Why Regular Cleaning is Essential?

Maintaining the Taste of Your Coffee

The most immediate benefit of regular cleaning is the taste of your coffee. Over time, mineral deposits from water can build up in your Keurig Supreme, affecting the taste of your coffee. Regular cleaning ensures that every cup of coffee tastes fresh and delicious.

Extending the Life of Your Machine

Regular cleaning is not just about taste—it’s also about the longevity of your machine. Mineral build-up can cause blockages and other issues over time. By cleaning your Keurig Supreme regularly, you can prevent these issues and ensure that your machine lasts for years to come.

Preventing Bacteria and Mold

Did you know that a neglected coffee maker can be a breeding ground for bacteria and mold? Regular cleaning keeps your machine hygienic and safe to use.

Saving Money

Regular maintenance of your Keurig Supreme can save you money in the long run. By preventing issues and extending the life of your machine, you avoid the cost of repairs or replacement.

Materials Needed for Cleaning Your Keurig Supreme

Before you start the cleaning process, it’s important to gather all the necessary materials. Here’s what you’ll need:

  1. White Vinegar or Keurig Descaling Solution: These are used to dissolve and remove the mineral build-up inside your machine. You can use either of these, but the Keurig Descaling Solution is specially designed for this purpose.
  2. Fresh Water: You’ll need fresh water for the rinsing process after descaling.
  3. Large Mug: A large mug is needed to catch the water and descaling solution as it’s dispensed during the cleaning process.
  4. Soft Cloth: A soft cloth is useful for wiping down the exterior of your machine.
  5. Non-abrasive Sponge: If there are stubborn stains on the exterior, a non-abrasive sponge can be used to gently scrub them away.

With these materials at hand, you’re ready to start the cleaning process. Remember, regular cleaning is essential for maintaining the performance and longevity of your Keurig Supreme.

Step-by-Step Cleaning Process

Cleaning your Keurig Supreme is a straightforward process. Here’s a step-by-step guide:

  1. Preparation: Start by turning off and unplugging your Keurig Supreme. Remove any K-cups or pods from the machine.
  2. Descaling Solution: Fill the water reservoir with a 1:1 ratio of white vinegar or Keurig descaling solution and water. This solution will help to dissolve and remove the mineral build-up inside your machine.
  3. Descaling Process: Plug in and turn on your Keurig. Place a large mug on the drip tray. Start the descaling process by holding the 8oz and 12oz buttons at the same time. Repeat this process until the “ADD WATER” light illuminates.
  4. Rinsing: After the descaling process, empty the mug and rinse the water reservoir thoroughly. Fill the reservoir with fresh water and run the brewing cycle until the “ADD WATER” light illuminates again. Repeat this rinsing process at least twice to ensure all descaling solution is flushed out.
  5. Final Steps: Wipe down the exterior of your machine with a soft, damp cloth. Your Keurig Supreme is now clean and ready to brew the perfect cup of coffee!

Remember, regular cleaning is essential for maintaining the performance and longevity of your Keurig Supreme.

Cleaning the External Parts of Your Keurig Supreme

Cleaning the external parts of your Keurig Supreme is just as important as cleaning the inside. Here’s how to do it:

  1. Water Reservoir: Remove the water reservoir and lid. Clean these parts with warm, soapy water. Rinse thoroughly and allow them to dry before reassembling.
  2. Drip Tray: The drip tray can collect a lot of spills over time. Remove it and wash it in warm, soapy water. Dry it well before putting it back.
  3. K-Cup Holder: The K-cup holder can also be removed and cleaned. Be careful, though, as the needle inside is sharp.
  4. Machine Surface: Wipe the surface of the machine with a damp cloth. For stubborn stains, a little mild detergent can help.

Remember, a clean machine not only looks good but also ensures that your coffee tastes its best. Regular cleaning of both the internal and external parts of your Keurig Supreme will keep your machine running smoothly and your coffee tasting great.

Troubleshooting Common Issues with Your Keurig Supreme

Even with regular cleaning, you might encounter some issues with your Keurig Supreme. Here’s how to troubleshoot the most common problems:

  1. Machine Not Brewing: If your machine is not brewing, it could be due to a water line blockage. Try running a brew cycle without a K-cup to clear any blockages.
  2. Weak Coffee: If your coffee tastes weak, it might be due to a clogged needle. Clean the needle carefully using a paper clip or needle cleaning tool.
  3. Descale Light Stays On: If the descale light stays on even after descaling, unplug the machine for a few minutes, then plug it back in. This should reset the descale light.
  4. Machine Shuts Off Unexpectedly: If your machine shuts off unexpectedly, check the auto-off feature in the settings. Make sure it’s set to your desired time.

Remember, if you’re unable to resolve an issue, it’s best to contact Keurig customer service for further assistance. Regular cleaning and maintenance can prevent many common issues, ensuring your Keurig Supreme brews the perfect cup of coffee every time.

Professional Tips for Keeping Your Keurig Supreme Clean

Keeping your Keurig Supreme clean is not just about following the cleaning process. Here are some professional tips to help you maintain your machine:

  1. Regular Cleaning: Don’t wait for your machine to start acting up before you clean it. Make cleaning a regular part of your routine. A good rule of thumb is to descale your machine every 3-6 months, depending on your usage.
  2. Use Filtered Water: Using filtered water can reduce the amount of mineral deposits in your machine, which means less cleaning for you.
  3. Empty the Drip Tray Regularly: Don’t let water sit in the drip tray. Regularly emptying it can prevent mold and bacteria growth.
  4. Clean After Brewing Flavored Coffee: Flavored coffee can leave oils that build up over time. Rinse the brew basket after brewing flavored coffee to keep your machine clean.
  5. Store Properly: If you’re not going to use your Keurig Supreme for a while, empty the water reservoir and leave it open to air dry. This prevents mold and bacteria from growing.

Remember, a clean Keurig Supreme means a better tasting coffee. So, keep your machine clean and enjoy your perfect cup of coffee every time!


In conclusion, cleaning your Keurig Supreme is an essential part of maintaining its performance and longevity. By following the steps outlined in this guide, you can ensure that your machine continues to brew the perfect cup of coffee every time.

Remember, regular cleaning not only improves the taste of your coffee but also extends the life of your machine. So, make cleaning your Keurig Supreme a regular part of your routine. Happy brewing!
