Well, we tossed the manchego today. Even after cutting off the rind, the musky smell had made its way into the cheese, so into the compost pile it went
I looked in the cheese cave and found a little drain/drip pan/drawer under the small freezer that had MOLD on it :'(. OK, that's it, the pan is now no longer in the cheese cave-- also took the door of the small inside freezer off so it is more open to air. Washed everything down with hot soapy water. Next is a treatment with StarSan. I'm going to get that cheese cave clean.
Also we are changing our cheese mats from the bamboo sushi rolling mats to plastic mats that can be sanitized in the dish washer, bought a sink mat for $5 that I can cut to fit in the tupperware containers. I can't seem to get the bamboo mats clean even after boiling them for 20 minutes.
