Best soap with hard water?
So I'm new to this site, but have been shaving with a straight razor for a while now. I've always preferred using puck style soap; I guess I'm old fashioned like that. The issue I'm now facing, though, is extremely hard water. We moved into a new apartment a little while back. It's nice but for the fact that the building has no water softener and the town sits on limestone. It's hard to make any sort of lather here. Our dishes don't get clean, my wife can't take her bubble bath, and I can only whip up the thinnest of lathers in my shaving mug. I need to shave immediately after my shower and be extremely careful with the razor. Those are good habits, to be sure, but does anyone know of a soap which works well with hard water? I can't bring myself to buy bottled water just to shave with it.
