Perfume is not a cleaner. Bleach is an effective cleaner for hep c.
However, I’m not sure how hep c infected blood if such existed on the handle could then be transferred to a fresh razor. This just doesn’t sound like a likely scenario of an effective means of transmission.
Hep c infected blood must enter the blood stream of an uninfected person.
If a new razor was used there is no way it could have another persons blood on it
Perfume is not hep c infected blood so not sure how you think perfume could be a risk
To become infected with hep c requires hep c infected blood to enter the blood stream of an infected person. The most common avenues for infection is the sharing of IV drug needles or having a transfusion prior to 1990 when testing was developed for hep c antibodies.
Also unlicensed medical facilities reusing needles would be a risk. Tattoo shops that don’t properly clean their equipment between customers. The sharing of personal hygiene items like razors, fingernail clippers, and toothbrushes which could be contaminated with blood is also a potential risk.
