“For my fermentation equipment, I like to use Iodine instead of Chlorine Bleach. You can use standard Povidone Iodine - 5mL to 2000mL. Rinse really well afterwards. I make my own Iodine Concentrate using Lugol's Iodine. A soak in either Povidone Iodine diluted in water or a custom Iodine Solution using Lugol's create's the same environment - a 2 min soak creates an environment suitable for brewing whereas a 5 minute soak meets medical sanitation standards. For our Stainless Steel bottling and blending and herbal prep surfaces, we use a 70/30 blend of Ethanol to Distilled Water. I purchase 100% pure Ethanol and dilute with 30% by volume of Distilled Water and we keep spray bottles filled with those all the time. For air, we use a Blue Air Filter and also occasionally run an ozone machine, too, depending on the operation at hand. And unless I'm working with really volatile solvents, we also burn various incenses that are known to purify the air and neutralize various airborne bacteria and fungi, such as Frankincense and Myrrh Resin."
