Before you begin, you will need a large ceramic mug, fresh water,  

Keurig

™

 Descaling Solution and access to a sink. Do not use a paper cup.

Empty the water from the Water Reservoir. If there is a Keurig

™

 Water Filter, remove 

and set aside. Disable Auto Off features per the Owner’s Manual for your brewer,  

if necessary.

STEP 1: FIRST DESCALING SOLUTION RINSE

•  Press the Power Button or Switch to power the brewer off.
•  Pour the entire bottle of Keurig

™

 Descaling Solution into the  Water Reservoir. 

Then fill the empty bottle with fresh water and pour into the Water Reservoir. 

Then turn the brewer back on.

•  Place a large mug on the Drip Tray Plate and run a cleansing brew using the 

largest brew size. Do not add a K-Cup

®

 pack.

 Pour the contents of the mug 

into the sink.

STEP 2: SECOND DESCALING SOLUTION RINSE

•  Repeat the brew process without a K-Cup

®

 pack, until “Add Water” is indicated. 

Let brewer stand for at least 30 minutes while still on.

•  After 30 minutes, discard any residual solution and rinse the Water  

Reservoir thoroughly.

STEP 3: FRESH WATER RINSE

•  Ensure the Water Reservoir is filled with fresh water. 
•  Place a large mug on the Drip Tray Plate and run a cleansing brew using the 

largest brew size. Do not add a K-Cup

®

 pack.

 Pour the contents  

of the mug into the sink.

•  Repeat brew process until you have completed at least 12 brews using the 

largest brew size. You may need to refill the Water Reservoir at least one time 

during this process.
NOTE: The cleaning action of the Keurig

™

 Descaling Solution may result in a 

foam dispensed from the brewer. This is natural, as the solution is reacting 

with the scale inside. For a brewer that is heavily scaled, the brewer may not 

fill properly after the descaler is added. If this occurs, you may see only  

a small or no output dispensed followed by the sound of air blowing out.  

If this occurs:

•  Turn off and unplug the brewer.
•  If there is Keurig

™

 Descaling Solution in the Water Reservoir, discard the 

contents, rinse the Water Reservoir thoroughly and refill with water.

•  Plug the brewer back in, power on, and repeat the Step 3 Fresh Water Rinse 

cycle. The brewer should begin to function normally as the solution is rinsed 

out and the scale is removed. If problem persists, allow the brewer to sit 

unplugged for at least 30 minutes before continuing with the rinse.
