Thanks for the info, Bruno!
I was wondering what I could do to disinfect a razor prior to use on somebody else... I mean... imagine a friend who asks you to try out a straight razor, or even a friend who wants to try one "barber-shop-style" (you being the barber...). If you plan on giving the Sweeney Todd treatment I guess the cleaning of the razor wouldn't be much trouble... Hepatitis is nothing compared to a slit throat!
I wonder what barbers used back then... anybody care to share some intel on that?
Thanks!
