The task can seem quite daunting because of the smaller parts involved, but we’re here to help get you through it.
In this article we will cover cleaning and descaling in depth. This will help you keep your Keurig operating correctly and keep it free of germs and mineral build up.
There are 3 major steps when cleaning a Keurig including removable parts, internal parts, and descaling.
You probably already have the equipment needed, so let’s get started!
The following video is an excellent tutorial by Melissa Maker.
You Will Need:
- White vinegar (Optional: Keurig Decaling Solution)
- Kitchen towel or microfiber cloth
- Paper Towels
- Keurig 2.0 maintenance accessory (If you have a 2.0 machine)
- Tooth brush
- Dish washing liquid
- All-purpose cleaner
- Paper clip
- Drinking straw

Cleaning Removable Parts
- Unplug the machine. Never clean or take apart your Keurig while it’s plugged in. Make sure you are working in a well-lit room that is free of clutter. Safety first!
- Remove the lid and water reservoir. You will notice instructions under lid as to how to clean the lid with damp cloth and that the reservoir is dishwasher safe. When removing the water reservoir make sure that you don’t misplace the O-ring otherwise your Keurig will leak the next time you try to use it.
- Remove k-cup holder and funnel. Be careful of the sharp needle(s) that puncture the Keurig cups.
- Remove drip tray and drip tray cover if applicable.
Most of these items are dishwasher safe, but we recommend adding the items (not the entire machine) to sink fully of warm soapy water and let them soak for 10-15 minutes, rinse and towel dry.
Dishwashers can be harsh on plastic items. We get a lot of complaints about water reservoirs plastic turning cloudy or warping the reservoir. The culprit always seems to be dishwashers (possibly the detergent) and hot water. You should never scrub the reservoir, just a gentle wipe with a soft cloth will do. Acrylic scratches very easily.

Step 1 - Clean K-Cup Area With Toothbrush
Use a toothbrush to remove coffee grounds in and around the K-Cup holder space.
Step 2 - Clean K-Cup Area With Paper Clip
Use a paper clip to gently push inside the holes that pierce the K-Cup. These holes easily get clogged with coffee and mineral build up. You may have to wiggle the paper clip inside the holes. If a paper clip does not fit, you will need to find something smaller.
Note: The water line may get clogged at this point during the descaling process, so it’s important to be aware of it. If that happens, simply wiggle the paper clip inside, put the machine back together, and finish the descaling process.
Don’t worry about breaking anything inside the holes, they are simply the water lines with no working parts inside.
You may also try turning the Keurig machine upside down and giving it a “gentle tap” on the bottom to help dislodge anything that may be stuck inside.
Step 3 - Clean Water Line With A Straw
Locate the water line spout and connect the straw to it. You may have to use your fingers to help make a seal.
Blow air through the straw to help try to dislodge any debris inside the water line. You will have to blow extremely hard. If you don’t have the ability to do this don’t worry about this step, it’s not that important.
Step 4 - Clean With All-Purpose Cleaner
Use microfiber cloth and all-purpose cleaner to clean the outside of the machine. We recommend spraying cleaner on to the cloth instead of directly on the Keurig. This will help prevent cleaner from getting in unwanted areas.
Alternatively you can use soapy water to clean and rinse using a damp cloth. Some areas may need a bit of elbow grease to get clean. Take your time and work on getting things as clean as possible.
Step 5 - Clean Water Reservoir & Mesh
Remove the water reservoir and empty it. Remove the water filter if your Keurig has one. Turn on your tap water full stream and allow it to run over the mesh filter inside. This will help dislodge any debris.
White scaling can appear, especially around the reservoir area. This can be cleaned using white vinegar. We recommend using a paper towel that is damp with vinegar to wipe the area.
You may have to soak the area and let the vinegar penetrate for a minute before wiping with a damp cloth and water. Again, a little elbow grease may be required until it all disappears.
Descaling A Keurig
Brewer descaling is a process which removes mineral buildup, typically limescale. You’ve probably seen it before, a hard white substance that usually builds up in coffee makers.
This can happen quite rapidly if your tap water contains a high level of minerals and is allowed to evaporate.
Tap water that has a large amount of these minerals is often referred to as hard water. Over time this buildup can clog lines or it can break off in small pieces. This is often the reason why the water reservoir and feeding line fail to operate correctly in a Keurig brewer.
Note: You don’t have to clean your Keurig before descaling. However, it is probably a good idea to help the descaling process and remove as much buildup as possible through the whole machine.
Keurig Descaling Instructions
- Reassemble your Keurig as if you were ready to brew a fresh cup of coffee. Ensure that all pieces are seated properly. Don’t forget that water reservoir O-ring!
- Fill the water reservoir with white vinegar, about half way to make vinegar water.
- Run a brewing cycle to make “hot vinegar”
- Dispose of the hot vinegar when the cycle completes.
- Continue brewing and discarding the vinegar until the reservoir is empty.
- Refill the reservoir with water.
- Brew hot water and discard until the reservoir is empty. This is to remove all of the vinegar from the system.
- Now you’re ready to brew a fresh cup of coffee in your clean Keurig!
Keurig 2.0 Owners
Unfortunately, you will need the maintenance accessory to preform a cleansing brew. If you didn't receive one with your Keurig, you will have to purchase one separately or contact Keurig to see if they will ship one to you.
Some people have a reusable K-Cup that is dedicated for cleaning.
Vinegar vs Descaling Solution
Earlier we mentioned about descaling solution which comes in liquid form. The main ingredient is usually citric acid whereas white vinegar is about 3% acetic acid and 97% water.
There are a variety of descaling solutions available on the market to clean coffee machines, of course Keurig Descaling Solution is recommended. Other brands can quite harsh compared to vinegar and ruin parts inside your coffee maker.
If you plan on using a descaling solution, see box for directions. Make sure that your descaling solution is safe to use in Keurig machines. The process should be the same but instead of using vinegar you would replace with descaling solution.
Keurig Descaling Solution
While we recommend using plain white vinegar, you may want to try using descaling solution offered by Keurig.
There are a few things you need to know about it.
- The solution is citric acid based and it may leave a chemical taste in your Keurig even after multiple cleansing brews.
- It may not be as effective as vinegar.
- It’s expensive compared to vinegar.
But if the vinegar treatment isn’t working for you, you may want to give this a shot. Who knows, it just might fix your clogged Keurig.
Tips To Keep Your Keurig Clean
Tip #1 – Don’t Leave Water Sitting
Don’t leave water sitting in water reservoir for more than a week. Mineral deposits will build up as the water evaporates and you will need to spend more time cleaning and descaling when you decide to use it again.
Depending on a variety of factors, you could also start to grow mold in your coffee maker which could make you sick. We wrote about that in our article Mold in Coffee Maker.
Tip #2 – Use Filtered Tap Water
Keurig recommends using distilled water to make coffee and prevent excess mineral buildup. However, there is a debate that drinking distilled water may not be good for your health.
The claim is that because it’s devoid of minerals, it acts like a sponge taking minerals out of your body. The Huffington Post goes in to details about it at the Hidden Dangers of Drinking Water.
We recommend that you use a simple water filtration pitcher, if your Keurig model doesn’t have one, to help remove unwanted chemicals and tastes from your tap water. This will help give you better tasting coffee.
Tip #3 – Clean After Sticky Brews
If you make sticky drinks like hot chocolate, caramel apple cider, or sugar cookie coffee be sure to run a cycle of hot water immediately afterwards. This is also known as a cleansing brew, brewing hot water with no K-cup in the K-cup holder to clean the unit.
The problem with sticky drinks is that sugar crystallizes and clogs the system much like minerals do. Not to mention, you might invite unwanted pests if your Keurig is a sweet sugary mess.
The cleanup is compounded if you are using reusable K-Cups since you will also be needing to clean that unit as well.
That’s all there is to cleaning your Keurig! After you have cleaned and descaled for the first time, the second time will feel easier and go much smoother.
