I really enjoy my morning cup of coffee, and one of my favorite ways to make it is with my Keurig coffee maker. However, over time, I noticed that the water reservoir can become dirty or develop a build-up that affects the taste of my coffee. That’s why I decided to learn how to clean my Keurig coffee maker water reservoir properly, to ensure I always get a fresh and flavorful brew. In this article, I will share the step-by-step process of cleaning the Keurig water reservoir, so you can enjoy a delicious cup of coffee every morning.

Gather the Necessary Supplies

The first step to cleaning the Keurig coffee maker water reservoir is to gather all the necessary supplies. Here’s what you will need:

Vinegar or Descaling Solution

Vinegar is a common household item that can be used for cleaning various surfaces. It works well for descaling and removing mineral deposits inside the water reservoir. If you prefer to use a commercial descaling solution, you can find them at most stores that sell Keurig products.


You will need clean water to rinse the reservoir after the cleaning process. Make sure you have enough water to fill the reservoir at least twice.

A Cleaning Cloth or Sponge

To wipe down the exterior of the coffee maker and remove any dirt or grime, you will need a cleaning cloth or sponge. Make sure it is clean and free from any chemicals or residues.

A Toothbrush or Cleaning Brush

A toothbrush or cleaning brush will come in handy when cleaning hard-to-reach areas or removing stubborn build-up. Make sure the bristles are soft to avoid scratching any surfaces.

Step-by-Step Cleaning Process

Step 1: Unplug and Disassemble

The first step in cleaning the Keurig water reservoir is to unplug the coffee maker from the power source. This is essential for safety reasons. Once unplugged, carefully detach the water reservoir from the Keurig machine. You may need to consult the user manual for specific instructions on how to remove the reservoir.

Step 2: Empty and Rinse

Next, empty the water reservoir completely. Dispose of any remaining water and rinse the reservoir with clean water. This will help remove any loose debris or particles.

Step 3: Prepare the Cleaning Solution

If you opt for vinegar as your cleaning solution, mix equal parts vinegar and water in a separate container. For example, if you have a cup of vinegar, mix it with a cup of water. If you choose a commercial descaling solution, follow the instructions provided on the package to prepare the solution.

Step 4: Clean the Water Reservoir

Now it’s time to clean the water reservoir. Using a cleaning cloth or sponge, dampen it with the vinegar or descaling solution. Wipe down the interior of the reservoir, paying particular attention to any areas with visible build-up or residue.

Step 5: Scrub with a Toothbrush

For stubborn residue or hard-to-reach areas, use a toothbrush or cleaning brush. Gently scrub the affected areas to loosen any trapped debris. Be careful not to apply too much pressure to avoid damaging any surfaces.

Step 6: Rinse and Dry

After cleaning the water reservoir with the vinegar or descaling solution, thoroughly rinse it with clean water. Ensure all traces of the cleaning solution are removed. Once rinsed, use a clean cloth to dry the reservoir completely before reassembling it with the coffee maker.

Additional Tips and Recommendations

Cleaning the Keurig water reservoir is essential for maintaining the quality of your coffee and prolonging the lifespan of your coffee maker. Here are a few additional tips and recommendations to keep in mind:
