I am still a relative noob when it comes to wet shaving. Came back after 30+ yrs of electric. I have watched nearly every video on Youtube about shaving and devoured the threads on B&B. (I travel so I have lots time to kill in the hotel). Great stuff. Anyway, I don't recall ever seeing anything about warming pre-shave oils. This morning I tried it. I put my brush and my bottle of American Crew oil in the sink with hot water while I took a shower. when I put the oil on it applied beautifully and felt terrific. Used mrko stick and a Derby Extra blade. The blade was a few days old because I left my other blades at home (Doh!). Still got a great shave, no nicks and very little sting from my Alum bar. Does anyone else heat their oil? I certainly will be from now on.
