I think Barbercide is a fool proof disinfectant for razors, if you follow the directions. There are several warnings here on the forum about the scales and the possibility of color/shape/texture distortion.

At Sally's Beauty Supply, and likely other cosmetology supply stores, you get a 16oz bottle of Barbercide for free when you buy the Barbercide jar. Probably cheaper to rig up your own container & buy the concentrate outright. But that jar sure is snazzy in the shave den!
Gonna actually use mine once my project razors are restored enough to shave with, or if I loan one out. Like others said: not all that necessary, unless it is a "new to you" razor, or it will change hands (loaned/sold).

I do like the "antirust formula". Thats just good SR shaving peace of mind. In one thread here, a member said they give their blade a quick dip (literally, not soaked in it) as the last step before air drying after every shave. I might adopt that once I mix up a jar :).
