Why Does My Coffee Maker Smell Like Mildew?

Why does your coffee maker smell like mildew? This unpleasant odor often arises from moisture accumulation, which fosters mold and bacteria growth in the reservoir and tubing.
Using unfiltered tap water can lead to mineral buildup and stagnant water, both detrimental to coffee quality. Additionally, if you leave coffee grounds or residual coffee in the machine, they can become moldy, further contributing to the mildew smell.
Neglecting regular cleaning allows mold spores to thrive in hard-to-reach areas like the water reservoir and filter basket. The water temperature you use can also affect mold growth; higher temperatures may accelerate it.
To combat these issues, incorporate a vinegar solution into your cleaning routine to effectively eliminate mildew odors and maintain your coffee maker’s performance.
