It's the highlight of your morning to sit down with a steaming mug of coffee. You were the one who looked up BUNN coffee maker reviews online and convinced your family that you absolutely required one. However, your coffee maker, like all other kitchen appliances, will eventually become grimy, so you shouldn't skip cleaning it along with the rest of the kitchen.  

Your Bunn coffee maker might not be as simple as it seems. Mineral deposits can build up on the inside of your coffee maker even if the outside looks spotless, making it easy to overlook the fact that it needs cleaning. If not cleaned regularly, a coffee maker's soiled interior can quickly become a bacterial hotbed.  

You need to know how to clean a Bunn coffee maker if you are in charge of the morning coffee at the office or if you are a serious caffeine addict at home. Read on for a comprehensive guide to the ins and outs of keeping your Bunn coffee maker clean and sanitary. We'll cover everything from why it's important to clean your brew machine to how to tell when it's time to clean.  

The Importance of Keeping Your Coffee Machine Clean

There are many benefits to keeping your coffee machine clean. A purified machine has many advantages, including a shorter brew time and less bacteria. Some examples:

Coffee makers can back up the water supply if mineral deposits and scaling build up inside. As a result, your coffee will take longer to prepare because of the slower drip. On the other hand, if you keep your machine tidy, water will flow smoothly and your coffee will be ready in no time.

As was previously mentioned, scaling deposits can restrict water flow, rendering your coffee brewing efforts futile. When water flow is restricted, equipment malfunctions. It's important to clean your coffee maker regularly to ensure it works well.  

Everyone dislikes it when their coffee tastes bitter, and dirty coffee makers are usually to blame. Damage to an instrument's internal temperature gauge can be caused by grime and dust. A lack of heat can diminish the flavor.  

Protecting your Bunn coffee maker with regular cleaning will ensure that it lasts for as long as possible, giving you more time to enjoy its many benefits.  

Brewing coffee requires the use of both heat and water in your coffee maker. Because of this, germs, yeast, bacteria, and occasionally mold can flourish in your device. If you suffer from allergies or get an infection, you may experience negative side effects from this.  

Locations most prone to harboring bacteria in coffee makers

Are you aware that the reservoir of your coffee maker is one of the dirtiest places in your home or workplace? There is the potential for coffee makers to harbor more bacteria than some bathroom fixtures. Incredible, right? Not with the factors of humidity, heat, and constant use.  

It may come as a shock to learn that the disposable coffee cups you (and everyone else in the office) use every day are teeming with germs if you work in an office setting. It makes sense, when you think about all the dirty hands that have handled the cups: eventually, everyone who drinks coffee will touch them.  

One of the grimiest components of a coffee maker is the handle. If you share a coffee maker with anyone, whether at work or at home, you should avoid touching the handle.  

The Best Ways to Keep Your Coffee Maker Germ-Free

  • Empty the coffee grounds, discard the used filter, and wipe dry with a paper towel or clean cloth after each use.
  • If you want to start the day with a fresh pot of coffee, soak the carafe in warm, soapy water.
  • To prevent mold growth, remove the top of your coffee maker and let it air out.  
  • To ensure the best possible hygiene, run the dishwasher after each use to clean the carafe and basket.  
  • Use a disinfectant or wash the handle in warm, soapy water after every use.  

Learn the Signs That It's Time to Clean Your Coffee Machine.

There are a number of telltale signs that your coffee machine is overdue for a thorough cleaning. However, it is recommended that you make cleaning your coffee maker part of your pre-brew ritual. Don't risk a broken machine and bad cup of coffee by ignoring these warning signs.  

Some of the more frequent pitfalls are as follows.

  • The coffee you just made smells and tastes awful.  
  • Inside the coffee pot, there are stains.  
  • Coffee brewing takes an inordinate amount of time.  
  • You find chalky residue inside your machine in various places.  
  • The water is sputtering into the carafe rather than flowing smoothly, as can be heard and seen.  
  • The coffee output from your machine has decreased.  

Tips for Maintaining Your Bunn Coffee Maker

cleaning coffee grounds out of filter

Each time you use the coffee maker, you should clean it and remove the used grounds from the basket. Every three months, you should give your coffee maker a thorough cleaning by descaling it. However, this is conditional on the mineral content of the water being used and the frequency of its application.

Common Practice for Cleaning

Follow these steps to clean your Bunn coffee maker the conventional way: Do this regularly, preferably every time you use the machine.  

First, Power Down the Equipment

Make sure the appliance is unplugged before beginning cleaning. You must take this precaution in order to avoid being electrocuted. You will need water for the cleaning process, and there may be some left in the carafe or machine.  

Remove the coffee filter and discard the grounds.

Rinse the coffee basket to get rid of any leftover grounds, then discard the grounds and filter (if using one).

Three, Clean the Outside

Use a gentle cloth dipped in warm water laced with a drop or two of unscented or mildly scented dish detergent to wipe down the surfaces. It's a good idea to clean the outside of your device. Then, wipe your device down with a clean, damp cloth that hasn't been touched by soap.

Carafe sanitization and soaking is the fourth step.

Rings of a brownish color can be seen inside the carafe on occasion. This is perfectly normal and can be washed away with some soap and water. Clean the inside of the carafe with a washcloth and some warm soapy water. Wait a few hours, then rinse and dry it.  

Carafes can also be cleaned with a vinegar and water solution, baking soda, or the dishwasher.  

Clean the Spray Nozzle (Step 5)

The water in most coffee machines is dispersed through a spray nozzle. Take apart the spray head and check it for clogs. Remove the mineral deposit or coffee grounds using a small object, like a toothpick. After that, wash the nozzle with some gentle dish soap and warm water using a clean cloth.  

Prepare the Spray Tube for Use Step 6

A metal or plastic tool for cleaning the spray tube is included with some Bunn models. First, take out the spray nozzle and the brew funnel. After that, place the cleaning tool inside the tube and rotate it slowly while pushing it up and down. Reconnect the spray nozzle to the brew funnel after deposits have been removed.

Method for Thorough Cleaning

When was the last time you took the time to descale your coffee maker? Perhaps you're not even familiar with that term. Here, there will be no judgment of any kind, so relax.

Calcium and magnesium deposits can form on the inside of your machine if you use filtered, mineral, bottled, or tap water. Limescale is a chalky buildup that can be removed through a process called descaling. ” 

Heat causes minerals in water to form oxide layers, which can clog pipes, dull coffee flavor, and eventually cause equipment failure. After waiting patiently for it to brew, the last thing you want is a cup of coffee that tastes burnt, clogged, or otherwise unpleasant because of these problems.  

Although deep cleaning isn't something you should do every day, coffee makers that see regular use should be given the treatment at least once every three months. If you want to know how to thoroughly clean your Bunn coffee maker, here are a few simple steps you can follow:

The First Step: Creating a Solution

Blend together a bowl's worth of vinegar (about half a cup) and distilled water (about two thirds of a cup), depending on the model of Bunn you own.  

Second, begin brewing.

To fill the water tank, combine the vinegar and distilled water. And then you start the brewing process. Allow the carafe to fill with water, discard the solution, and power down the coffee machine. Limescale can be effectively removed from the reservoir's interior by allowing the solution to soak there for about two hours.  

Third, clean the nozzle and tube of the spray gun.

You can clean the spray nozzle by unscrewing it, wiping it down with a soapy cloth, and then using a toothpick or other small utensil to scrape away any deposits. After that, wash with warm water. Use your metal or plastic deliming tool, as described above, to clean the spray tube.  

Second Brew #4: Get Going!

Put everything back together again (the spray head and the spray tube). Start the machine and fill the water tank with distilled water. Let the brewing process continue. By doing so, you can ensure that the solution no longer smells like vinegar. Keep doing this until the smell disappears completely.  

The Top Products for Cleaning

It's safe and effective to clean your machine with lemon juice, baking soda, and vinegar. Cleaning the exterior of the machine or the carafe with mild or unscented dish soap is another great option.  

Learn why these all-natural cleaners are the best option for your coffee machine.  


One of the most powerful natural disinfectants is the acid in lemons. Due to its antibacterial properties, it is able to remove hard water stains and eliminate sediments from your coffee machine. Additionally, a refreshing citrus aroma will be left behind, which is a nice bonus.  


Vinegar is a common household cleaner, and it works especially well on coffee makers that get a lot of use. It can decalcify your machine, clean out the residue, and disinfect it all at once.  

Sodium Bicarbonate, or Baking Soda

Baking soda, which is inexpensive and has many other useful applications, is another common choice for cleaning a coffee machine. In addition to removing stains and odors, this coffee pot cleaner also eliminates bacteria.  

You can clean your coffee maker in a number of ways, and you can even combine different cleaning agents to make a more powerful solution. Optionally, you can combine equal parts of lemon juice and baking soda. Use this paste to clean your coffee maker and have fresh coffee and no worries in no time at all.  

Another option is to combine about half a cup of vinegar with one eighth of a cup of baking soda (exact amounts will vary with different models). These two effective cleaners work best when given more time to work their magic. Once you see the fizzing, you'll know it's doing its job.  

Precautions to Take When Cleaning Your Coffee Machine

  • Avoid using chemical-based cleaning supplies. This could cause damage to both you and the machine.  
  • Don't start cleaning your Bunn coffee maker until you read the manual, as there may be important details there that you'd otherwise overlook.  
  • Don't try to disassemble anything that isn't specifically addressed here; you'll probably end up with more questions (and more mess) than you started with.  
  • Soaps with strong fragrances should be avoided because they can alter the flavor of the coffee.  
  • Machines can be dangerous to clean if done so while plugged in or while still hot.
