@rbl just posed a really good question regarding whether distilled water is adequate to use for microwave steaming our equipment. We've been told that distilled water potentially carries NTM. If we only microwave the equipment for 3 minutes (per instructions) with 4 oz of distilled water in the bag, how can NTM be destroyed in that short of time, assuming that the front part of the 3 minutes is at lower than boiling temps? The equipment may be undergoing only a couple of minutes of optimal steam time.
