Unless you use other people's razors.Unless you are running a barbers, or sharing your shaving equipment, I remain cynical on this obsession with Barbicid. If you cut yourself, it's your blood, and your germs, your body is clever enough to know how to deal with it. A run under a hot tap, with some soap if you'r fussy, is more than enough. In 40 years, the only time I have ever disinfected razor equipment is when I sell it on...
Then it's their blood and their germs.
If you don't buy vintage or second hand and don't participate in pass arounds - no need for Barbicide.
