How to Clean a Coffee Maker Water Reservoir

Cleaning the water reservoir of your coffee maker is an essential task to ensure the quality and taste of your coffee, as well as to maintain the longevity of the machine. Over time, mineral deposits, oils, and bacteria can build up inside the reservoir, potentially affecting performance and hygiene. With a few simple steps, you can keep your coffee maker in excellent condition and enjoy fresh, great-tasting coffee every day.

This guide on how to clean a coffee maker water reservoir will walk you through the process of properly cleaning the water reservoir.

Why is It Important to Clean Your Coffee Maker Water Reservoir?

Your coffee maker’s water reservoir is where you add the water that will be used to brew your coffee. If the reservoir is not cleaned regularly, it can become a breeding ground for bacteria and mold. This can lead to a funky taste in your coffee and, even worse, potential health hazards.

Moreover, mineral deposits from hard water can accumulate inside the reservoir and clog the machine’s inner workings. This can affect the flow of water and result in weaker or slower brewing.

Cleaning your coffee maker’s water reservoir should be done every few weeks, depending on how frequently you use it. If you notice any strange odors coming from your coffee maker or your coffee tastes off, it’s a sign that the reservoir needs a thorough cleaning.

Needed Materials

Before diving into the cleaning process, make sure you have the following materials on hand:

Distilled White Vinegar:

This is a natural cleaning agent that can effectively remove mineral deposits and kill bacteria.

Water:

You will need water to rinse out the vinegar after cleaning.

Clean Cloth or Sponge:

This is to wipe down the exterior of the coffee maker and remove any residue inside the reservoir.

Dish Soap:

Optional, but it can be used for an extra thorough clean. Make sure to rinse thoroughly afterward.

8 Step-by-step Guides on How to Clean a Coffee Maker Water Reservoir

Step 1: Prepare 

Start by unplugging your coffee maker to ensure safety during the cleaning process. Then, remove the water reservoir if it is detachable. Empty any remaining water from the reservoir and set the coffee maker on a stable, flat surface.

Gather all the needed materials, such as distilled white vinegar, water, a clean cloth or sponge, and dish soap if desired. Having everything ready will make the cleaning process smooth and efficient.

Step 2: Vinegar Solution 

Mix a solution of equal parts distilled white vinegar and water. This mixture is highly effective at breaking down mineral deposits and eliminating bacteria or mold inside the reservoir.

If your coffee maker’s water reservoir is particularly dirty or has a strong odor, you can use a slightly higher ratio of vinegar to water for a stronger cleaning solution. Gently pour the vinegar solution into the water reservoir, filling it to its maximum capacity.

Step 3: Soak 

Allow the vinegar solution to sit in the reservoir for about 15 to 30 minutes. This soaking time will give the solution an opportunity to break down stubborn mineral deposits, eliminate bacteria, and loosen any buildup inside the reservoir. Avoid turning on the coffee maker during this step, as the goal is to focus on thoroughly cleaning the reservoir before running the machine.

If the buildup is particularly tough, you can gently swish the solution around inside the reservoir to help dislodge any debris.

Step 4: Scrub 

After the vinegar solution has soaked, use a clean cloth, sponge, or soft-bristled brush to scrub the inside of the water reservoir. Pay extra attention to corners, edges, and any areas where mineral buildup or residue is visible. Be gentle while scrubbing to avoid scratching the surface of the reservoir. 

For stubborn spots, dip your scrubbing tool into the vinegar solution and apply a bit of extra pressure to remove the residue. If your reservoir has a narrow opening, consider using a bottle brush to ensure you can thoroughly clean all areas. Once the scrubbing is complete, pour out the vinegar solution and inspect the reservoir to ensure all buildup has been removed.

Step 5: Rinse 

Once the scrubbing is complete, thoroughly rinse the water reservoir with clean, warm water. Make sure to rinse multiple times to remove all traces of the vinegar solution. Any leftover vinegar could impact the flavor of your coffee, so take care to ensure the reservoir is completely clean. If your reservoir is detachable, you can hold it under running water, tipping and rotating it to rinse every corner.

For non-detachable reservoirs, use a clean sponge or cloth soaked in warm water to wipe away any remaining solution. After rinsing, inspect the reservoir to confirm it is free of vinegar or debris before proceeding to the next step.

Step 6: Optional Dish Soap Clean 

If you prefer an extra thorough clean, you can use a small amount of dish soap to wash the reservoir after the vinegar rinse. Add a drop or two of mild dish soap to a clean sponge or cloth, then gently scrub the inside of the reservoir. Be sure to reach all corners and edges to remove any lingering residue or buildup. 

Once you’ve finished cleaning with dish soap, rinse the reservoir thoroughly with warm water. It’s crucial to remove all soap residue, as even a small amount can affect the taste of your coffee. To ensure the reservoir is completely clean, rinse multiple times and check for any remaining soapy bubbles before moving to the next step.

Step 7: Exterior Wipe-Down 

While the inside of the reservoir is drying, take a moment to clean the exterior of your coffee maker and the water reservoir. Use a clean, damp cloth or sponge to wipe down the outer surfaces, removing any stains, dust, or coffee splashes. For any tough spots or sticky residue, you can dampen the cloth slightly with a mild dish soap solution. 

Be sure to clean around the edges and seams where dirt might accumulate. Avoid using abrasive scrubbers or harsh cleaning agents to prevent scratching or damaging the finish. Once the exterior is clean, use a dry cloth to gently wipe it down, leaving the surfaces spotless and ready for use. This step helps maintain the overall appearance and hygiene of your coffee maker.  

Step 8: Final Rinse 

Once the reservoir is fully dry and the exterior is wiped down, you’re ready for a final rinse. Fill the water reservoir with clean, fresh water and run your coffee maker without any coffee grounds or filter. This final rinse will ensure all remaining residue or soap is removed, leaving your coffee maker clean and ready to brew delicious cups of coffee again!

Following these simple steps on how to clean a coffee maker water reservoir will help keep your coffee maker’s water reservoir clean and free of any buildup, ensuring you can continue to enjoy great-tasting coffee every day. Regularly cleaning the water reservoir is an essential part of maintaining your coffee maker and prolonging its lifespan. Make it a weekly or monthly habit, and you’ll not only have a clean reservoir but also a well-functioning and long-lasting coffee maker.

Additional Tips and Maintenance

• As mentioned, it is important to regularly clean your coffee maker’s water reservoir every one to two months, depending on how often you use it. This will help prevent any buildup or bacteria growth and ensure your coffee always tastes fresh.
