How to Clean Your Keurig Coffee Machine: A Step-by-Step Guide
Enjoying a fresh cup of coffee from your Keurig is the perfect start to any day. But did you know your coffee maker needs regular cleaning to keep it working smoothly and ensure every brew tastes delicious? If your Keurig has started to lag, taste bitter, or look a bit dirty, it’s time for a deep clean. This guide will show you exactly how to clean and descale your Keurig—quickly, easily, and safely.
Why You Should Clean Your Keurig Regularly
Coffee machines are breeding grounds for germs, mold, and mineral scale build-up. Over time, leftover grounds, oils, and hard water deposits accumulate inside your Keurig. This can cause:
- Slower brewing times
- Off flavors or bitter coffee
- Shortened machine lifespan
- Possible health risks from mold or bacteria
By following a simple cleaning schedule, you’ll extend the life of your brewer and enjoy better-tasting coffee.
What You’ll Need
Before you start, gather these supplies:
– White distilled vinegar or Keurig descaling solution
– Mild dish soap
– Clean, soft cloth or non-abrasive sponge
– Large ceramic mug (no paper or styrofoam)
– Fresh water
– Paperclip (optional, for unclogging needle)
– Dry towel
Step 1: Unplug and Disassemble the Keurig
- Turn off and unplug your Keurig.
- Remove detachable parts: Take out the water reservoir, drip tray, pod holder, and (if possible) the funnel.
- Empty the water reservoir and discard any used pods.
Taking the machine apart allows for a more thorough cleaning and prevents electrical mishaps.
Step 2: Clean Removable Parts
Wash the following parts with warm, soapy water:
– Water reservoir and lid
– Drip tray and drip plate
– Pod holder
– Funnel (if removable)
Tips:
– Use a soft sponge—avoid scratchy pads.
– Let parts air dry or dry with a clean towel.
– Do not put the water reservoir or lid in the dishwasher unless the manufacturer allows it.
Step 3: Wipe the Exterior
Wipe down the outside of your Keurig with a damp cloth. Pay attention to:
– The machine’s body
– The area around the pod holder
– The base and catch tray
Pro tip: For stuck coffee grounds, use a damp toothbrush or a small brush.
Step 4: Clear the K-Cup Needle
Ground coffee can clog the entrance and exit needles, causing clogs or short cups.
- Open the brew head.
- Carefully insert a straightened paperclip into the needle holes to loosen any clogs.
- Gently tap out loosened debris over the sink.
- Wipe the pod holder area with a damp cloth.
Always handle the needle with care to avoid injury.
Step 5: Descale the Internal Water System
Mineral deposits from hard water can build up inside your Keurig. Descaling removes these deposits, improving performance and taste.
How Often Should You Descale?
- Every 3 months if you use your Keurig daily.
- Every 1-2 months if you have hard water.
How to Descale:
Option 1: Using Vinegar
1. Fill the water reservoir halfway with white vinegar and the rest with water.
2. Place a large mug on the drip tray.
3. Run brew cycles without a K-Cup until the reservoir is empty. Pour out each mugful.
4. Let the machine sit for at least 30 minutes to allow the vinegar to break down scale.
Option 2: Using Keurig Descaling Solution
– Follow the instructions on the packaging for best results.
Step 6: Rinse and Flush
After descaling:
1. Rinse the reservoir thoroughly with fresh water.
2. Fill the reservoir with clean water (no vinegar or solution).
3. Run multiple brew cycles with just water (no K-Cup) until the reservoir is empty.
4. This removes vinegar or cleaning solution taste.
Tip: If you notice a lingering vinegar smell, repeat this rinse cycle.
Step 7: Reassemble and Brew
- Once all parts are fully dry, reassemble your Keurig.
- Plug in and power on your machine.
- Test by brewing a cup of hot water (no pod).
If the water tastes fresh, you’re ready to brew coffee again!
Benefits of Regular Cleaning
- Better-tasting, fresher coffee
- Faster brewing with less clogging
- Fewer germs, mold, and bacteria
- Longer life for your machine
- Consistent cup sizes and performance
Challenges and Troubleshooting
Even with regular cleaning, you might encounter occasional problems. Here’s how to handle common issues:
- Machine Won’t Brew: Check for needle clogs or ensure the reservoir is seated properly.
- Strange Noises: Mineral scale may still be present—repeat the descaling process.
- Short Cups: Unclog the needles and ensure the reservoir is filled.
- Plastic or Vinegar Taste: Run additional water-only cycles to flush out residues.
Practical Tips and Best Practices
- Use filtered water: This slows down scale buildup.
- Empty the reservoir nightly: This reduces the risk of mold.
- Leave the lid of the water tank open when not in use: Helps it dry completely.
- Wipe spills immediately: Prevents stains and bacteria.
- Set a cleaning reminder: Calendar notifications help you remember.

Frequently Asked Questions (FAQs)
1. How often should I clean my Keurig?
Ideally, you should wipe down and wash removable parts weekly, clean the needles monthly, and descale the machine every 2-3 months. Adjust the schedule if you have hard water or heavy use.
2. Can I use any type of vinegar for descaling?
It’s best to use white distilled vinegar. Other types (like apple cider or wine vinegar) can leave odors or flavors. Commercial Keurig descaling solutions are also effective and specially formulated.
3. Is it safe to put Keurig parts in the dishwasher?
Some parts, such as the drip tray or reservoir lid, may be dishwasher safe—always check your machine’s manual first. If in doubt, wash everything by hand.
4. My coffee tastes funny after cleaning. What should I do?
This usually means there’s leftover cleaning solution or vinegar. Run several water-only brew cycles to flush the system until the taste disappears.
5. How can I prevent clogs in my Keurig?
Routinely clean the needle and use filtered water when possible. Avoid leaving used K-Cups in the holder, since leftover grounds can dry out and clog the mechanism.

A clean Keurig gives you better-tasting coffee and a longer-lasting machine. By sticking to a regular cleaning schedule—washing parts, wiping the exterior, descaling, and checking for clogs—you’ll enjoy every cup with confidence.
