It seems like we can read piles of posts about every other bit of shaving minutia on this forum, but for all I've heard about using a "hot towel" as part of prep, I don't think I've ever read how you make a towel hot! So my questions are: 1. Is this just a towel/rag soaked in hot water and wrung out? Or is it dry? Is it microwaved? Roasted on an open fire? What??? 2. How do you incorporate a "hot towel" into your shave? 3. Does anyone actually do this as part of their daily shave? Just seems like extra laundry (and time) to me! 4. What's the purpose? Does it really do anything that washing with hot water and lathering with hot lather doesn't do? Thanks!
