Keurig coffee makers have become a staple in many kitchens and offices, providing an easy and convenient way to brew a cup of coffee. However, frequent use of this machine can lead to a buildup of coffee grinds, oil, and even mould. Proper cleaning is essential to maintain the machine’s performance and longevity. Here is a step-by-step guide to help you effectively clean your Keurig coffee maker.

Why Regular Cleaning of a Keurig Coffee Maker Is Essential

Your Keurig machine can accumulate mineral deposits over time, especially if you use hard water. Minerals can clog the machine’s inner components, impeding its functionality and potentially ruining the taste of your coffee. Additionally, a buildup of coffee grounds can create a breeding ground for bacteria and mould, posing health risks. Therefore, it’s advisable to clean your Keurig every 3 to 6 months for optimal performance and taste.

Supplies You’ll Need to Clean a Keurig Coffee Maker

Before you start to clean your coffee maker, gather all the necessary supplies:

  1. White vinegar or Keurig’s descaling solution
  2. A soft, non-abrasive cloth
  3. Mild, non-bleach dish soap
  4. A sponge
  5. An old toothbrush (optional)
  6. Freshwater

Step 1: Unplug and Disassemble 

First, always ensure that your machine is unplugged before you begin. Working with electrical appliances requires the utmost priority on safety. Once the machine is unplugged, remove the reservoir, drip tray, and K-cup holder. These are all dishwasher safe, but you can also clean them by hand with warm soapy water.

Step 2: Clean Removable Parts

Use your non-abrasive cloth and mild soap to clean each part thoroughly. Pay extra attention to the K-cup holder, as coffee grounds can get stuck in this piece. An old toothbrush can be handy for scrubbing these stubborn areas. Once cleaned, rinse thoroughly and let them dry before reassembling.

Step 3: Wipe Down the Machine

Wipe down the exterior of the machine using a damp cloth. Remember not to use abrasive cleaners or scouring pads as they could damage the surface. Be sure to clean the area around the coffee pod slot as well, where coffee residue can build up.

Step 4: Descale the Machine

Descaling is a crucial step in cleaning a Keurig, as it removes mineral deposits that can hinder the machine’s performance. To descale, fill the reservoir with a mixture of half white vinegar and half water, or use Keurig’s descaling solution as directed. Run the machine without a K-cup until the reservoir is empty, discarding the water/vinegar mixture after each brew.¬†

Step 5: Rinse Thoroughly 

After descaling, it’s essential to rinse the machine thoroughly to remove any remaining vinegar or descaling solution. Fill the reservoir with fresh water and run the brewing cycle until the reservoir is empty. Repeat this step until the smell of vinegar or the descaling solution is completely gone.

Maintenance Tips

Regular cleaning ensures your Keurig stays in top condition, but there are additional steps you can take to maintain your machine:

– Use filtered or bottled water instead of tap water to reduce mineral deposits.

– After each use, remove the used K-cup promptly. This prevents the needle from clogging and reduces the risk of mould and bacteria.

– Keep the exterior of your machine clean by wiping it down weekly.


In conclusion, dedicating some time to regularly cleaning your Keurig coffee maker is essential for maintaining its optimal performance and extending its longevity. Although it may feel like a mundane task, the results are truly rewarding when you savour the delightful flavour of a freshly brewed cup of coffee from a pristine machine. Embracing this cleaning routine guarantees consistently excellent taste and a prolonged lifespan for your beloved Keurig coffee maker.
