I would use Isopropyl Rubbing Alcohol or, even better, bleach to sanitize your blades. I know this may sound kind of crazy but the CDC (Center for Disease Control) here in the states advises intravenous drug users who share needles to disinfect them with bleach to sanitize them of any viruses/bacteria. However, I'm not an expert on this topic, so, I'm only saying what I've heard. I don't know what effect the bleach will have on a carbo-steel blade. I'm not too sure about Barbacide. I know what it is but I don't know what it has in it to sanitize.
