What You’ll Need:

Before you start cleaning your Bun coffee maker, you’ll need a few items. These include:

White vinegar


Dish soap

Soft cloth

Paper filter

Step 1: Unplug the Coffee Maker

The first step in cleaning your Bun coffee maker is to unplug it from the power source. This is essential to avoid electrocution or any other potential accidents.

Step 2: Remove the Filter Basket

Next, remove the filter basket from the coffee maker. Depending on the model of your Bun coffee maker, you may need to twist it or lift it out. Once removed, discard any used coffee grounds and rinse the basket under running water.

Step 3: Prepare the Cleaning Solution

To prepare the cleaning solution, mix equal parts of white vinegar and water. For instance, if you’re using one cup of water, mix it with one cup of white vinegar. You can use a measuring cup to ensure you get the right ratios. If you don’t have white vinegar, you can use a descaling solution specifically designed for coffee makers.

Step 4: Fill the Water Tank

Fill the water tank of your Bun coffee maker with the cleaning solution. If you’re unsure of the amount to use, check the manual that came with your coffee maker. Once you’ve filled the water tank, return it to the coffee maker.

Step 5: Start the Cleaning Cycle

Turn on your Bun coffee maker and allow it to run through the cleaning cycle. This will typically take 15 to 30 minutes, depending on the model of your coffee maker. During this time, the cleaning solution will circulate through the machine, removing any buildup or debris.

Step 6: Rinse the Coffee Maker

After the cleaning cycle is complete, empty the water tank and rinse it thoroughly under running water. Refill the water tank with clean water and run the coffee maker through a brewing cycle without any coffee grounds. This will help to flush out any remaining cleaning solution from the machine.

Step 7: Clean the Exterior

While the coffee maker is still unplugged, use a soft cloth to clean the exterior of the machine. You can use mild dish soap and warm water to remove any dirt or stains. Avoid using abrasive cleaners or scrubbers that could damage the finish.

Step 8: Clean the Filter Basket

To clean the filter basket, use a soft brush or sponge to scrub away any remaining coffee oils or stains. If the filter basket is particularly dirty, you can soak it in a solution of warm water and dish soap for a few minutes before scrubbing it.

Step 9: Clean the Carafe

To clean the carafe, fill it with warm, soapy water and let it soak for a few minutes. Then, use a soft sponge or cloth to scrub away any stains or debris. Rinse the carafe thoroughly under running water and dry it with a clean towel.

Step 10: Reassemble and Enjoy

Once you’ve completed all the cleaning steps, it’s time to reassemble your Bun coffee maker. Replace the filter basket and carafe, and you’re ready to start brewing fresh, delicious coffee once again!

Tips for Maintaining Your Bun Coffee Maker

Cleaning your Bun coffee maker regularly is essential for keeping it in top condition. However, there are a few other tips you can follow to ensure your coffee maker lasts for years to come.

  1. Use high-quality coffee beans: Using high-quality coffee beans will not only improve the taste of your coffee but also reduce the buildup of oils and debris in your coffee maker.
  2. Use filtered water: Using filtered water instead of tap water will help prevent the buildup of minerals in your coffee maker and improve the taste of your coffee.
  3. Empty the carafe after each use: It’s important to empty the carafe after each use to prevent any leftover coffee from turning rancid and leaving behind unpleasant odors and flavors.
  4. Clean the coffee maker monthly: In addition to regular cleaning after each use, it’s recommended to deep clean your Bun coffee maker at least once a month to remove any stubborn buildup.
  5. Replace parts as needed: Over time, the filter basket, carafe, and other parts of your coffee maker may wear out and need to be replaced. Be sure to check the manual for your coffee maker to see when parts should be replaced.


How often should I clean my Bun coffee maker?

It's recommended to clean your Bun coffee maker after each use and to deep clean it at least once a month.

Can I use other cleaning solutions instead of white vinegar?

Yes, you can use a descaling solution specifically designed for coffee makers. However, avoid using bleach or other abrasive cleaners that could damage your coffee maker.

How do I know when it's time to replace parts of my Bun coffee maker?

Check the manual for your coffee maker to see when parts should be replaced. Generally, the filter basket, carafe, and other parts may need to be replaced after several years of use.


Cleaning your Bun coffee maker is a simple process that can help improve the taste of your coffee and extend the lifespan of your machine.

By following the steps outlined in this guide and maintaining your coffee maker regularly. You can ensure that you’re enjoying a fresh, delicious cup of coffee every day.
