Not true, heat kills mold, bleach kills mold, amonia kills mold, vinegar kills mold and yes ozone kills mold (but is not the only thing)
Google it
I would advise heat
I apologize, I thought we were looking for practical solutions relative to processing the hash. You are correct, heat does kill mold spores, but only at a particular temperature and pressure that an autoclave (laboratory sterilizing appliance) can provide.
I think maybe our misunderstanding here is based on a technicality. Once spores have germinated and their physical structure is that of a hyphae (or fuzzy appearing structure that you are familiar), mold is susceptible to various cleaning agents. However, mold SPORES are very difficult to kill: ozone, UV light, autoclave (doesn't kill all spores), and biocides (which are chemical solutions engineered to lyse the spore membrane) are the only ways to kill mold spores. I didn't think that any of these would be useful, w/ the exception of ozone. I attached a couple of links that I could find, but didn't have enough time to find everything. Riddle, if you have some literature that I need to read up on, please forward it to me as I am always wanting to educate myself, but vinegar (acetic acid) is pH = 2.4. If I remember correctly, many spores can w/stand this is pH, but I could NOT find specific documentation.

Hope all is well. Cheers, dak
