I've been soaking my tube of creme in my sink of hot water while I shower with my brush. I found this create a wonderfully warm lather that just a warm bowl and brush cant touch. Can anyone see a reason that I shouldn't do this.
As much as practical, I prewarm my soap pucks too. My Mama Bear soap containers I float around in the hot sink and my other soaps are in mugs that I immerse in the same.
A vegetable based cream such as Tom's of Maine (no longer made) can benefit from a warm soak in that it will mix faster and more completely. I can't see any drawback to warming up a tube of cream because the product is supposed to be used with hot water when it's lathered.
