Someone was telling me that in the good old days shaving soap was kept in the bottom of a mug (Scuttles were for people with money) and water was added to the mug and the soap and the brush soaked together for a few minutes before emptying the water from the mug. The brush would be lightly shaken to remove the excess water and then you would load the brush on the wet soap before face lathering. At the end of the shave the soap was squeezed out back into the mug (never throw away good soap was the comment) and then the brush was rinsed out before being sat on its end to dry.

Anybody seen or tried this method. Would it work with modern soaps or would they disintegrate in the soaking water?
