We'll teach you how to clean a Bunn coffee maker to extend its lifespan and keep your coffee tasting great. It's not too tricky, but there are a few handy tips and tricks you should know that will make cleaning your machine much easier.
Make sure the machine is off before you start cleaning it. Unplug the machine from the outlet to eliminate the possibility of accidentally turning it on mid-clean.
Prepare a mixture of mild detergent or soap and warm water. You will use this solution for cleaning the outside of the machine.
Soak a cloth in the detergent solution and thoroughly wipe down the outside of the machine. Make sure you don't miss any spots, paying careful attention to the area around the spray head.
Rinse the cloth and wipe down the machine again to remove the detergent. It is important not to let the detergent linger on the surface for too long. Even mild detergents can cause damage if they are left in contact with susceptible surfaces for too long.
Remove the spray head from the machine. Using the spray head cleaning tool or another pointed object, remove any built-up coffee residue from the spray head openings. This step can be time-consuming depending on how long it has been since you last cleaned the spray head. Take your time and make sure the spray head isn't clogged before moving on to the next step.
While the spray head is still detached, use the long end of the spray head cleaning tool—or another similar tool—to clean inside the spray head housing. This is a common trouble area prone to mineral deposits and residue, so don't be surprised if there is a lot of buildup to remove.
Reattach the spray head to the machine and enjoy your newly cleaned Bunn coffee maker.
Descale Your Bunn Coffee Maker
Make a solution of one part vinegar to two parts distilled water. Vinegar is acidic and can easily break down calcium deposits. Make enough solution to fill your Bunn's coffee pot.
Pour the descaling solution into your coffee maker and initiate a brewing cycle.
Perform at least three to five rinses by running a brewing cycle with only water. If you don't rinse the machine enough after descaling, your coffee will have an unpleasant vinegar taste.
Notes
It will be helpful to have some supplies on hand before you get started. Most of the equipment needed are household items, except for a spray head cleaner. Bunn makes a specialized tool designed for cleaning the spray head on their machines. It isn't strictly necessary to use a spray head cleaner, but having one makes the process much easier. They aren't too expensive, so you should consider picking one up.
