Howdy. For the last bit of Lent, I didn’t use warm water in the sink for my shaves. What I noticed is that when I drained the sink, a LOT less soap scum was left behind. I switched back to warm water after Easter, and the heavy ring of soap scum has returned. Hmm. Has anyone else made this observation? (Probably. There’s nothing new under the sun, and there are many lifetimes’ worth of shaving experience on B&B.)
