Well, I started inspecting... they were in a tray on the shelf above the first drawer









The back left of the tray had the water marks (back center of wineador)









I took everything out (spilled one container of KL in the process...









Here's what my KL setups look like. Cookie tray in bottom with ballet tight wrapped around it to prevent spillage and MOW Puro Authentico boxes for other levels.









Everything out and now I'm scared... I've found two more. WTH happened???









I think I spotted the reason: water marks coming from the fan...









Wife found a 32oz water cup with cut lemon and lime spilled on the back of it all dried up that one of the kids must have spilled. It appears the old fruit water went in and dripped through the fan into the trays up against the back of the humi. It was sometime within the last month but that's as close as I can be certain of.









I'm scouring all of these now... would freezing kill of any mold spores I couldn't see yet? What do I do to treat the sticks? Should I bake the cedar at low temps to dry/kill mold? Trying really hard not to be irrationally mad at the family right now - stuff happens, but this is a real kick in the nuts!
