The horrible symptoms of peeling on your Keurig are unconscious: slower pours, settings that no longer work, stinking buildup and half a cup of coffee when you really needed the full cup.
Scaling occurs when hard deposits in water – water with a lot of minerals in it – attached to the inside of Keurig, gradually clog up their pipes (the same can also happen with your plumbing). More advanced Keurigs will often tell when it's time to descale, but it is generally a good idea to do it every six months if you use regular tap water. How to descale a Keurig when the time comes.
Note: This is about descaling specifically. If you want to give a dirty Keurig a thorough cleaning, check out our guide on how to do it as well.
Step 1: Prepare your Keurig
Empty Keurig, then clean a nearby sink to create plenty of space. Keep anything in the container in the drain and make sure that there are no K-cups left in the brewer. Find a large mug that will be used for drainage, and make sure no one will need their coffee fix for the next few hours.
Step 2: Prepare your descaler
Now you need an acid descaler to run through your brewer so that it can break apart the calcium insert. Keurig Descaling Solution : Keurig sells its own descaling solution that you can buy for about $ 7 to $ 15, which lasts for a single use. It is a simple option that does not require much effort, and all accounts are stripped off. But if you read the reviews on both Keurig's own product page (where it only gets three stars) and on Amazon, you will find that the solution tends to have a citrus odor that can be very difficult to get rid of, and can even get white vinegar : White vinegar is very cheap, easily accessible and works well on the scale. You need at least several cups for a good cleaning, which means that you may have to go out and buy more specifically for this project. It is also vinegar, which means that your kitchen or interruption can cause vinegar to smell for a while.
If you use the Keurig solution, you want to empty the entire bottle into the container and then fill the rest with clean water. For white vinegar you want your container filled with half vinegar and half water – possibly even more vinegar than water for a really hard descaling job.
Step 3: Run your descaler by Keurig
] Set your Keurig for a regular, full cup of coffee – you can go bigger if you have thermos nearby, but a mug usually works best. (And again, make sure there is no K-cup inside.) Run the descaling solution and wait for the cup to fill.
If your Keurig has a large scale problem, you may not be able to fill up a whole cup even in the right settings. It's okay, the solution takes some time to work. Continue filling cup after cup and pouring them into the drain. If you used the white vinegar solution, the room is really to begin to smell like vinegar, but hang in and continue until the container is empty.
At the end, the water should pour more smoothly and fill up copper with a little more ease. If you don't notice any improvement at all, you might want to fill the container with more solution and repeat the whole process just to make sure.
Step 4: Flush Keurig with fresh water
Leave Keurig to sit (still switched on) for a while, about 30 minutes. This gives the acid time to break down the remaining scale within the brewery. Carefully clean the container and wipe the inside to remove any traces of vinegar / solution. When done, fill the container with clean, fresh water. It is time to flush out the entire descaling solution from the system.
Replace Keurig for a whole cup and start running cup after cup of water through the brewery and dump each. When the water tank is empty, it is filled up again and continues to do the same. It will take at least two full water reservoirs to flush out your Keurig, so prepare to get rid of a lot of water.
At this point, you might want to do a taste test to see if you can taste any of the descaler remaining in the water. Don't be afraid to flush it out a couple of times, as the flushing can never be too thorough.
How to prevent scale buildup in your Keurig
Generally, molds are easier from tap water. That is why Keurig suggests that you use filtered or bottled water to fill up the brewery and help keep the shell problems to a minimum. Bottled water is an expensive option, but you may want to consider buying a simple water filter to use only for your Keurig, if the scale has been an ongoing issue for you.
