How Dirty Is Your Coffee Maker? (2:45)

When was the last time you cleaned your coffee pot? Findings from a small 2011 National Sanitation Foundation (NSF) study found the most bacteria in home kitchens and appliances like coffee makers and reservoirs. Along with bacteria and microorganisms, mold and yeast were also present in significant concentrations. Don't rely on the hot water in your coffee maker to kill off all the germs. In fact, the moist environment inside the appliance can increase bacterial and fungal growth. If you use your coffee maker daily, make sure to wash the carafe, lid, and filter basket after every use. Every month, brew a vinegar and water solution to decalcify the machine from the inside out. Print this simple one-sheet as a reminder to regularly clean your coffee maker.
