I’ve had a recent problem with mold in my keezer. I live in the Sacrameno area – dry in summer, cool – sometimes moist in winter (rainy season). I setup my keezer last summer – no issues. However, over the winter I developed a mold problem. I’ve added a tub of damp rid (http://www.damprid.com/) to the keezer. After just 1 day – the smell of mold is gone – let’s see how this works.
