How to Clean a Keurig: A Simple Step-by-Step Guide
Keep your single-serve brewer running at its best with these easy cleaning steps.
A dirty Keurig brews slower, produces weaker coffee, and can even develop a sour or off taste over time. Mineral deposits from tap water build up inside the machine, and old coffee oils linger in the pod holder and drip tray. The good news is that cleaning a Keurig takes very little time and only a few basic supplies. Follow the steps below and your brewer will keep performing like it should.
What You Need Before You Start
You do not need any special cleaning products. White distilled vinegar or a Keurig-brand descaling solution will handle the internal buildup. For the external parts, mild dish soap and warm water are all you need. Have a clean cloth or paper towels on hand, and make sure you have access to your sink. That is really all there is to it.
Daily Cleaning: Quick Rinse After Every Use
After your last cup of the day, remove the used K-Cup and give the pod holder a quick rinse under the tap. Wipe down the outside of the machine with a damp cloth to catch any drips or splashes. Empty the drip tray and rinse it with soapy water. This takes about two minutes and prevents residue from building up in the first place. The less grime that accumulates day to day, the easier your weekly cleaning will be.
Weekly Cleaning: Wash the Removable Parts
Once a week, take off the water reservoir, lid, drip tray, and pod holder assembly. Wash each piece with warm soapy water, rinse well, and let them air dry before putting them back. Do not put plastic parts in the dishwasher unless the manual for your specific model says they are dishwasher safe. Many Keurig parts are not rated for the dishwasher heat and can warp over time. Reassemble everything once the parts are fully dry.
Monthly Cleaning: Descaling to Remove Mineral Buildup
Descaling is the most important maintenance step and should be done roughly once a month if you use your Keurig daily. Empty the water reservoir and remove any water filter. Add your descaling solution or plain white vinegar, then fill the rest of the reservoir with water according to the solution directions. Run several brew cycles without a pod until the reservoir is empty, letting the liquid flush through the internal tubes and heating element. Those cycles dissolve the limescale that makes your machine work harder and your coffee taste flat.
After Descaling: The Rinse Cycles
Once the descaling cycles are done, fill the reservoir with fresh clean water and run at least two full reservoirs worth of plain water through the machine. This flushes out any remaining vinegar or descaling solution so it does not end up in your next cup of coffee. Skip the rinse cycles and your coffee may have a sharp acidic taste for days. This part is easy to rush, so take your time and do both rinse rounds completely.
Cleaning the Needle (When Your Brewer Clogs)
If your Keurig starts brewing very slowly or stops mid-cycle, coffee grounds may have clogged the needle that pierces the K-Cup. Power off and unplug the machine first. Open the pod holder and look for the small needle inside. Use a straightened paper clip to gently clear any grinds from the hole. Keurig also sells a needle-cleaning tool that fits right into the pod holder and does the job without requiring you to locate the needle by touch. After clearing the clog, run a water-only cycle to flush out anything loosened.
How Often Should You Descale?
A general rule of thumb is to descale every one to three months depending on how hard your local water is and how often you brew. Hard water areas with high mineral content need more frequent descaling. If your machine starts prompting you with a descale light, do not ignore it. Running a machine with heavy scale buildup puts extra stress on the pump and heating element, which shortens the life of the brewer. A quick monthly descale is far cheaper than replacing the unit.
Frequently asked questions
Can I use white vinegar to descale my Keurig?
Yes. Fill the reservoir with equal parts white distilled vinegar and water, run brew cycles until it is empty, then follow up with two full reservoirs of plain water to rinse. White vinegar works well and costs very little.
How do I know when my Keurig needs descaling?
Many newer models show a descale indicator light. Even if yours does not, a good rule is to descale every one to three months. Signs that it is overdue include slower brewing, a smaller cup output, or coffee that tastes unusually weak or off.
Are Keurig water reservoirs dishwasher safe?
It depends on the model. Some reservoirs are labeled dishwasher safe on the top rack, while others are hand-wash only. Check your model's manual to be sure. When in doubt, hand washing with warm soapy water is always safe.
Why does my coffee taste like vinegar after descaling?
You did not run enough rinse cycles. After descaling, flush the machine with at least two full reservoirs of fresh water. If the taste persists, run one more rinse cycle.
How do I clean the Keurig needle?
Power off and unplug the brewer. Open the pod holder and use a straightened paper clip or the Keurig needle-cleaning tool to clear any coffee grounds from the puncture hole. Then run a water-only brew cycle to flush out loosened debris.
