I hestitate to revive an old thread, but yesterday was hot here, and I couldn't stand the thought of hot towels, etc for my shave. So I use cold tap water, used a Cella soap and Semogue boar brush and went at it cold, after washing my face first with warm water. I got a DFS with no drag or pull, and some of my usual "problem areas" like my chin and neck went much better. All in all a good shave. I'm going to try it again.
