I understand the idea of caution--but I have to question your pattern.
1 hour of treatment with a wide spectrum anti-bacterial anti-viral seems reasonable. Adding 2 weeks in a (presumably sterile? presumably single use?) sealed container to ensure things are dead...okay. But then ANOTHER 1 hour treatment of the same disinfectant means, to me, that you aren't actually being rational. You're being paranoid. Why are you assuming that anything that survived the previous treatment would *not* survive the second?
As for the risks involved in razors...everything has risks. Some risks are more immediate than others, some risks are more avoidable than others, but every human behavior has some element of risk. So the question is, how much time and effort is acceptable in the reduction of risk? The only real answer is the amount of peace of mind the action gives you...because peace of mind is the only measurable result of your actions.
So I think your actions are extreme and difficult to justify, but if they make it easier for your to deal with the facts of human mortality, then more power to you.
Me, I think a short alcohol soak and a wash with triclosan gives enough peace of mind to go on with my shaving.
