If you’re reading this, there’s a good chance you own a Ninja Coffee Bar. Let’s take some time to appreciate this beautiful machine that makes our favorite coffee drinks. It’s one of the most diverse drip coffee makers on the market. It has such a wide range of settings that we can drink almost anything we can expect a drip coffee maker to make. It even has a milk frother! This amazing coffee maker is very simple and also very easy to clean.

Cleaning is a very important part of any coffee brewing maintenance. It helps your machine keep working properly and producing quality results longer. Not to mention that all the filth that builds up inside the machine will grow bacteria, and no one wants that. Today we will learn how to clean a Ninja Coffee Bar to keep it running at its best.

How Do You Know When to Clean?

The Ninja Coffee Bar system has a light at the bottom left that says “Clean.” This illuminates when the system senses it needs to be cleaned. This is a good indicator, but you can always opt to clean your machine once every two months. If you use it every day, once a month is a good interval.

The Cleaning Process

There are actually two processes to clean your Ninja Coffee Bar. Clean the outside components with soap and water. Then, clean the inside using white vinegar. We will explain both processes.

The Outside: Soap and Water

  1. Start by cleaning the parts that are easily removable, such as the brew basket and coffee measuring spoon. These can be wiped down with a wet rag or rinsed with hot water.
  2. A cloth that is moist and has some soap should be used to wipe down the outside. This removes milk or coffee stains to make the outside sparkle. Some soap residue might remain, so wiping down with just water after the soap doesn’t hurt.
  3. When cleaning the temp warming plate, use caution. It is a fragile piece. Cleaning it with soap and a sponge is the easiest and does a great job getting it clean (shown in photo).

The Inside: White Vinegar

The Instruction Manual states that white vinegar or the Ninja descaling solution can be used. For this guide, we are showing you how to use white vinegar to clean your Ninja Coffee Bar.

1. Rinse Cycle: The best way to start is to run the brewer with water. This gets rid of any leftover grounds or any other yucky things stuck in there before vinegar does the rest of the work. To do this, place your carafe under the pour spout. Make sure the water reservoir is full, then press the “Full Carafe” button to run the water through.

  • Put in 16 ounces of white vinegar, which goes to the “Travel Mug” line
  • Then add water to the “Max Fill” line.

3. Cleaning Cycle: (shown in photo below)

  • Place the carafe underneath the pour spout.
  • Select the “Full Carafe” setting.
  • Press the “Clean” button to run the machine and let the magic happen.

A countdown will begin on the screen. This process can take up to 60 minutes, but it’s worth it once you see what it cleans out!

4. Flush Cycle: After the vinegar is done going through the machine, always run water through it again. The screen display on your machine will say “Flush.”

  • First, rinse your carafe out and then place it back under the pour spout.
  • Fill your water reservoir back to the “Max Fill” line.
  • Select the “Clean” button, and the machine will go through an eight-minute flush cycle.
  • The “Clean” light will turn off when the cycle is complete.

The flush cycle is important because it will help with the strong odor vinegar can leave behind and get rid of any residue left in the machine that can affect the flavor of your coffee. The vinegar water can be disposed of down the drain.

5. Clean your glass carafe: You used it to catch all the nastiness coming out of the coffee system, so it deserves a good washing. It is dishwasher safe, but if you do use the dishwasher, be sure to use the top rack. Otherwise, you can hand-wash it like you would anything else.

How to Clean the Milk Frother

Cleaning the milk frother is only necessary after you use it, but make sure to clean it after EVERY use. This is easier than you think, but here’s a photo and steps to guide you.

  1. Grab a glass and fill it halfway with hot water.
  2. Stick the milk frother at least halfway or more into the glass and hold it straight up and down (as shown in photo).
  3. Turn on the frother by pressing the button on top. Hold it for about 20-30 seconds to get all milk residue off the frother.

General Tips

We added some more tips to make cleaning easier for you! Check them out:

  • Only use white vinegar. Using other kinds of vinegar or cleaners can damage the machine, and then you won’t be able to have coffee at all.
  • Your machine will dim during the cleaning cycle. Don’t press any other buttons during the cleaning cycle or flush cycle.
  • If you really hate the odor of vinegar, try putting lemon into the water you use for the flush cycle at the end. It gives a more refreshing scent for those with sensitive noses.
  • Use the Instruction Manual to take extra safety precautions. The experts know what they’re talking about.


With these steps, you should have a clear insight into how to clean all parts of your Ninja Coffee Bar machine. Hopefully, knowing the number of bacteria that can grow inside a coffee machine is motivation enough for you to try this yourself. It’s easy yet can still be time-consuming, but it is one of the best things you can do for your coffee habit. Happy cleaning!
