Just loosen the head and rinse it under the tap. Blow it out & Pat it dry.
If you really think you need to, take it apart & Pat it dry after each use.
Vigourouly rubbing it will do more harm that good.
When you change a blade, strip it down using a soft childs toothbrush GENTLY clean each part with hand soap/brush and set aside.
Rinse off then pat dry & wait a bit (rest until dry your next shave would be good).
Fit new blade then your ready to go.
If you do what you are thinking of doing you will be buying a new razor every couple of months.
If its bacteria you are worried about, get a couple more razors, rotate them do a basic clean when changing a blade, hand soap soft brush regime. Leave a razor standing in a drawer or cupboard any thing on it is dead in 72hrs.
This is shaving. Its happened for centuries without men dropping dead from the dreaded dirty razor plague.
Just my thoughts on the matter, by the way tomorrow I will be using a razor that's over 100years old, I dont think it killed any of its previous owners.
