Most of these "Sterilize vintage razor" threads talk about heat or chemical disinfecting, but what about mechanical sterilization? I'd think hitting a blade with a dremel using the steel brush wheel, then nylon brush with polishing compound, then buffing wheel with polishing compound, then again the nylon brush with Maas(which has a lot of ammonia in it) , then buffing wheel polishing compound.
I don't think any microbes could survive that kind of attack.
