s internal components (e.g. pump, hoses).

If you do not know how to clean the Keurig water tank properly, we recommend that you call in a service company instead.
