How to Clean a Coffee Maker: 7 Brands (Ninja, Bunn, Bella, Keurig…)

How to Clean 7 Brand Name Coffee Makers

Let’s look at how to clean some of the popular brand name coffee makers.

There should be care and cleaning instructions that came with your machine so make sure to check just in case we’ve missed something.

Tip: Always make sure the empty carafe is in your machine to catch the dirty water while cleaning your machine.

1. How to clean Cuisinart coffee maker

Cleaning a Cuisinart coffee maker is a simple process. Make sure you follow the cleaning process at least once a month if not more so that you don’t get bacteria growth or mold.


  • water
  • vinegar
  • nonabrasive scrubby pad/brush
  • mild dish soap

Steps to clean a Cuisinart coffee maker:

  1. Rinse: Run a complete cycle without coffee grounds using a paper filter to help remove scale and gently lift grime. Discard the water.
  2. Sanitize: Use a mix of 1/3 white vinegar and 2/3 water and run a cycle to sanitize the unit and kill any lingering bacteria or mold. If your machine has a “clean” button you can press it (while the machine is plugged in but turned off) and then when it glows turn the machine on and it will be in clean mode. When you hear five beeps the cleaning mode will be finished. Otherwise, proceed with the next steps
  3. Rinse again: Run another cycle or two of plain water to remove any vinegar and finalize the cleaning process.
  4. Scrub the carafe to remove grime and allow everything to dry completely before your next use.
  5. Soak as required: If you have trouble removing the coffee film from the carafe try letting it soak in hot soapy water for a few hours (or overnight) and then gently scrub with warm soapy water and a little vinegar.

2. How to clean Ninja coffee maker/bar

The Ninja coffee bar is easy to clean, but make sure you do it regularly so build up doesn’t interfere with your system. Follow these few steps to get it just right.


Steps to clean Ninja coffee maker:

  1. Descale: Fill the water reservoir with a mixture of water and a descaling solution. Select “full: on the portion size indicator and press “clean”.
  2. Rinse: When the clean cycle is finished discard the solution and run another two cycles using just plain hot water to remove any lingering grime or solution.
  3. Scrub as required: Clean the carafe and any removable machine parts with hot soapy water to remove film and build-up.
  4. Allow the machine to dry completely to avoid mold growth

3. How to clean a Bunn coffee maker

The Bunn needs to be cleaned about every two weeks to make sure that all the components are in working order. Make sure you keep the brush head that comes with the machine so you can easily clean the spray head.


  • cleaning tool
  • soapy water
  • vinegar

Steps to clean a Bunn coffee maker:

  1. Clean spray head: Detach the spray head carefully and clean it with the brush component to remove any scale.
  2. Brew some water: Clean the machine by running a cycle through with just plain water to make sure that any grime is loosened.
  3. Brew some vinegar: Use a mix of 1/3 white vinegar and 2/3 water and run a cycle to sanitize the unit and kill any lingering bacteria or mold.
  4. Final scrub: Clean the carafe with a mixture of water and vinegar to make sure that the film lifts completely. Thermal carafes can be more difficult because you can’t see all the build-up, but the addition of the vinegar should help remove the stains.
  5. Brew some more water: Run one or two more clean cycles of plain water to remove all vinegar.

Here's how we make our coffee:

Here is the gear we use everyday as we make strong, rich coffee at home.

Depending on the day, we make our coffee in one of three methods.

  • Espresso Maker: Breville Cafe Roma. This is a (relatively) inexpensive espresso maker that makes a quality shot. It has a small footprint, taking up little space on our counter. This was a gift from Bryan's parents.
  • Drip Coffee Maker: Ninja Coffee Bar with Stainless Steel Carafe. This unit makes good drip coffee. It also has an insulated carafe, keeping coffee hot without making it gross - like those little burner plates on most coffee makers. Dena's go-to every morning.
  • Stovepot Moka Pot: Bialetti Stovetop Moka (Espresso) Pot. This is Bryan's favorite for first coffee of the day.
  • Coffee Grinder: Cuisinart Coffee Burr Grinder. We've been using this grinder for many years and it still grinds consistently. This was a gift from our daughter.
