(Thanks to an expert here on AB for putting me on track).
Mold infections develop from two sources, airborne spores and their fungal organisms that need to have some material to grown on. Airborne spores are best controlled by a well ventilated room. Most of the mold growth in terrariums comes from spores and their 'plants' in the materials you put in. Dirt, woody material and occasionally plants. The problem in eradication of the molds is their spores are present, some of which are wearing armor. More than just armor but full isolation PPEs.
Four common methods.
1. Bake the materials in an oven. Problem: some spores will survive until you bake that log or branch to ashes.
2. Non latent biocide. You are pretty much limited to chlorine bleach. However, bleach has a problem. It's molecules are like guns, each with one bullet. Once fired, it's useless. And, there is a good chance you have a lot more spores than chlorine molecules since those molecules are also chewing on everything else..
3. Nearly all common molds need moisture. Remove all moisture, now and forever, and never allow it into the containment again. Along the lines of teaching poodles to fly.
4. Acetic acid. Aka vinegar.
It's the gift that keeps on giving. Given enough time it will chew into spores, viruses, bacteria, and just about all other micro-organisms. However, it can take some time. In my tests with the bad news bear, Stachybotrus Chartarum, black mold, weak acetic acid solutions, vinegar, takes 24 to 72 hours to play havoc with those spores.
Recommended procedure: Immerse the materials in straight vinegar. Come back in a week and rinse thoroughly. If you happen to be a little mental, like me, immerse in hot 80% acetic acid and wait a half hour. This method is not recommended as it will not only dissolve the spores but also your favorite decorative woods, slaughter your plants, and eat your lungs and sinuses. The only part of living organisms acetic acid finds indigestible is the chitin and some components in bone.
