What you might try is use a second mug for hot water only. Soak the brush while showering, then drain the brush and whip up later. I believe, although I have not confirmed, you should get better life out of your soap. I haven't tried this, as I bought some Vulfix cream at the same time, and it makes nice lather, smells good, and lasts forever.
I see, that helps a lot. A further question for you, then: when you buy a tub of shave cream, in your view, is it cost effective compared to soap cakes (I have in mind those which cost 4-5 dollars/ cake, e.g. classicshaving, or col. conk). And I guess, another question (if you don't mind): what are the directions for using shave cream from a tub?
Thanks,
