If you regularly use a home coffee maker, chances are you don’t think about what’s lurking inside it. the National Sanitation Foundation says bacteria, mold, and even yeast love to grow in your machine and that’s why you have to clean it.
Senior Product Manager for NSFLisa Yakassays coffee makers are relatively safe…. IF you clean them according to manufacturer guidelines. Surprisingly, she says the water reservoir is the grimiest part of the whole machine… and your kitchen!
Yakas has a big tip for you, besides cleaning the machine. Always empty the reservoir and leave the lid off to keep it dry. Most gross organisms live dark and damp areas to grow.
