Well, with my small germ compulsion, even though I don't have to do the following, it takes care of my paranoia.

I have two jars from olives. One had Barbicide solution in it. After quick hot water rinse and soap wash a short soak (blade only) while I rinse brush, face and apply balm. The other has a mixture of 91% alcohol/mineral oil. A dip in and out, fingertip smoothing of mixture up to the tang/pivot area, light wipe down if needed and store.

I have a low humidity bathroom because of a half Siamese cat that objects to closed doors (she likes my company) and living alone with her makes it possible to have all but touch up stuff in there where I can admire my over spending at any time.
