Descaling Your Ninja DualBrew Hot & Iced Coffee Maker


Welcome to our comprehensive guide on descaling your Ninja DualBrew Hot & Iced Coffee Maker! I understand the importance of water quality in the home, especially when it comes to brewing a perfect cup of coffee. Descaling is a critical maintenance task that ensures your coffee maker functions optimally, preserves the flavor of your coffee, and prolongs the appliance’s lifespan. In this article, we will walk you through the process of descaling and its impact on your coffee brewing experience. Let’s dive in!

Features and Benefits of Ninja DualBrew Hot & Iced Coffee Maker

The Ninja DualBrew Hot & Iced Coffee Maker comes with several features designed to enhance your coffee brewing experience. Let’s take a closer look at each one:

  • Multiple Brew Sizes: The coffee maker offers various brew sizes, catering to both individual servings and carafes. Choose from a small cup up to a full carafe.
  • Grounds and Pods: Included adapters allow you to brew grounds or pods.
  • Advanced Thermal Flavor Extraction Technology (TFE): This technology optimizes the extraction process, unlocking the full flavor potential of your coffee grounds, resulting in rich and robust coffee.
  • Over Ice Brew: Enjoy smooth and refreshing iced coffee with the Over Ice Brew feature, specifically designed to brew coffee at a lower concentration, compensating for ice dilution.
  • Intelligent Clean Cycle: The coffee maker alerts you when it requires cleaning, ensuring consistent performance and eliminating any lingering flavors from previous brews.

Why Descaling Matters for Your Coffee Maker

Descaling is the process of removing mineral deposits, primarily calcium and magnesium, which accumulate over time due to hard water usage. These deposits form a chalky, white residue that affects the efficiency of your coffee maker, alters the taste of your coffee, and diminishes the overall brewing experience. Here’s why descaling is crucial:

  • Superior Coffee Flavor: By removing mineral deposits, descaling allows the natural flavors of your coffee beans to shine through, delivering a richer and more satisfying taste in every cup.
  • Efficient Brewing: A clean coffee maker ensures optimal water flow and brewing temperatures, leading to consistent results and a hassle-free brewing process.
  • Prolonged Coffee Maker Life: Regular descaling reduces the risk of damage caused by scale buildup, extending the lifespan of your coffee maker and saving you money on repairs or replacements.
  • Enhanced Water Softener Performance: If you’re using a water softener, descaling your coffee maker complements the softener’s efforts by preventing scale formation, leading to even better water quality for your coffee.

Descaling Your Ninja DualBrew Hot & Iced Coffee Maker

Descale your Ninja DualBrew Hot & Iced coffee maker any time the orange CLEAN light turns on, when the display says CLN, or when the brewing cycle starts taking longer than usual. These are all indicators that there is mineral build-up in the coffee maker.

Follow these steps to descale your coffee maker effectively and ensure the best water quality for your coffee:

Step 1: Gather the Materials

Step 2: Prepare Your Coffee Maker

  • Remove any remaining coffee grounds from the filter and discard them.
  • Empty the carafe

Step 3: Create the Descaling Solution 

  • Option 1: White Vinegar Solution
    • Add 16 ounces of white vinegar to the water tank then add clean water until the solution reaches the Max Fill line. 
  • Option 2: Commercial Descaling Solution
  • Follow the instructions on the descaling product’s packaging to create the solution.

Step 4: Run the Descaling Cycle

  • Pour the descaling solution into the water reservoir of your coffee maker.
  • Place the empty carafe beneath the brew basket.
  • Start the descaling cycle by pressing the CLEAN button and select FULL CARAFE.
  • The clock will display the countdown time.
  • Allow the solution to run through the coffee maker completely.
  • NOTE: the cycle takes about 75 minutes.
  • When the cycle is complete, the machine will beep and the display will show END.

Step 5: Rinse Thoroughly

  • Once the descaling cycle is complete, empty the carafe and the water reservoir and rinse them thoroughly with clean water.
  • Fill the reservoir with clean water and run a brewing cycle without any coffee grounds to flush out any remaining descaling solution.

Step 6: Clean External Parts

  • While the internal descaling cycle is essential, don’t forget to wipe the external parts of your coffee maker with a soft cloth to keep it looking pristine.


Descaling your Ninja DualBrew Hot & Iced Coffee Maker is a vital maintenance task that significantly impacts your coffee brewing experience. By removing mineral deposits and preserving the quality of your water, descaling ensures a flavorful and consistent cup of coffee every time. For an even better coffee experience, consider using filtered and softened water in your coffee maker. Filtered water removes impurities, while softened water prevents scale buildup, both contributing to a delightful coffee experience. Embrace the art of descaling, and elevate your coffee brewing to new heights!


How often should I descale my Ninja DualBrew Hot & Iced Coffee Maker? 

Descaling frequency depends on the hardness of your water and how often you use the coffee maker. The display will show CLN or the clean light will come on when it is time to clean your Ninja DualBrew coffee maker.

Can I use vinegar for descaling? 

Yes, per the owner’s manual, you may use white vinegar for descaling your coffee maker instead of a coffee maker descaler. Add 16 ounces of white vinegar to the water tank, then add clean water until the solution reaches the Max Fill line. Be sure to rinse the coffee maker thoroughly with clean water after descaling.

Are there any descaling products specifically designed for Ninja coffee makers? 

Yes, some descaling products are designed for use with Ninja coffee makers. Ensure that the product is compatible with your model, and follow the instructions provided by the manufacturer.
