How Often Should I Clean My Bunn Coffee Maker?

Every time that you use your coffee maker you should be cleaning it out. That means wiping down everything you can and rinsing out the machine with soapy water. That doesn’t mean you need to go through the full cleaning process though.

Each month you should be going through a full cleaning process and descaling to make sure that you get rid of any of the buildup that can occur during normal use.
