Hey guys. I seem to be getting excessive dark mold on my Romano and have to keep scrubbing it clean every few days. It is very difficult to get off with a paper towel dipped in white vinegar. I end up having to scrape it off. My Humidity level is pretty consistent at 82-85%. I tried lowering it a bit for a few days but it was too dry and I got a crack in the rind. Is there any way I can slow the mold from not forming as much?
