Tom W in San Antonio
New member
I have had a 18.5" WSM for a little over two years and love it. I store my charcoal chimney starter inside when not in use. I keep the WSM cover on the unit when not in use and leave all vents open to circulate air. Today, I uncovered the smoker to get the chimney out to use with my Weber kettle and found significant mold build up. We have had the wettest September in San Antonio since records have been kept. I have not had a mold problem in the previous two years of use. Once I get it cleaned up, should I keep all of the vents closed or not? Thanks for any advice. Tom
