  1. Ensure that the Keurig Duo is unplugged from the power source.

  2. Remove the water reservoir from the machine by lifting it straight up. Be cautious as it may contain hot water if it was recently used.

Carefully remove the K-Cup holder from the brewer and empty any loose grounds from the holder.

Step 2: Disassemble The Holder

Step 3: Clean The K-Cup Holder And Its Parts

Soak the K-Cup holder in a mixture of warm water and white vinegar (equal parts) for 15 minutes to dissolve the oils in the holder. Use a soft-bristle brush to clean the K-Cup holder and its parts, then rinse thoroughly under running water.

Step 4: Clean The Funnel And Drip Tray With Mild Soap

Using a mixture of mild soap and warm water, clean the funnel and drip tray. Rinse thoroughly under running water and dry the components with a clean cloth.

  • Fresh water
  • Mug or container
  • Lint-free cloth

Step 1: Prepare The Descaling Solution

If you’re using a descaling solution specifically designed for coffee machines, follow the manufacturer’s instructions for dilution. If you prefer using a natural alternative, white vinegar can be an effective descaling agent. Mix equal parts of white vinegar and water to create a descaling solution.

Step 2: Empty The Water Reservoir And Remove Any K-Cups

Ensure that the water reservoir is empty and remove any K-Cups or carafe from the machine before proceeding with the descaling process.

Step 3: Fill The Reservoir

Pour the prepared descaling solution or white vinegar mixture into the water reservoir of your Keurig Duo. If using white vinegar, it’s recommended to fill the reservoir halfway to avoid overfilling with the strong-smelling liquid.

Step 4: Start The Brewing Cycle

Place a mug or a container on the drip tray to collect the descaling solution as it brews. If your Keurig Duo has a carafe, make sure it’s placed securely on the drip tray. Begin a brew cycle using the largest cup size setting, allowing the descaling solution to flow through the machine.

Step 5: Discard The Solution

Once the brew cycle is complete, discard the contents in the mug or container. If using a descaling solution, ensure to follow the manufacturer’s instructions for proper disposal. If using white vinegar, you can simply discard the liquid down the sink.

Step 6: Rinse The Reservoir

Thoroughly rinse the water reservoir with fresh water to remove any remaining descaling solution or vinegar.

Step 7: Perform Multiple Brewing Cycles

Fill the water reservoir with fresh water and brew multiple cycles without a K-Cup or carafe to flush out any residual descaling solution or vinegar from the system.

Step 8: Clean The Drip Tray And Exterior

Use a lint-free cloth dampened with water to wipe down the exterior of the Keurig Duo and clean the drip tray. This will remove any traces of the descaling solution or vinegar, ensuring that your machine is clean inside and out.

Descaling your Keurig Duo at regular intervals, as recommended by the manufacturer, will help prevent mineral buildup and ensure that your machine continues to produce delicious, unadulterated coffee with each brew.

Frequency of Descaling For Keurig Duo

Over time, mineral deposits from the water you use can accumulate in the internal components of your Keurig Duo.
