I could not understand why so many people hated Williams Mug Shaving Soap. I know now, I headed out on a week business trip with my trusty williams converted to a shave stick. Some of the hardest water I have shaved with. The lather disapeared in seconds. I just used more and shaved with the slime for 3 days till I got close to a bath and body works to grab a tube of C. O. Bigelow. It was ok, not wonderful, with the hard water. I want to keep a stick of shaving soap when I travel. What soaps work well with hard water for you guys?
