You should free your coffee maker from scales at least every 3 months. Scaling is from the buildup of calcium deposits in your coffee maker. They are non-toxic but will hinder your coffee maker’s performance over time. There are different methods for the various models of the Keurig Brewers. So, make sure that you are using the correct one for your model.
Any Standard Keurig Brewer
The most used method of cleaning your brewer is to have the following supplies on hand; descaling solution, a mug (don’t use a paper cup) and access to a sink. Power off the brewer and empty the water reservoir. If you have a water filter, remove it from the brewer and set aside. Make sure that the auto off feature is disabled. For brewers with a removable reservoir, fill it with the water solution. Then fill the empty bottle with water and add that to the reservoir.
The next step is to power up the system and place an empty mug on the drip tray. Choose an 8 oz brew size and then press the brew button. If you don’t have an 8 oz brew size then choose the largest one available. Keep repeating the process until the brewer asks for more water. Let the brewer sit for 30 minutes while it is still plugged into the socket. Remove the reservoir, empty it and then rinse it thoroughly. Repeat the process 12 times filling the reservoir as needed.
K 15 Brewer
The directions are the same as the other brewers except for a few steps. First, only pour 1/3 of the solution into the reservoir. Add fresh water to the 10 oz. fill level. Press brew to perform a cleansing brew. Repeat the process one more time with the solution and fresh water. When it starts to dispense, press the power button off. Perform the cleansing brew at least 3 times using fresh water and 1/3 of the solution each time. The brewer should be scale free and ready for a fresh pot of coffee.
K Cup Brewer
To descale the brewer, the same ingredients are needed plus you also need a timer. The process should take about 15 minutes plus a 30 minute waiting time. You need to do the cleansing cycle at least 12 times while emptying out the water in the mug each time. You may need to refill the reservoir with fresh water. Reinstall the filtration system and you are ready to make your cup of fresh coffee.
During the cleansing process, you might see foam being dispensed from the brewer. This is normal. It is a chemical process of the solution reacting to the scale inside of the brewer. If your brewer is heavily scaled, it may not fill properly. You may see little to no output from the dispenser. If this happens, unplug the brewer from the outlet. If there is any solution left in the reservoir, discard the solution, rinse thoroughly and then refill the reservoir with fresh water. Plug the brewer back in, power on the machine and repeat the fresh water rinse cycle. If it still doesn’t dispense, unplug the brewer and let the machine sit for at least 30 minutes. Continue with the rinse.
Keurig recommends doing this process every 3-6 months. If your water is hard, you may have to do it more often. Instead of the cleaning solution, you can also use a half and half solution of vinegar and water.
To reduce buildup in your brewing system, you should use bottled or spring water. If your brewer isn’t dispensing properly, you can clean the exit and entrance needles. The instructions are in your manual or can be found at Keuring in their video section. To dislodge any debris in the system, you can try and blow it away with a straw.
Keeping your system in top condition will mean that you will have a fresh cup of coffee whenever you would like.
